ensures output with a professional and crisp look.
Rugged Construction for Long Life
The HP 5000 D640 is ruggedly constructed for years of printing at the rated monthly duty
cycle and for continuous operation without danger of damage to the print engine, a capability
especially important for peak printing periods such as month-end processing.

Accessories For the D640 Printer
About Your Printer 1-3
About Your
Printer
Toner Recycling and Economy Mode Printing
The D640 supports both toner recycling and economy printing mode for greater toner yields.
Toner recycling can increase toner yield by up to 20%. In economy mode, toner usage is
reduced by up to 30% with minimal impact on text print quality.
High Capacity Paper Handling
The D640 features a maximum standard input capacity of 1500 sheets in three 500-sheet paper
trays. Maximum standard output capacity is 400 sheets. Addition of the High Capacity Input
(HCI) accessory increases the total input capacity to 4500 sheets. The High Capacity Output
(HCO) accessory handles up to 2000 sheets and supports output jogging for job separation.
Custom Paper Size Support
The D640 supports non-standard paper sizes with a custom paper tray. Paper sizes as small as
4.75 inches by 7.2 inches (120 mm x 182 mm) or as large as 11.7 inches by 17 inches (297 mm
x 431.8 mm) can be accommodated. The custom paper tray can be used as tray1, tray2, or
tray3. When using more than one custom paper tray, each tray must contain the same size of
paper.
Backlit LCD Display
The D640 features a backlit, menu-oriented, Liquid Crystal Display for ease of configuration
and printer management. Five different languages are supported (English, German, French,
Spanish, and Italian).
Multiple Interfaces
The D640 features integrated Bitronics (parallel) and serial interfaces and supports automatic
switching between these two interfaces. HP JetDirect EX external network interfaces
(purchased separately) provide Ethernet/IEEE 802.3 or Token Ring IEEE 802.5 LAN
interfaces. The same network management software used with HP LaserJet printers and HP
JetDirect cards can be used with the D640 and HP JetDirect EX products, allowing networked
HP printers to be administered and managed with a common set of software tools.
PostScript Level 2
PostScript is available for the D640 as an add-on product and includes an additional 16
megabytes of memory. The printer can be configured to automatically switch between
PostScript and PCL print jobs.
Accessories For the D640 Printer
1-4 About Your Printer
Compatibility with LaserJet 4Si/5Si Printer
The HP 5000 D640 is compatible with the HP LaserJet 4Si printer driver. However, because
the D640 provides more functionality than the HP LaserJet 4Si, not all D640 features can be
accessed with the 4Si printer driver. You can use third party products or additional
programming to access additional D640 features.
The HP 5000 D640 is also compatible with the HP LaserJet 5Si printer driver. However, there
are a few limitations when using the LaserJet 5Si printer driver. Please refer to Chapter 6,
"Advanced Topics", for a discussion of LaserJet compatibility.
PCL Level 5e
The D640 printer supports PCL, the print language of HP LaserJet printers and the most
widely installed print language in the world. Support for PCL Level 5e provides powerful
formatting capabilities and compatibility with a wide range of software solutions.
Integral Hard Disk
The D640 features an internal hard disk drive(850 MB or more) factory preloaded with
thousands of fonts and symbol sets. The hard disk can also be used for storing additional fonts,
electronic forms as PCL macros, and company logos.
Energy Star Compliance
To help minimize power consumption, the D640 complies with the Energy Star Program of the
U.S. Environmental Protection Agency.
Note If you have not done so, please refer to the Installation Manual and complete the
installation procedures. These procedures ensure the safe operation of the printer and the best
print quality.
The printer requires regular maintenance, as described later in this manual. Although
maintenance takes only a few minutes weekly, it is very important to the quality of the
printouts and the life of the printer.
Caution Hewlett-Packard recommends the use of Hewlett-Packard labelled consumable
supplies. Hewlett-Packard is not responsible for any failures or print quality issues arising
from the use of other than Hewlett-Packard supplies. Such failures are not covered under
warranty or by any Hewlett-Packard service agreement.

Introduction
The D640 printer performs many kinds of printing tasks. Through the Control Panel menus,
you can select options and features.
If your print job contains commands that change the Control Panel settings, the print job
commands will be effective for that job only.
This chapter is a detailed reference for all of the D640’s menu settings:

Control Panel Features and Functions
The Control Panel is one of the means to control and configure the printer. Through the
Control Panel, the printer displays information about aspects of normal operation, paper jams,
consumable status, and error conditions. Use the function buttons on the Control Panel to
change printer settings.
Control Panel features include:
• The Standby switch turns the printer on and off:
- When you move the Standby switch momentarily to the ON (or up) position, the printer
powers on. There will be up to a 2 minute delay before you can print while the printer
performs an initialization sequence and warms the fuser to operating temperature.
- When you move the Standby switch momentarily to the OFF (or down) position, the
printer is powered off and placed in Standby mode. There may be a delay in the printer
powering off; any pages currently moving through the paper path are printed before the
printer powers off.
• The Screen contrast control adjusts the contrast of the LCD panel.
• The Function buttons are located below the LCD panel. These five buttons perform
different functions during printer operations, such as when the printer is printing, or when
you are changing settings. Figure 2-6 shows these function buttons.

• The Speaker is not currently activated.
• The Liquid crystal display (LCD) panel displays printer status and operating information.
Figure 2-6 shows the basic menu screen, called the Main Screen. Messages on the Main
Screen:
- Show information about printer status, progress of the print job, and the current paper
path.
- Display the paper size configured for each input source.
- Show any paper jams in the paper path line.
•The PowerSave indicator, when on, indicates that the printer is in PowerSave mode. The
backlight of the LCD panel also turns off in PowerSave mode.
Checking Printer Status
You may want to check the D640’s status for many reasons:
• To verify that it is ready for printing.
• To verify that it is either Online or Offline.
• To check that the correct date, time, and printing protocol are set.
Normal Printer Status (No Error Condition Displayed)
The message field of the display shown in Figure 2-2 reports the D640’s status.
Figure 2-2 Printer status
The message field information indicates:
• Ready -- free
The printer is ready to print.

Abnormal Printer Status
The message field (the first and second line) of the Control Panel reports the printer’s
conditions, such as low toner, paper jam, or door open. In these cases, the Control Panel also
describes what action is needed to remedy the situation. Serious conditions may require a
service call. Error messages are listed in Appendix A.
The printer constantly monitors the state of consumables such as developer and toner. When a
consumable runs low, or has reached its end-of-life, a message notifying you to replace the
consumable appears on the Control Panel. An example of such a report is shown in Figure 2-3.
Figure 2-3 Toner empty indication
The printer detects when a cover is open and stops printing to protect you from electrical and
mechanical hazards. If a cover is open, the printer reports the condition, like the screen shown
in Figure 2-4.
Note Do not open a cover while the printer is printing; this will cause a paper jam.

configured for a LaserJet print correctly on the D640 without
modification.
To match a IIIsi or a 4si, change HCI-Alias to tray2. This will
cause all print job commands for tray2 (or lower tray) to pick
paper from the D640 HCI.
For more information, see “Configuring for LaserJet IIIsi and
4si Compatibility” on page 6-24.

Font Sets the default character font.
Symbolset Sets the default symbol set (character set) of the font specified in the font setting. A
symbol set is a collection of letters, numbers, and symbols designed for specific
applications such as scientific equations and international language.
Pitch
Sets the default pitch size for the fixed-pitched font. Pitch is the number of characters that
can be printed in one horizontal inch. For example, a font with a pitch of 10 will print 10
characters for every horizontal inch of text. If a proportionally-spaced font is selected in
the font menu, pitch will not appear on the PCL menu.
Pointsize This setting specifies the point size for the scalable font. Pointsize is the height of the font
measured in point (1/72 of an inch).
Virtual
Font
Cartridges
The D640 printer is designed to be compatible with the HP LaserJet 4si. The 4si has two
slots available for font cartridges. HP sells over 50 different font cartridges for 4si and
compatible printers.
The D640 has no slots to hold these cartridges. Instead, we provide the same
functionality with virtual font cartridges. All of the font sets from all of the LaserJet 4si font
cartridges sold by Hewlett-Packard are stored on the D640’s internal hard disk drive. You
select the virtual font cartridge by vcartridge1 and vcartridge2. The font names are
comparable to the actual physical cartridge. For a complete list of the fonts available,
refer to “Using Virtual Font Cartridges” on page 6-26.
Note: Fonts located inside a font cartridge cannot be the printer default font.

Setting Custom Paper Sizes
The custom paper tray can accommodate a wide range of paper sizes, using continuously
adjustable paper guides.
The custom paper tray can accommodate paper stock as small as 4.75 x 7.2 inches (120 x 182
mm) or as large as 11.7 x 17 inches (297 x 431.8 mm). You can install one or more custom
trays in the printer, but they must all be set to the same size.
There are two tasks in setting up custom paper sizes in the custom tray:
• Define the custom tray.
• Set the paper size in the printer menu settings. (Save the dimensions and menu numbers in
case you must refill the tray at some other time.)
1. To specify a tray as the custom tray, press PapSize on the Main Screen (Figure 3-13) to
display the screen shown in Figure 3-14. This display identifies the paper size in each
tray.

Configuring Custom Tray Menu Settings
You must first interpret your paper dimensions into settings the printer can understand.
Basically, you must accurately measure your paper’s width and height (also called length)
using standard inches (inches) or millimeters (mm), and converting the numbers into printer
units.
For example, using a 5 x 8 inch card:
1. The card is printed with the short side (5 in) as the leading edge. The menu setting for
the leading edge is width.You could also select the long side as the width.
2. The 8 inch side is height. You could also select the short side as the height.

3. The printer has many printer unit options. (A unit is simply a measure of size used to
give you fine control over image placement on the page.)
For most jobs sized in inches, use 1/100" as the unit size.
4. Multiply your paper height (length) by the number of units per inch (in our example, 100
x 8 = 800).
If you use a unit size of 1/200", the number would be 1600; if the unit size was 1/720",
the number would be 5760, and so on. If you are using the mm unit setting, no multipli-
cation is necessary.

Loading Paper Into Trays and HCI
This section explains the proper paper loading process, which depends on the type of paper
used and the print job requirements.
Follow these basic guidelines to select and use paper and other media (transparencies, labels,
etc.) for the D640:
• Use only paper labeled specifically for non-impact or laser printing, xerographic copying,
or duplicating. Refer to “Media Selection Specifications and Guidelines” on page D-3 for
complete media specifications.
• Use only one kind of paper in a tray at a time; mixing types of paper can cause jams.
• Do not overfill the paper trays or HCI (note the maximum fill line).
• The HCI is supported for use with paper media only.
Opening Paper
1. Remove the paper from the package, with the package seam side up, as shown in
Figure 3-25. Read the manufacturer’s packaging end-label and note the direction of the
arrow. The arrow points to the side that should be printed first, also referred to as the
face side.
Figure 3-25 Removing paper from the package
2. Inspect the paper for indented or interlocked edges, bent corners, wrinkled sheets, and
excess glue from the wrapper. Discard any damaged sheets.
3. Load the paper into the printer tray or HCI as recommended in the paper loading
illustrations provided in Table 3-2.

Locking Paper Trays
All paper sources with the same size of media are automatically linked together. This means
that the printer will automatically switch to the next tray when the current tray runs out of
paper. This could cause problems when all of the paper trays are set to the same size of paper,
but contain different types of paper, such as plain paper and letterhead.
In order to eliminate the linking of trays, you must "lock" the trays you don’t want selected
unless the job gives a direct command to use paper from that source.
For example, if you have a tray with letterhead paper in it, you may want to lock out this tray
so that if the other trays run out of paper, the letterhead paper tray would not be used.
The printer does not detect the paper size loaded in a particular tray.
Follow this procedure to lock a paper tray:
1. On the Main Screen, press Menu.
2. Press N to move to Configuration (Figure 3-26).

The choices available are:
Clearing a Paper Jam
When you start a print job, the printer selects paper, a page at a time, from one of the internal
trays or from the external HCI. Paper jams may occur if the paper is wrinkled, folded, skewed,
or out of specification. The printer goes Offline until the paper jam is cleared.
When a jam occurs, refer to the Control Panel for a visual and written description of the jam
location. For a visual indication refer to the picture on the right side of the Control Panel. The
area in the paper path where the jam occurred will be blinking.
More than one sheet of paper may be located in the paper path; all sheets must be removed
before the printer will resume printing.
In this case, the paper path diagram may continue blinking in the same or another location, and
the printer displays messages about the location of remaining sheets until all jams are cleared.
Note The printer is forced Offline until the problem is fixed.
Table 3-3 lists each paper jam that displays on the Control Panel and how to clear the jam.
More detailed information on clearing paper jams appears on the pages listed. You can also
refer to the illustrated jam clearing pictures located on the inside of the printer’s front door.
PAUSE Temporarily stops the job. Use this to pause the printer, such as when adding or
removing paper or adding toner.
ENDDOC
Any incomplete or partial pages are printed (like a form feed or page eject). The job
ends normally and the printer is ready for another job. This is typically used when the
print job has no end-of-job command, and the Control Panel displays Ready -- wait
for a long time.
SUPPRESS
Continues to process the current job, but the resulting pages are not printed. Printing
resumes with the next job. Select SUPPRESS when you no longer want to print the
current job, but you want to retain data, such as downloaded fonts and macros,
needed for future jobs. SUPPRESS is the recommended way to end routine print
jobs.
ABANDON
Ends processing of the current job and clears all data in the input buffer. This is the
most direct, quickest, and potentially risky way of stopping a current job. Use
ABANDON only when you are certain that the data in the print job is not required by
future print jobs.

Handling Error Messages and Troubleshooting
An error message can be caused by mechanical problems, such as jams, or by incorrect
settings, such as specifying the wrong paper size from the wrong paper tray. These are typical
printer problems than can be easily cleared by the user.
Printer errors that are caused by mechanical or electrical problems are also reported by specific
error codes. These problems require a service call to your service representative.
An error message is always accompanied by an action message, as shown in Figure 3-70.

Refer to “Error Messages” on page A-7, for how to interpret error messages.
In the unlikely event that the printer has a major error, follow these steps:
1. The printer may self-diagnose the problem and possibly display the message as shown in
Figure 3-71.
2. Write down the error code and message that appears on the Control Panel.
3. Refer to “Call Engineer Error Messages and Codes” on page A-8 to determine the
meaning of the error code.
4. If the error code calls attention to a specific physical component or location on the
printer, check the area specified and correct the problem.
5. If you cannot resolve the problem, call your service representative. Be prepared to give
the service representative the error code and any messages that appear on the Control

Introduction
This chapter provides user maintenance procedures to maintain the printer’s consumables.
If you want: Go to:
• An overview of the D640 printer supplies page 4-1
• To order additional consumables page 4-2
• To replace toner or recycle toner after replacement page 4-4
• To replace developer and ozone filter page 4-9
• To replace the drum and transfer assembly page 4-18
• To replace the fuser page 4-29
• To replace the printer pick rollers page 4-33
• To replace the HCI pick rollers page 4-42
Overview of Consumable Supplies
You can replace all of the consumable supplies. This chapter presents step-by-step instructions
for removal and replacement of these supplies and explains how to set the printer to produce
lighter or darker prints.
• Each time you replace a consumable, the action is automatically recorded in the printer’s
online maintenance log.
Caution Damage to the photoconductor can cause excessively light or dark printing or
missing text.
Caution Hewlett-Packard recommends the use of Hewlett-Packard labelled consumable
supplies. Hewlett-Packard is not responsible for any failures or print quality issues arising
from the use of other than Hewlett-Packard supplies in the cut sheet printer. Such failures are
not covered under warranty or under the Hewlett-Packard service agreement.
Ordering D640 Printer Consumables
4-2 Ordering and Replacing Consumables
Ordering D640 Printer Consumables
You can order consumables directly from Hewlett-Packard by calling 1-800-538-8787 in the
United States and Canada. Customers outside the United States and Canada should contact
their local Hewlett-Packard sales office.
Please plan for a two to five day delivery in the United States, possibly longer outside the
United States. If your printer was purchased from a Hewlett-Packard reseller, you may be able
to purchase consumables directly from them.
Table 4-1 lists the D640 printer consumables, ordering numbers, kit content descriptions and
quantities, along with the length of time you can expect them to last under optimum operating
conditions.
Use the replacement cycle estimates in Table 4-1 to plan your initial consumable purchases.
Because yields may vary widely from the estimates, you should track your actual usage to
establish proper replacement schedules for each printer installation.
Actual yields depend upon:
• Media (paper type, weight, chemical composition, perforations, paper dust, and quality).
• Media storage factors such as care and handling, room temperature, and humidity.
• Exposure to light (photoconductor drum).
• Frequency of cleaning the printer.
• Average print job size, daily print volume, and patterns of printing.
• Ambient environmental conditions, such as temperature, humidity, and static electricity.
• Power-on hours.
“Managing Consumables” on page 6-6 describes some of the considerations in using and
replacing consumables.

Consumables
Table 4-1 Consumables, product part numbers, and replacement cycles
Note A new printer will report toner low and need to be refilled the first time after printing
about 6,000 images. This is normal and is due to the toner hopper being completely empty in a
new printer.
The estimated yields listed are not a warranty or guarantee of minimum life and are provided to
assist in initial supplies planning. Yields may vary widely based on applications and operating
conditions.
Yield estimate are based on, but not limited to, ideal environmental and operating conditions,
print jobs averaging 4% toner coverage per page, and an average job of 25 pages.

Replacing Toner
4-4 Ordering and Replacing Consumables
Replacing Toner
The toner comes in a kit that contains bottles of toner, empty toner collector bottles, and fuser
cleaning rollers. The toner collector bottle is replaced with every bottle of toner. The fuser
cleaning roller is replaced after every two bottles of toner.

cleaning routines to follow:
• a short weekly cleaning routine that removes paper dust and stray toner particles from the
exterior of the printer.
• a more thorough internal cleaning procedure that should be performed when you replace
the drum.
Weekly Cleaning
Investing just a few minutes on your D640’s maintenance each week ensures minimum
downtime and maintains high print quality. Make sure someone is responsible for printer
maintenance. Perform the maintenance tasks at the recommended intervals.
Use these tools for cleaning:
• Cleaning cloths (supplied with the D640 printer)
•Rags
• Vacuum cleaner specially designed for picking up toner
• Blower brush (supplied with the D640 printer)
Note Turn the main power switch OFF before performing the weekly cleaning.
Caution Make sure that the toner vacuum is properly grounded before using it in the printer,
or the printer may sustain electrical damage. Refer to the vacuum’s operating manual.

Removing Stray Toner
During removal or replacement of various consumable parts, toner occasionally spills onto the
printer interior or exterior.
• Do not attempt to clean up spilled toner with water or any other fluid, as this can harm the
developer, toner, and printer mechanism.
• Use a vacuum cleaner especially designed for trapping toner particles. Regular vacuum
cleaners cannot trap the fine toner particles and will exhaust them back into the air. If you
are unsure which vacuum cleaner to use, consult your service representative.

This chapter presents information about:
• Maintaining print quality
• Managing consumables
• Adjusting paper path alignment
• Setting up edge-to-edge printing
• Configuring for LaserJet compatibility
• Using virtual font cartridges
The topics in this chapter help you find new uses for the printer, manage your consumable
supplies, and maintain optimum print quality.
Maintaining Print Quality
In some situations, print quality can be very subjective, and in other situations, the problem is
very obvious. This section provides guidelines for making correct diagnosis of the problem to
minimize incorrect and needless repairs.
Visual print quality analysis assumes you have maintained the printer according to the required
maintenance procedures and schedule. Chapter 5 provides the printer maintenance schedule
and procedures.
This section provides print samples, starting with a good quality print. The rest of the print
samples are flawed. The consumables that may be responsible for the flaws are included with
each sample, along with recommended corrective actions.
Print Quality Troubleshooting
If you are dissatisfied with the quality of your prints:
1. Complete all of the weekly maintenance tasks (see “Weekly Cleaning” on page 5-1).
2. Clean your printer thoroughly (see “Periodic Cleaning (When Replacing Drum)” on
page 5-5).
3. Check the quality of your prints.
Maintaining Print Quality
6-2 Advanced Topics
If you are still dissatisfied with your print quality:
1. Print several test pages of your typical work output and compare the print quality to the
samples.
The print samples provided here are generic, that is, they show specific problems. Your
own print samples are typical of your printout problems and so you must compare prob-
lem effects and not the actual print pattern.
2. Generate test prints to compare with the quality samples. (See Appendix E for more
information.)
3. Identify a print quality sample included in this section that has the same flaws as your
print test.
4. Review and complete the actions listed under the print sample in the order in which they
are listed, generating a print after you complete each action.
5. Check the print’s quality; if the flaw or flaws are still present, continue to the next action
in the list. If the flaws are repaired, you do not have to complete the remaining actions.
If you complete all the recommended actions, including changing consumables, and the print
quality doesn’t improve, you may need to call your service representative to resolve the
problem. Refer to “Where To Call For Help” on page F-1 for the telephone number of your
nearest Hewlett-Packard service representative. Be prepared to give the service representative
the error code and any messages that appear on the Control Panel to assist in troubleshooting.
Print Quality Problems
When you have any print quality problems, check the following items before starting your
troubleshooting:
1. Check the Control Panel for any messages about consumables. If there is a “Consumable
at end life” message, replace the consumable and retest for print quality.
2. Check whether the paper being used meets Hewlett-Packard standards. (Refer to “Using
Paper” on page D-1.)
3. Check whether the paper is handled correctly (especially for creases or wrinkles).
4. Check whether the environment for the printer and the paper meets Hewlett-Packard
standards - especially for humidity. Refer to Table C-5, “Printer environmental
specifications”.
5. Check whether the rollers and the paper guides are clean (especially for scattered toner
or developer, accumulated paper powder and paper pieces).
6. Check the Economode setting; be sure it is OFF. (See “Economode” on page 2-17.)
7. Adjust the print density. (See “Density” on page 2-25.)

All sample pages are shown in Letter size and portrait orientation. Similar problems may show
up on different paper edges, depending on the paper feed
Fading
If a white streak or a faded area appears on the page (in the
direction the paper passes through the printer):
• Check the Economode setting; be sure it is OFF. (See “Econo-
mode” on page 2-17.)
• The moisture content of the paper may be uneven, or there may
be moist spots on the paper. Print several dozen test pages with
paper from a newly-opened ream.
• The print density setting may be too light. Adjust the print den-
sity. (See “Density” on page 2-25.)
• Toner may be on the transfer charger or pre-charger corona
wires. Clean the printer’s transfer assembly unit and pre-
charger. (See “Transfer Assembly Guide” on page 5-9.)
• Replace the developer in the printer with new developer. (See
“Replacing Developer” on page 4-9.)
• Replace the drum unit with a new one. (See “Drum Kit -
Replacing Drum and Transfer Assembly” on page 4-18.)
• If you still have this print quality problem, contact your autho-
rized HP service representative.
Dropouts
If faded areas, generally rounded, occur randomly on the page:
• The moisture content of the paper may be uneven, or there may
be moist spots on the paper. Print several dozen test pages with
paper from a newly-opened ream.
• The paper lot is bad. The manufacturing process can cause
some areas to reject toner. Try paper from a different source.
• Clean the paper feed path and LED array as described in
“Weekly Cleaning” on page 5-1 and “Periodic Cleaning
(When Replacing Drum)” on page 5-5.
• Replace the developer unit with a new one. (See “Replacing

If the amount of background toner shading becomes unacceptable:
• The print density setting may be too high. Adjust the print den-
sity (See “Density” on page 2-25.)
• Toner may be on the transfer charger or pre-charger corona
wires. Clean the printer’s transfer assembly unit and pre-
charger. (See “Transfer Assembly - Transfer LED Areas” on
page 5-6.)
• Change the paper to a lighter basis weight.
• Check the printer’s environment; very humid conditions can
increase the amount of background shading.
• Replace old developer with fresh developer. (See “Replacing

authorized HP service representative.
Managing Consumables
Use the following checklist to identify actions you can take to maximize consumable yields.
Further detailed information is provided later in this section.
1. Keep the printer clean. Follow all the maintenance procedures listed in Chapter 5.
Accumulations of toner and paper dust affect the yields of all consumables.
2. Use high-quality media. Factors such as paper chemicals or scratches from unsupported
media can damage the drum and fuser. See Appendix A for a description of supported
media.
3. Handle all consumables and print media with care. Protect the drum from light and
abrasion. Avoid dropping or rough handling of consumables after they are removed
from their cartons. Store the consumables and media in a clean, stable environment,
preferably at the same location or under the same environmental conditions as the
printer.
4. Use the toner management features discussed on page 6-7. The D640 printer supports
several features that maximize toner usage.
5. Monitor and, if possible, manage print job sizes. Single-page print jobs are the least
efficient for consumable usage. Longer, multiple-page jobs are more efficient.
6. Monitor and, if possible, manage the complexity of printed images. Images which are
too complex to print at rated speed (for example, a large, complex PostScript image)
reduce the life of the drum and developer. Also, printing repetitive images can wear the
fuser rollers unevenly.
7. Avoid frequent lapses into power save mode or frequent power cycling. The start-up
process uses some of the life of the drum and developer.
8. Avoid prolonged periods of inactivity with the power switched on. Hewlett-Packard
recommends you switch off printers that are inactive overnight if the power save feature
isn’t used.
Managing Consumables
Advanced Topics 6-7
Advanced Topics
Note The factory yield estimates for consumables are determined under operating
conditions which are intended to model a large sample of customer installations. However, it is
impossible to model every operating environment, and as result some installations may
experience lower consumable yields than expected. Keep a log of actual consumable usage for
each printer. This provides the most accurate data to plan consumable purchases.
Toner
Toner yields are primarily driven by the quantity of toner applied to each page. Large black
areas, graphic images, gray backgrounds and forms outlines use more toner. If you print
mostly or only a small amount of text, you will probably reach or exceed the estimated yield.
Toner yield estimates are based on 4% toner coverage. This is a standard value used by the
printer industry, which is based on the assumption that the "typical" A4 or letter-size business
letter is 4% covered by black area.
The D640 offers a number of features that, with some trade-offs, can extend toner yield.
Density
The density value is factory set to 10, approximately in the middle of its range. The density
value can be set as low as 1 to reduce toner consumption. To the naked eye, solid area patterns
will not appear any lighter under lower settings. Reducing the density will have the largest
visual effect on gray scale patterns or the small text characters.
Experiment to see if a lower density value can satisfy your print quality requirements. Actual
toner savings will vary based on the types of images printed. The density setting can be found
under the Maintenance Menu, described in “Density” on page 2-25.
Economode
Most printers simply print a lighter pattern when an economode setting is used. However, the
D640 does not lighten the entire image. Instead, dots are turned off in strategic areas to reduce
toner use while maintaining readability. When printing text in economode, the character
outline is perfectly formed, while the inside uses fewer dots. The effects are nearly invisible to
the naked eye at a 10 point character size, but may be more readily seen on large characters.
Experiment to see if economode can be used for some, if not all of your printing. Large text-
only reports may be able to use economode with no perceptible reduction in print quality.
Economode can reduce toner consumption as much as 50%, depending on the printing pattern.
The Economode setting can be found under the Configuration Menu, described in
“Economode” on page 2-17.
Managing Consumables
6-8 Advanced Topics
Recycling
Printers that user powdered toner generally only transfer about 70 to 80% of the toner used for
a page image to the paper. The remaining 20 to 30% is known as waste toner because in most
printers it is thrown away. In a printer that uses a toner cartridge, the waste toner is never seen
because it is moved to a waste area inside the print cartridge.
The D640 printer is unique in the industry, providing the choice of recycling the waste toner or
throwing it away. As the printer ships from the factory, the toner recycling mode is disabled
and waste toner collects in a bottle. You remove and throw out this bottle each time you add a
new bottle of toner. With toner recycling enabled, the waste toner is funneled back into the
toner hopper and gradually mixed with new toner.
The disadvantage to recycling toner is a possible slight reduction in print quality. Print may
appear lighter and small voids may be visible in dark images. In most text applications, you
will probably not notice any reduced print quality with recycling on. If your application
requires the best possible print quality, do not use toner recycling.
Unlike Density and Economode, the effects of toner recycling are not immediately noticeable
when you stop recycling. The waste toner must be completely flushed from the toner path.
Depending on how long the recycling feature was used, it might take up to five bottles of new
toner before the waste toner is completely flushed from the system.
Toner Recycling Switch
Toner recycling is enabled or disabled by moving the plastic slide switch located directly over
the toner collector bottle. When it is pushed to the right, toner is recycled. When it is pushed to
the left, waste toner collects in the toner collector bottle for disposal. Figure 6-2 shows the
bottle and switch location.

Figure 6-2 Toner Recycling Slide Switch
Drum and Developer
The drum and developer are grouped together because their yields depend on drum rotations.
There is physical wear on the drum and developer mixture with every rotation of the drum.
The drum is often rotating even when the printer is not printing. Factory yield estimates for the
drum and developer, listed on the data sheet and in this manual, can never be accurate because
there is not a one-to-one correspondence between drum rotations and printed pages. However,
the internal counters in the printer do count drum rotations for both the drum and developer.
The drum life is estimated at 250,000 drum rotations and the developer life is estimated at
160,000 drum rotations.
The drum rotates during power up, at the start and end of each job, and while printing each
image. Knowing what factors drive drum rotations helps you understand what determines the
lives of your drum and developer.
Frequent power cycling or lapses into power save mode add wear to the drum and developer.
During power-up or coming out of power save mode, the drum rotates for up to two minutes.
This can produce as many as 80 drum rotations even though no pages are printed.
Toner Recycle Slide
Managing Consumables
6-10 Advanced Topics
The average number of pages in print jobs has a large effect on drum and developer life. Extra
drum rotations occur at the start and end of each job. There are four rotations at the beginning
and four rotations at the end. If the D640 primarily prints very small jobs (less than 25 pages),
you get lower than rated yields on the drum and developer. If you primarily print jobs larger
than 25 pages, you get higher than expected yields.
There is also a negative effect on drum rotations if you print complex images that slow the
printer down. If the printer controller cannot process the incoming data fast enough to keep the
printer running at 40 pages per minute, extra drum rotations occur for the print job.
The estimated yields for the drum and developer assume a job size of 25 page sides per job. It
is not important if you occasionally print small jobs or complex images; it’s important how
your print environment averages usage over a long period of time.
The drum surface is easily damaged by scratches, long exposure to fluorescent light (30
minutes), or exposure to direct sunlight (which may cause gray background shading). The
estimated yields do not account for replacement due to these factors.
Scratches can occur from unsupported media and may be significant enough to require the
drum to be replaced prior to the printer indicating the drum has reached its end of life.
Paper which emits certain chemicals or large amounts of paper dust can cause excessive drum
wear. If you this problem, contact your service representative or the paper manufacturer.
Fuser
The fuser yield is controlled by the number of times a letter or A4 sheet of paper passes
through it. The printer maintains a counter which increments based on the size of paper used.
Factors which may reduce fuser life can be related to printing repetitious images, media
problems or not replacing the cleaning roller when necessary.
Hewlett-Packard recommends mixing up the types and positions of print images printed
among print jobs. Fuser rollers can wear unevenly when a dark image, such as a company logo
or a thick dark line, is printed repeatedly in the same position on every page of every print job.
Media can also have an effect on fuser life. Paper which emits certain chemicals or large
amounts of paper dust can cause excessive wear. If you suspect problems of this sort, contact
your service representative or the paper manufacturer.
For optimum fuser life, replace the cleaning roller after every other bottle of toner, and follow
the recommended cleaning procedures in “Duplex Area” on page 5-6. The cleaning roller
deposits silicon oil onto the fuser roller surface to prevent toner from sticking. It also cleans
away small amounts of toner that adhere to the fuser roller surface. Failure to replace the
cleaning roller at the specified times can greatly reduce fuser yields.

Advanced Topics 6-11

Ozone Filter
The ozone filter is replaced after every two bottles of developer. If replaced as specified, you
should always receive the specified yield.
Transfer Unit
The transfer unit is replaced whenever the drum is replaced. Care must be taken to prevent
accidental breakage of the delicate wires located inside the transfer unit. Unless physically
damaged, you will always receive the specified yield.
Pushing Consumable Life Beyond Estimated Yields
The printer maintains counters to track all consumable use and provides an alert message to
inform you when a consumable item needs to be replaced. The printer will not stop, except
for lack of toner or developer, but the message remains until you replace the specified
consumable. There is a built-in "grace period", so the message to replace a consumable
should occur long before you see any print quality or paper jam problems.
When you get a "Toner Low" or "Developer end-life" message, it is best to add toner or
developer as soon as possible. If toner runs out completely, or the developer reaches its end-
life, the printer stops printing to prevent damage to the print engine.
Toner and developer are the only consumables for which the printer physically stops. If you
have a carefully monitored environment, you can watch the print quality and change the
consumables (other than toner and developer) only when absolutely necessary. This tactic may
further extend the replacement cycles of your consumables at your own risk.
Adjusting Paper Path Alignment
Over time, the paper path alignment may change slightly from the factory-set position. The
following paper path alignment procedure will set the printing alignment for each tray to
ensure correct print position. This procedure looks complicated, but after you have performed
it a once or twice, it should only take a few minutes to complete. It may need to be repeated
periodically to ensure proper alignment, but if you only print on blank paper, alignment is
usually not critical.
This procedure sets alignment for both simplex and duplex pages. If you have an HCI installed,
you can also set alignment for it.
Before proceeding, make sure that there is adequate (20 - 30 sheets) paper in each tray and the
HCI (if installed). This amount is necessary for accurate feeding.
Note Please read through the entire procedure before performing any of the
steps.

This procedure includes the following tasks:
• Printing alignment sheets. When you run the alignment program from the printer’s hard
drive, the printer produces a set of alignment pages.
• Measuring alignment. By measuring the current alignment for each tray against a
reference standard, you simply add two numbers to determine new alignment values.
• Setting alignment values. Once you have determined new values, enter them in the
Control Panel and recheck the alignment.

Setting Up Edge-to-Edge Printing
The D640 printer ordinarily enforces a 1/6" unprintable area around the edge of any page. This
is the factory default and produces the best looking output. There may be some cases where
you don’t want this border. The D640 supports edge-to-edge printing, which allows you to
extend printing to the edge of the physical page.
Note The print quality is not consistent within 1/6" of any edge. This is especially true for
the trailing edge of the second side in duplex printing. For this reason, Hewlett-Packard cannot
guarantee print quality within this 1/6" area. Your Hewlett-Packard warranty and service
contract does not cover service calls related to printing within this 1/6" area.
The quality and squareness of the paper determine print quality when printing close to the
physical paper edge. In general, you may experience degraded print quality within .25 inches
of any paper edge. When printing in duplex you may need to compensate for shrinkage and
curl that may occur when the first side is printed. Lighter weight and recycled papers tend to
shrink more then heavier weight papers.
If you define text to start printing at location 0,0 it will print outside the logical page. This may
or may not be on the physical page. Figure 6-18 describes the physical and logical page
formats.

Configuring for LaserJet IIIsi and 4si Compatibility
6-24 Advanced Topics
Configuring for LaserJet IIIsi and 4si Compatibility
The D640 printer is unique and different from the Hewlett-Packard LaserJet family of printers
in general, and from the LaserJet "si" series in particular. While these two printer families
share the same printer language (PCL and PJL), there are a number of physical differences to
their hardware.
We have included features in the D640 printer to make it behave like a LaserJet 4si, so your
print jobs turn out like you expect. In many instances these features also provide compatibility
with the LaserJet IIIsi and/or 5si.
This section covers the compatibility features associated with PCL commands.
Paper Input
The D640 has three paper input trays, while the LaserJet 4si has two. The LaserJet5si has
three.
HCI selection compatibility is provided through the HCI-Alias Control Panel setting. HCI-
Alias enables paper selection compatibility between a LaserJet IIIsi or 4si with an HCI and a
D640 with an HCI. You can also set HCI-Alias = HCI to pick paper from tray1, tray2, tray3, or
the HCI in response to the PCL commands shown in Table -6-1, “Paper tray map for HCI-
Alias = HCI”.
Example Configuration
LaserJet IIIsi / 4si
• UPPER TRAY contains paper for job separation.
• HCI TRAY contains white paper.
- This configuration provides 500 sheets in the upper tray and 1500 sheets in the HCI
tray. To match this configuration on the D640, set up the D640 as follows:
• TRAY1 contains paper for job separation.
• HCI contains white paper.
• Set HCI-Alias = tray2.
- This configuration provides 500 sheets in tray1 and 3000 sheets in the HCI. You could
also load paper for job separation in tray2 and tray3 to increase capacity to 1500 sheets.
Configuring for LaserJet IIIsi and 4si Compatibility
Advanced Topics 6-25
Advanced Topics
If HCI-Alias is set to HCI, the values shown below in Table -6-1, “Paper tray map for HCI-
Alias = HCI” are correct. If HCI-Alias is set to tray2, then you can send a job to either a 4si or
a D640.
Table 6-1 Paper tray map for HCI-Alias = HCI
You can also set the default paper tray (used if there is no paper size or paper source command
embedded in the print job) from the Control Panel. Use the intray setting in the Printing Menu.
Using the LaserJet 5Si Driver
The D640 printer can be used with a LaserJet 5Si printer driver, but there are many differences.
For example:
• The input tray selection is different. See Table 6-1 above.
• The D640 printer does not support media type selection.
• The LaserJet 5Si does not support font cartridges.

lower tray middle tray (tray2) lower drawer (tray3)

Using Virtual Font Cartridges
6-26 Advanced Topics
Using Virtual Font Cartridges
Each of the D640 internal fonts is almost identical to those used in the LaserJet 4si. Some
typefaces, treatments, and symbol sets are slightly different, due to advances in font
technology since the development of the 4si. For example, if you print a very large question
mark on each machine, you may notice differences in the shape.
All of the font sets from all of the 4si font cartridges sold by Hewlett-Packard are stored on the
D640’s internal hard disk drive as virtual font cartridges. You select the virtual font cartridge
by the Control Panel vcartridge1 and vcartridge2 settings (see “Virtual Font Cartridges” on
page 2-20). The font names are comparable to the actual physical cartridge.

Host Serial and Parallel Interface Configuration
Introduction
The D640 printer is equipped with two standard communication interfaces used to connect to a
host computer:
•Bitronics (Parallel) interface
•RS-232C serial interface
With the addition of an HP JetDirect EX interface, purchased separately, you can use the
printer on a local area network (LAN). The JetDirect EX interface connects the network to the
Bitronics interface of the printer. (If you purchased the HP JetDirect EX interface, you’ll find
detailed directions included in the JetDirect EX Configuration Guide.)
Figure B-1 Standard Signal Interface Connectors
The standard parallel (IEEE 1284C) and serial (RS-232C) communication interface connectors
are located on the back of the printer, as shown in Figure B-1. The IEEE 1284C connector is at
the upper back of the printer; this connector is smaller than the usual (Centronics) parallel
Serial connector
Parallel connector
Using the Serial Interface
B-2 Host Serial and Parallel Interface Configuration
connector. This is a “C” type Bitronics connection. Hewlett-Packard has included an “A-to-C”
parallel printer cable with the printer. The RS-232C connector is the standard DB25 pin
connector, located near the top center of the printer.
You can get more information about HP’s compliance with the IEEE 1284 Standard from the
HP FIRST fax retrieval service at 1-800-333-1917 in the USA and Canada. Ask for document
number 1951. The same document is also available by ftp from:
ftp://ftp-boi.external.hp.com/pub/printers/laserjet/doc/bp02455.asc
Using the Serial Interface
Use the serial interface when you need to locate the printer at some distance (up to 50 feet (15
meters)) from the host computer. You can use either an RS-232C or an RS-422A cable.
Table B-1 lists RS-232C and RS-422A pin assignments and signal descriptions. Those pins not
listed in the table are not used.

Interface
Configuration
The serial interface is accessible through a 25-pin female connector (Figure B-2) at the back of
the printer.
The interface can be configured to operate in an RS-232 or RS-422 configuration. Use the
control panel to set the configuration.
If you are set up for RS-232 operation, you can convert to RS-422 operation by shorting pin 14
of the interface to ground (pin 7).

Using Paper
The D640 prints on a variety of print media, including paper, labels, and overhead
transparencies, at up to 600 x 600 dots per inch (dpi).
Note The D640 does not accept envelopes as print media.
The D640 printer uses laser electrophotographic technologies. In this process, a laser writes an
electrostatic image onto the photosensitive drum. As this image passes the developing station,
a dry, powdery toner is attracted to the imaged areas. This developed image then advances to
the transfer station, where the belt contacts the media and the toner image is electrostatically
transferred onto the paper. After transfer, the media passes through the fuser; heat and pressure
are applied and the toner fuses (melts) onto the media. The media is then deposited in the
output tray, ready for use.
To create the printed image all print media must be transported through the printer,
electrostatically charged, and heated. This is why media properties such as electrical
resistivity, caliper, smoothness, and stiffness can affect the print quality and media handling
performance of your D640 printer.
Supported Print Media Types
Your D640 printer will print on a variety of media, including paper, labels, and overhead
transparencies. “Media Selection Specifications and Guidelines” on page D-3 provides
suggestions for these different media.
Hewlett-Packard neither warrants nor recommends the use of a particular print media. Media
properties are subject to change by manufacturers and Hewlett-Packard has no control over
such changes. The customer assumes all responsibility for the quality and performance of
media. Although testing media helps to characterize their performance, long-term satisfaction
requires process quality control by the manufacturer and proper handling until use.
Alternate Sources of Information
The manufacturer and the vendor of the media that you select should be able to provide
information about the suitability of its use in a D640 printer. Your vendor should be your
contact when selecting media for your individual application needs. If you have tried all of the
suggestions outlined in this document, and still need assistance, HP provides support through
the world-wide network of Hewlett-Packard Sales and Service Offices. Refer to “Warranty and
Support” on page F-1.

In the United States, Hewlett-Packard also offers support through a local support
representative. A customer support technician will be happy to offer advice to help solve your
printer operation problems.
Paper Manufacturing
Laser printers require paper types and specifications that were uncommon just a decade ago.
Until then, no distinction was made between writing paper and xerographic paper. The
manufacture of paper is complex. Several different mills may offer the same type of paper (for
example, 25% cotton bond, writing stock) but each manufacturer will vary the texture, color,
fiber, lignin, coating, and other elements which make their product unique. In the paper
industry, there are no equivalent papers between manufacturers, only substitutes.
Sources of Paper
Paper is primarily made from cellulose fiber, the major component of the cell walls of wood
fibers and other plants. Sources of this fiber include:
•Raw Wood
•Recycled or waste wood
•Cotton
Pulping methods are based, in part, on the fiber length of the raw wood. Hardwoods, such as
cottonwood, contain short fibers, from one to two millimeters in length. Softwood fibers,
including pine, spruce, and other conifers range in length from three to six millimeters. In each
case, the thickness is less than that of a human hair.
These differences often mean variability among paper manufacturers, even within the same
company. To ensure quality and consistency, a certain percentage of this material must come
from raw wood. Timber may be harvested from national forests and private land as well as tree
farms or plantations.
Surface Coatings
A thin layer of coating may be applied to the paper which could change its physical
characteristics. These surface coatings or “sizings” are added to make the sheets more resistant
to ink or water penetration and to increase durability. Coatings may also be added to create a
neutral pH in paper used for archival storage (such as legal documents). Surface coatings are
usually liquid starches and are applied either by spraying, immersion, or mixing into the
furnish.
Heavy coatings of clay or talc should be avoided because they become hard and brittle, causing
the fibers to break like a piece of chalk and come off during printer operation. Surface coatings
also affect the surface electrical resistivity, which is a important factor in the performance of
your D640 printers.
Media Selection Specifications and Guidelines
Using Paper D-3
Using Paper
Cast Surfaces
When a very smooth surface is required, a clay and water solution is applied to the paper, and
is then “cast” under high temperatures. Cast surface paper is mainly used for offset color
presses and making original typeset master sheets used in publication printing. This type of
paper is not recommended for D640 printers because clay is very abrasive to components in
the paper path.
Packaging
Packaging is an important step in the paper-making process. Much of the paper used for
computing printing applications is packaged in reams: wrapped bundles containing 500 sheets.
Because paper is hygroscopic, or capable of absorbing or losing moisture from the air, it
should be protected by moisture-proof polylaminated wrapping and moisture barriers. A ream
of finished paper usually contains about 4% moisture. The paper ream remains stable if
properly stored and opened only when ready to be used.
Paper Ream Label
A ream label is placed on the outside of the paper wrapping. The ream label usually indicates
paper: basis weight, size, number of sheets, grain direction and grade. The printing surface of
the paper may be indicated by an arrow on the ream label. Paper should be loaded into the
printer so that surface indicated by the arrow will be the printing surface. The printing surface
may be up or down, depending on the printer model and the paper feeding source.

Recommendations to the Customer
Hewlett-Packard D640 printers are designed to be as flexible as possible in the types of print
media they can use. Since there are many varieties of media and variations in the
manufacturing process, you should test a particular medium in your environment to determine
if it performs acceptably.
Buy Media that Meets Specifications
To get the best performance from your D640 printer, select high quality print media that meet
the guidelines and specifications in this document.
Test Small Amounts of Media
The next step in choosing media, particularly if you are planning a large purchase, is to print a
small quantity in your environment. Subject it to the temperature, humidity, and printing
application in which it will be operating. DO NOT purchase large quantities without first
testing the media! Hewlett-Packard recommends that you ask your media vendor for a
guarantee that their media will perform satisfactorily in your D640 printer, and that you ask the
vendor to assume responsibility for the replacement of any media that will not print
acceptably.
Use High Quality Media
Hewlett-Packard printers will work best with high quality media. Quality media for D640
printers are characterized by uniform physical properties, freedom from dust and lint, accurate
cutting to size, and packaging that protects it from moisture and physical damage. Curled or
bent edges, spots, dust or lint, wrinkling, and inaccurate cutting to size are common media
problems that should be avoided. These problems can cause misfeeding, jamming, premature
wear, or unsatisfactory print quality.
Size
Table D-1, “Paper sizes” shows paper sizes that can be used with D640 printers. Shown also is
the numeric code displayed on the operator panel for each paper size. All paper sizes can be
used in either simplex or duplex printing modes. Use only paper that is within the dimensions
shown in Table D-1, “Paper sizes”.
Note Although the D640 printer can print over the entire sheet, we do not guarantee quality
for print in the outer 5mm of the page periphery. This border will vary slightly with the quality
of the paper used.

Basis Weight
Basis weight is an important characteristic to consider because, paper that is too light or too
heavy may cause misfeeds, mis-stacking, paper jams, or excessive mechanical wear.
The printer is specifically designed to perform at maximum efficiency when 20 pound bond
(75g/m2) paper is used. Optimum print quality and paper path reliability are achieved when
high quality electrophotographic (EP) paper is used. EP papers have specific characteristics
that distinguish them from bond papers. The range of paper weight that the printer and HCI can
process is 17 to 24 pound (64 to 90 g/m 2). The printer can handle paper weights up to 36
pound (135 g/m2), but 17 to 24 is optimum.
Specifications for basis weight depend upon the paper source the paper is fed. In general, the
straighter the paper path, the heavier the basis weight may be. For more complex paper paths,
as in feeding from the HCI, a lighter weight may be required, in range of 18 to 24 pound.
Furnish (Composition)
Furnish is the fiber and chemical composition of paper. Fiber composition of the paper used in
D640 printers should be manufactured from 100 percent chemical wood pulp and/or cotton
fiber. To ensure that paper of a special fiber composition will work properly, always test it
before purchasing large quantities. Other allowable components of paper are sizing, fillers,
buffers and pigments.
Note DO NOT use coated paper or paper containing materials that melt, vaporize, offset,
discolor or release hazardous emissions when exposed to 392°F (200°C).

D-6 Using Paper
Curl
Curl is curvature in a sheet of paper. Curl is typically measured by laying the sheet of paper on
a flat surface, with the corners up, and measuring the height of the corners. In-ream curl is the
amount of curl a sheet of paper has before printing. (In-ream curl may result from the paper
manufacturing process or from exposure to the environment). Post-image curl is the amount of
curl a sheet of paper has after printing (from exposure to the fusing process and paper path in
the printer). Paper with excessive in-ream curl may lead to feeding and print quality problems.
In addition paper with excessive post-image curl may be difficult to handle or use in
automatic-feed photocopiers.
The curl side of the paper can be identified by a slight concave bowing from the outside edges
of the paper stack towards the center of the top sheet. This curled side is always the side that
should face away from the printer’s photoconductor. Having the curl side face away from the
photoconductor helps the paper separate from the photoconductor surface during the printing
process.
Paper curl becomes more obvious after fusing of a print. If the curl of a printed page appears
too excessive, it is likely that paper handling problems may occur during duplex printing. If
this is the situation, open the paper tray and turn the paper over. Try printing again. If the
problem is still not resolved, select a different paper for duplex printing, and reserve the
“problem” paper for single-sided printing.
Besides paper handling problems, excessive curl may also result in blurred print and similar
print quality problems. The HP standard for in-ream paper curl is no more than 0.2 inches
(5 mm) on any part of the paper, with 0.1 inches (3 mm) the optimal value.
Finish (Texture)
Finish, or texture, is the degree to which the surface is free of irregularities (or the smoothness
or roughness of the paper). Using paper that meets HP specifications for surface texture is
critical to the operation of D640 printers. The degree of surface texture is determined by the
fiber composition of the paper, fillers which may have been added to the paper mixture, and
the number of passes through the calendar stacks. Common paper textures included
cockleshell, linen and laid.
Media Selection Specifications and Guidelines
Using Paper D-7
Using Paper
Potential Problems
Some textures improve paper feeding while others hinder the feed operation. Too smooth or
too rough paper can cause a variety of problems in D640 printers.
Felt Side vs.Wire Side
The way paper is manufactured results in two-sided paper properties. This, along with other
process variations, may make one side of the paper the preferred side to print on. The “top”
side of the paper sheet as it is formed is known as the felt side, and the “bottom” is known as
the wire side. Most manufacturers indicate the preferred printing side on the package.
Moisture Content
Note Moisture content is the most critical factor in paper performance in D640 printers. The
moisture content of most paper at the time of manufacture is about 4-6% of volume by weight.
This percentage can be altered as a result of environmental conditions during converting
processes, shipping, storage, and printing.
Storage, especially over long periods, can greatly influence moisture content. Because of the
hygroscopic properties of paper, unless proper humidity and temperature are maintained, the
paper will lose or gain moisture.

D-8 Using Paper
The environmental conditions required to maintain the proper moisture content is 68°F to
75°F (20°C to 24°C) with a relative humidity of 45% to 55%.
The HP standard for moisture content is 4.7% ± 1% by weight. Although a paper may have the
proper moisture content at the time of manufacture, exposure to temperature and humidity
extremes may alter the percentage.
Fusing Compatibility
Media that does not meet HP specifications may:
• Discolor
• Melt
• Scorch
• Offset
• Release hazardous emissions
• Have poor toner adhesion
• Break down in other ways
• Possibly damage the printer
All media used in D640 printers must have the ability to withstand the fusing temperature of
392°C/200°C for 0.1 second, without experiencing any problems.
Inspect the rollers for colored ink build-up from pre-printed logos or letterhead and for toner
buildup or spots. Inspect printed output for repetitive defects and smearing. If necessary,
contact your forms vendor to ensure paper’s fusing compatibility with D640 printers.
Table D-3 Moisture content potential problems
Too Moist •Paper shrinks unevenly during fusing, causing print quality problems
•Overall paper curl increases (increases post-image curl, causes poor toner
adhesion, feed and print quality problems)
Too Dry •Excess static (causes multi-feeds and paper jams)
•Surface electrical resistivity (causes streaking and smudging of loose toner
particles)

General Guidelines
Some general guidelines to follow when selecting media are summarized on the following
pages.
Use conventional white xerographic paper for most printing. The paper should be of high
quality, free of cuts, tears, grease spots, loose particles, dust, wrinkles, voids, and curled or
bent edges. Xerographic papers, also called photocopy or xerocopy papers, are usually made
from chemical wood pulp and are characterized by a smooth surface, controlled electrical
properties, heat stability, and cleanliness. These characteristics ensure good image transfer,
fusing without excessive curl, and reliable printer operation.
Some applications may require a paper having a more prestigious look or feel. Bond papers
generally have a watermark and often use cotton fiber. These papers tend to have a rougher
surface and their properties may not be controlled like xerographic papers. However, your
D640 printer will print satisfactorily on many of these bond papers. Also, some paper
manufacturers are now making laser grade bond papers which have properties compatible with
laser quality printing.
One of the most important things you can do to ensure the best possible performance from your
D640 printer is to select a quality paper. Table D-4, “Recommended paper specifications”,
summarizes the specifications of a paper that will give you the best performance.

Using Paper
Pre-printed Forms and Letterhead
To avoid multiple feeding and jamming problems when using pre-printed forms, embossed
paper, and letterhead, observe the following guidelines:
•Do not use low-temperature inks (the kind used with some types of thermography).
•Use forms and letterhead printed by offset lithography or engraving.
•Forms must be printed with heat-resistant inks that will not melt, vaporize, or release
hazardous emissions when heated to 392°F (200°C) for 0.1 second. Typically, oxidation-
set or oil-based inks meet this requirement.
•If oxidation-cured inks are used, the use of oxidation retardants should be minimized.
•When the form is pre-printed, be careful not to change the moisture content of the paper,
or use materials that change the paper’s electrical or handling properties. Forms should be
sealed in moisture-proof wrap to prevent moisture changes during storage.
•Pre-printed forms should not be processed with a finish or coated at the end of their
production.
•Do not use heavily embossed or raised letterhead papers.
•Avoid papers with heavily textured surfaces.
•Avoid using a band of ink on the leading edge of the paper.
•Water additives must not be used, as they change the conductivity of the paper. The effect
of the electrical charge applied to the paper during the printing process may be altered.
•Following offset printing, the printed pages should be allowed to dry for one to two weeks
in an atmosphere of 60°F to 80°F (16°C to 27°C) with a relative humidity of 35% to 50%.

Adhesive Labels
For the purposes of this specification, a label is defined as paper with a pressure-sensitive
adhesive backing. Label stock includes the top or face sheet, the adhesive, and the liner or
carrier sheet, also referred to as the backing.
Note the following points about label stock:
•Top or face sheets: The top sheet, which is the printing surface, is usually composed of
xerographic paper. Label top sheets must provide good toner adhesion.
•Carrier sheets: The carrier sheet must be compatible with the temperatures and pressure of
the fusing process, and must be coated for easy release of the top sheet.
•Adhesives: The adhesive must be stable at the 392°F (200°C) temperatures encountered in
the printer's fusing process, and must not produce emissions that exceed exposure levels or
threshold limits established by OSHA and other safety agencies. Adhesives must not come
in direct contact with any part of the printer. No adhesive should be pressed out of the
edges or between die-cuts (the cuts between individual labels).
• Label arrangement: Labels should be arranged on the carrier sheet so that any exposed
spaces run lengthwise down the sheet (See Table D-5, “Label specifications”.) Using label
stock with spaces between the horizontal rows of labels can often result in labels peeling
off during printing, causing serious jamming and possible printer damage.
Labels may be specially manufactured to leave a margin around the outside edges that
correspond to the outer margins of the printable area. If this special arrangement is to be used,
DO NOT REMOVE the excess top sheet material from the carrier sheet.

General Guidelines
Using Paper D-13
Using Paper
Note It is possible that labels could meet all of the general specifications listed in "Adhesive
Label arrangements" and still not print satisfactorily because of the printing environment or
other variables over which Hewlett-Packard has no control.
Note The following actions can cause labels to peel off, possibly damaging the inside of
your printer: printing on labels while the printer is in duplex mode or removing individual
labels from the carrier sheet, then printing on the remaining labels.
Note Hewlett-Packard does not recommend removing any labels from the carrier sheet and
then printing on the remaining labels. If labels must be removed, remove them from the bottom
of the carrier sheet, continuing toward the top.
Note Overhead transparencies used in D640 printers must be able to withstand the 392°F
(200°C) temperature encountered in the printer's fusing process.
Specifications for overhead transparencies are summarized in Table D-6, “Overhead
transparency specifications summary”.

Recycled Paper
Recycled paper is a combination of waste paper, pre-consumer waste, and post-consumer
waste. Printed waste paper is usually washed to remove most of the inks and other
contaminants. A recycled sheet of paper may contain dark specks or appear gray or dirty. You
should choose a recycled paper that meets the same specifications (except perhaps brightness)
as standard paper, and has an appearance suitable for your needs. Hewlett-Packard
recommends that the recycled paper contain no more than 5% groundwood.
Note Depending on the quality of recycled paper, you may experience a higher jam rate and
reduced consumable life compared to equivalent quality non-recycled paper.
Archival Paper
Paper used for archiving must meet the same specifications as standard paper, however, the pH
should be no less than 7.0. Some archival demands are more stringent than others, requiring
the degree of alkalinity and chemical stability to be specified.
Toner is chemically stable and should last as long as the paper does. Toner can be degraded by
petroleum based solvents or plasticizers, such as those found in vinyl folders. Avoid folding
archival documents across printed areas or handling them roughly. Discuss archival
requirements with your paper supplier.
Colored Paper
Colored paper can be used in D640 printers as long as the standard paper specifications are
met.

General Guidelines
Using Paper D-15
Using Paper
Paper with Cutouts or Perforations
Hewlett-Packard does not recommend using paper with cutouts or perforations because they
often cause paper handling problems and may cause printer damage.
A cutout is defined as any portion of the paper that has been removed, including binder holes,
notches, square cuts, etc.
Paper with internal perforations may cause misfeeds and paper jams.
If you must use papers with internal perforations or cutouts, take care to conform to the
following:
•Cutouts and perforations should be punched from the side to be printed on, so that edge
trimmings will not scratch the photosensitive belt.
•Do not print at a cutout location, or closer than 1/8 inch (3.5 mm) to the edge of a cutout,
to prevent toner from contaminating the inside of the printer.
•Cutouts and perforations should be cut clean (without burrs), to avoid multiple feed,
contamination problems, or paper jams.
•Avoid perforations that run perpendicular to the paper path. When the printer transfers
paper from one set of rollers to the next, a perforation can cause the page to bend
downward and miss the pickup point on the next roller.
Chemically Treated Paper
Coatings such as lacquers, polymers, laminations or other chemicals protect the paper but can
cause problems in the fuser and transfer areas of D640 printers. The surface resistivity and
moisture content can be greatly altered, resulting in print quality problems. Hard surfaces
coatings increase wear on the rollers and paper guides. All chemically treated paper must meet
HP specifications for fusing compatibility.
Synthetic Paper
Synthetic papers (those manufactured from man-made fibers) do not perform as well as bond
papers in any printer, especially D640 printers. Each type has its own problems which result in
poor feed and print quality performances. All synthetic papers must follow HP specifications,
especially for caliper and fusing compatibility. Be cautious about heat-generated fumes which
may be dangerous to breathe.
Coated Paper
Do not use papers where a coating has been added after the paper is produced. Most coated
paper does not meet specifications for fusing compatibility, as well as all other specifications
for D640 printers.

an appearance suitable for your needs. HP recommends that recycled paper contained no more
than 5% groundwood.
Things to Avoid
DO NOT attempt to print on any of the following:
•Extremely shiny or glossy paper.
•Very rough, textured, or embossed media.
•Multipart forms or carbonless papers.
•Media, media coatings, dyes, or inks that produce hazardous emissions or melt when
exposed to a fusing temperature of 392°F (200°C).
•Media that offsets or discolors.
•Media with folds, staples, paper clips, etc.
•Damaged, curled, wrinkled, or irregularly shaped media.
•Letterhead paper produced using low temperature dyes or thermography.
•Paper containing large amounts of clay or talc.
•Media that have already been printed with a photo copier or a D640 printer.
•Low quality recycled paper.
Purchasing, Handling, and Storing
The performance of D640 printers is dependent on the condition of the print media used. This
section contains recommendations for purchasing, shipping, handling and storing media.
Acceptable paper can be purchased from your local supply house. Ask your vendor to verify
that the paper will work acceptably with a D640 printer.

D-18 Using Paper
Storing
Adhere to the following guidelines when stacking and storing print media:
•DO NOT store cartons of reams directly on the floor; cartons should be placed on a pallet
or on shelves.
•DO NOT store individual reams in such a manner that they will curl or warp along the
edges.
•Rewrap partially used reams of paper before storing.
•DO NOT stack more than six cartons high.
•Stack each carton squarely on top of the one underneath.
•Stack each carton upright.
•DO NOT place anything on top of paper, regardless of whether the paper is packaged or
not.
•Store envelopes in a protective box so the edges will not be damaged.
•Keep stored media away from extremes in temperature and humidity.
•DO NOT store printed documents in vinyl folders (which may contain plasticizers), or
expose the documents to petroleum based solvents.
Environmental Considerations
Media should be protected from temperature and humidity extremes. D640 printers are
designed to operate in a wide range of environmental conditions, but for best performance,
media should be stored and used at 59°F to 95°F (15°C - 35°C), with a relative humidity of
40% to 60%.
When media are used in an environment outside the ranges of temperature and humidity shown
above, follow these guidelines:
•DO NOT leave the media exposed to humidity or temperature extremes. Any extreme
changes in the environment will cause the media to take on unwanted characteristics if left
unwrapped or in the input tray of the printer.
•Where humidity extremes occur, store paper in an airtight container, or seal it in plastic.
•If there is a significant temperature difference between the media storage area and the
printer’s operating environment, allow the media to adjust to the temperature in the
printer’s operating environment before unwrapping. The greater the temperature
difference and the greater the amount of media to equilibriate, the longer this time period
should be. Allow one day for every 20°F (10°C) difference in temperature between
storage environment and printing environment.
Paper is affected by temperature and humidity variations during transport, storage, and use.
When the atmosphere is moist, paper tends to have wavy edges; conversely, when the
atmosphere is dry, paper tends to have wavy centers.
Purchasing, Handling, and Storing
Using Paper D-19
Using Paper
Acclimatizing paper to the “best performance conditions” described above minimizes these
adverse affects, but exposure to temperature and humidity extremes will eventually make
acclimatization impossible. In extreme conditions, the paper may become unfit for use. For
optimum results, keep paper supplies in moisture-proof packaging and load only the amount
that will be used soon.
Printer Normal Operating Environment
The specifications for the printer's operating environment are defined below. Observing these
environmental guidelines helps ensure trouble-free printer operation.The temperature and
humidity of the paper used with the printer should be in balance with the printer's environment.
•Temperature 59°F to 95°F (15°C to 35°C)
•Relative Humidity 20% to 80%
•Altitude 0 to 7000 feet (0 to 2150 m)

Troubleshooting
D-20 Using Paper
Troubleshooting
Paper problems are somewhat difficult to detect. A series of steps will help isolate paper-
induced problems. The steps to follow are:
•Is it a paper or a printer problem?
•Isolate a paper path
•Isolate a paper brand
•Isolate a paper type
•Evaluate user’s paper practices
•Evaluate environmental conditions
Is it a Paper or Printer Problem?
When determining a printer failure, a distinction must be made between problems relating to
the printer itself and those involving paper. Often a problem which first appears to be related to
the printer is actually a matter of poor paper selection or handling. To determine is a problem is
printer or paper-induced a few simple steps can be helpful:
•Turn paper over in the tray to print on the reverse side.
•Rotate sheets 180° (end to end) to feed with a different leading edge.
If the symptoms cease, or change in some way, it can be assumed that the problems are paper
induced.
Isolate a Paper Path
The physical properties and composition of a particular paper influence its motion along a
printer’s main paper path. As a general rule, the straighter a paper path, the more forgiving it is
of the paper’s physical characteristics.
Try Using the Straightest Paper Path
Some problems can be avoided by using the straightest paper path. Feed paper from tray1. This
path is recommended for transparencies and heavy basis weight media.

Troubleshooting
Using Paper D-21
Using Paper
Determine if the Problem is Due to Duplexing
The duplexing feature may have both paper feed problems and print quality problems as a
result of printing on paper that has just made a pass through the printer (resulting in increased
paper curl). This paper curl increases image dropout, and pickup and stacking problems. The
second pass is made with paper which may no longer meet the specifications for moisture and
curl. Dry paper may not hold static charges which affect print quality and stacking. Image mis-
alignment front-to-back on a duplexed page may be caused by paper shrinkage.
Isolate the Source From Which the Printer Jams
Where was the paper being fed from? Possible sources include:
•Tray1, Tray2, Tray3
(500 20 pound paper sheets each)
•High Capacity Input Unit
(3000 20 pound paper sheets)
Where Does the Jam Occur?
Check where paper stops when a jam occurs. Types of jams that can occur include:
•Input paper jams
•Internal paper path jams
•Output jams
Is the Printer is Experiencing Multi-feed Jams?
The following are some possible causes in multi-feeds.
•Paper may be too light or too thin. Check the basis weight and caliper.
•Paper may be too smooth or too rough. Check the finish.
•Paper may have too much curl. Measure paper curl and check moisture content.
•Paper may have bad edge cuts or edge welds. Observe the cut edge condition.
•The customer may be attempting to print embossed paper, pre-printed forms, or perforated
paper which does not meet HP specifications. (See the following section,"Isolate a Paper
Type", for details about the difficulties of embossed paper.)
•Paper may be loaded incorrectly. Turn over the sheets in the paper tray to determine if in-
ream curl is the cause of misfeeds.
•Customer may be fanning paper before loading it into the paper tray.
•Customer may be adding paper in small amounts. Do not add small amounts of paper or
mix types of paper in the tray.
•The printer or paper storage environment may be too humid or too dry. (As a result, paper
may be too moist or too dry). Determine if this is the case and advise the customer.
Troubleshooting
D-22 Using Paper
Is the Printer Experiencing Misfeeds?
The following are some possible causes in misfeeds.
•Paper may be too stiff. Check basis weight and measure caliper.
•Paper may be too smooth or too rough. Check the finish.
•Paper may be too heavy or too light. Check the basis weight.
•The customer may be attempting to print embossed paper, pre-printed forms, or perforated
paper which does not meet HP specifications. (See the following section, "Isolate a Paper
Type", for details about the difficulties of embossed paper.)
•Paper may be loaded incorrectly. Turn over the sheets in the paper tray to determine if in-
ream curl is the cause of misfeeds.
•Customer may be fanning paper before loading it into the paper tray.
•The printer or paper storage environment may be too humid or too dry. (As a result, paper
may be too moist or too dry). Determine if this is the case and advise the customer.
Isolate Paper Brand
If the printer jams with only one brand of paper:
•If the paper ream being used appears to be old, open a fresh ream of the same paper and
load it properly into the printer. If the problem is remedied, investigate storage and
handling conditions.
•Do not purchase more paper than you can use in a short time (3 months). Paper stored for
longer periods may experience heat and moisture extremes which can damage it. Planning
helps prevent damage to your paper supply.
•If the problem persists, try switching paper brands.
Isolate a Paper Type
When paper jams and other problems occur frequently, it is often because special paper is
causing the difficulty. Use only paper that conforms to all HP specifications, and always test
paper before purchasing large quantities. If future problems occur, the cause may be easily
isolated to storage or handling conditions.
Some types of media that may cause problems are:
•Pre-printed forms and special letterhead
•Embossed paper
•Perforated paper
•Adhesive labels
•Envelopes
•Transparencies
•Chemically treated paper
Troubleshooting
Using Paper D-23
Using Paper
•Synthetic paper
•Coated paper
•Other special media
Refer to Table D-4, “Recommended paper specifications,” on page D-10 for a table of
recommended media specifications.
Printer Maintenance
General cleanliness of the printer is the most important part of printer maintenance. Good
maintenance improves the performance of any printer. Papers which create a lot of dust and
debris in the printer require a more aggressive maintenance schedule.
Areas which builds up paper dust heavily are:
•pick-up rollers
•paper guides
Taking extra time to clean and inspect the paper path results in fewer paper jams and cleaner
print. If problems continue after cleaning, inspect for wear or damage.
Paper Stacking
Consider the following guidelines when advising the customer about stacking paper:
•Do not store cartons of reams directly on the floor; cartons should be placed on a pallet or
on shelves.
•Do not stack more than six cartons high.
•Stack each carton squarely on top of the other.
•Stack each carton upright.
•Do not store individual reams in such a manner that they will curl or warp along the edges.
•Do not place anything on top of paper, whether it is packaged or unpackaged.
•Do not place paper close to heating or air conditioning vents or open windows.
Evaluate Environmental Conditions
Printing Environment
Ideally, the printing environment should be at or near room temperature, and not too dry or too
humid. Remember, paper is hygroscopic; it absorbs and loses moisture rapidly.
Heat works with humidity to damage paper. Heat causes the moisture in paper to evaporate,
while cold causes it to condense on the sheets. Heating systems and air conditioners remove
most of the humidity from the room. As paper is opened and used, it loses moisture, causing
streaks and smudging. Humid weather or water coolers can cause the humidity to increase in a
room. As paper storage is opened and used it absorbs any excess moisture, causing light print
and dropouts.
Troubleshooting
D-24 Using Paper
Paper Storage Environment
Paper storage and handling is as important as the paper-making process itself. Paper storage
environment conditions directly affect the feed operation.
Do not purchase more media than you can use in a short time (3 months). Paper stored for long
periods may experience damage from heat and moisture extremes. Planning is important to
prevent damage to a large supply of paper.
Unconverted paper in sealed reams can remain stable for several months before use. Converted
papers have more potential for environmental damage, especially if they are not wrapped in a
moisture-proof barrier.
Maintain paper in a storage environment of 59° to 95°F (15° to 35°C), with a relative humidity
of 40% to 60%.
•Paper should be stored at or near room temperature.
•The air should not be too dry or too humid (due to hygroscopic properties of paper).
•The best way to store an opened ream of paper is to re-wrap it tightly in its moisture-proof
wrapping. If the printer environment is subject to extremes, unwrap only the amount of
paper to be used during the day’s operation.

HP Maintenance Agreements
Hewlett-Packard has several types of maintenance agreements that meets a wide range of
support needs.
On-Site Service Agreements
To provide you with the support level best suited to your system usage and support budget, HP
has on-site service agreements with two response times:
Priority On-Site Service is designed for production-critical applications, giving you four-hour
service response to your site for calls made during normal HP business hours.
Next Day On-Site Service provides on-site support by the next working day following your
service request. Extended coverage hours and extended travel beyond HP designated service
zones are available for additional charges on most on-site service agreements.
HP5000 Model D640 Warranty
This warranty entitles you to standard warranty services for your HP5000 Model D640 printer
and is available from HP worldwide. However, there may be local variations in the level of
warranty service. You should contact the local HP Service Center to check for the applicable
local warranty in your country or province.
90 Day On-Site Limited Warranty
Hewlett-Packard warrants the HP5000 Model D640 printer and accessories against defects in
materials and workmanship for a period of 90 days from purchase by the end user. During the
warranty period, HP will, at its option, either repair or replace products which prove to be
defective. The warranty period begins on either the date of delivery, or, where the
purchase price includes installation by Hewlett-Packard, on the date of installation.
To have your HP5000 Model D640 printer serviced by HP, contact the closest HP Service
Center.
Exclusions
The warranty on your HP5000 Model D640 printer and accessories shall not apply to defects
resulting from:
•Improper or inadequate maintenance by customer.
•Customer supplied software or interfacing.
•Unauthorized modification or misuse.
•Operation outside of the environmental specifications for the product.
•Operation of non-supported printing media.
•Duty cycle abuse (see note below)
Warranty
Warranty and Support F-7
Warranty and
Support
•Operating the printer from a mechanical switch box without a designated surge protector.
•Improper site preparation and maintenance.
•Failure to perform key operator maintenance, as specified in the D640 User Manual.
•Use of non-HP consumables (see note below), memory boards, interface boards, or
adapters.
Note The use of non-HP consumable supplies alone does not affect either your warranty or
any maintenance contract you may have purchased. However, if an HP 5000 D640 printer
failure or damage is found to be to be attributable directly to the use of a non-HP consumable,
HP will not repair the printer free-of-charge. In this case, standard time and materials charges
will be applied to service your printer for that particular failure or damage
Operation of the printer beyond the limit of its duty cycle (printing greater than the equivalent
of 300,000 single-sided pages per month) shall be deemed printer abuse and all repairs thereaf-
ter will be billed on a time and materials basis.
If you are using a mechanical switchbox, ensure that it is equipped with a surge protector.
Damage to your printer could occur from the use of unprotected mechanical switch boxes.
Limitations
The warranty set forth above is exclusive and no other warrants, whether written or oral, is
expressed or implied. Hewlett-Packard specifically disclaims the implied warranties of
merchantability and fitness for a particular purpose.
Service During The Warranty Period
If your hardware should fail during the warranty period, contact an authorized HP dealer or
your local Customer Service Center.
Service After The Warranty Period
If your hardware should fail after the warranty period, contact an authorized HP dealer or your
local Customer Service Center. If you have an HP Maintenance Agreement, request service
under your agreement.
