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.

components (photoconductor drum, fuser, and paper pick roller) are replaceable without tools.
To further simplify operation and management, the D640 tracks toner, developer,
photoconductor drum, fuser, and paper pick roller usage and displays operator messages
advising replacement as needed.
Duplex Printing With No Performance Degradation
The D640 performs duplex printing (letter and A4 paper sizes) at 40 page sides per minute.
Accessories For the D640 Printer
About Your Printer 1-3

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.

just like an HP LaserJet IIIsi or 4si with an HCI, so jobs
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.

you may want to lock out this tray so that if the other two trays
ran out of paper, the letterhead would not automatically be
used. Locked trays are only selected if the print job contains
the command to select the locked tray.

Clip
OFF
=ON The D640 is able to print an image across the entire surface of the
physical paper. The image is clipped to prevent an image from
printing within 1/6th inch of any paper edge. This ensures optimum
print quality for the printed image.
If you don’t want this automatic clipping, you can set the printer to
Clip = OFF.
Even with Clip = OFF, the image will only print to the edge of the
paper if your print job contains the appropriate commands. See
“Setting Up Edge-to-Edge Printing” on page 6-23 for more
information.
Jamrecovery

OFF When a paper jam occurs, the printer reprints all pages that did not
completely exit the printer’s paper path. If you do not want pages to
automatically reprint after a paper jam is cleared, set Jamrecovery =
OFF.

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).

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.

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.

Ordering and Replacing Consumables 4-3
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
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.
Note Replace the cleaning roller every other toner replacement.
Caution Only add toner when the printer displays a toner low or toner empty message.
Never try to add toner before the printer requires it. Never add more than one bottle of toner.
Overfilling causes toner spills.
When the toner starts to get low, the Control Panel displays:

Introduction
Cleaning the D640 is an important factor in assuring optimum print quality. There are two
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.
Weekly Cleaning
5-2 Maintenance
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.
Toner Hopper Area
To clean the toner hopper area, follow these steps:
1. Turn off the main power switch, and open the upper right cover.
2. Use the toner vacuum to remove any toner on the upper surface of the toner hopper. Use
the supplied cleaning cloths to wipe up any toner or dust off the outside of the toner
hopper area. Clean all the way across the toner hopper area, paying careful attention to
the area in and around the toner hopper. Figure 5-1 illustrates the cleaning procedure.

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
Developer” on page 4-9.)

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.
