Using the Touch Control Panel
The front panel is located on the front right of the printer. It gives you complete control of your printer:
from the front panel, you can print, view information about the printer, change printer settings, perform
calibrations and tests, and so on. The front panel also displays alerts (warning and error messages)
when needed.
1. A Hi-Speed USB host port, intended for connecting a USB flash drive, which can provide files to
be printed. When a USB flash drive is inserted, a USB icon is displayed on the front panel's
home screen.
2. The front panel itself: a touch-sensitive screen with a graphical user interface.
3. The Power key, with which you can turn the printer on or off. The key is illuminated when the printer
is on. It flashes when the printer is in transition between on and off.

Is the product calibrated correctly after replacing a component? For information on the Service
Calibrations and how to use them see Service Menu on page 117.
ENWW Product Troubleshooting trees (MFP) 9
NOTE: Remember that certain Calibrations are required even if an Assembly has been disassembled
to gain access to another Assembly or Component.
Solving scan/print-quality problems
Refer to the Image Quality Troubleshooting Guide (in the EWS-Support Tab or in the CD).
The Touch Control Panel is blank
See What to do if the Touch Control Panel is blank on page 36.
The product does not power on
See What to do if the Touch Control Panel is blank on page 36.
The product continuously rejects printheads
▲Clean the flex contacts on the Printhead and in the Carriage Assembly using the Carriage
Interconnect Wiper and try again.
Cover sensors are not working
1. Perform the Sensors Test. See Sensors Test on page 96.
2. Check that the cable for the faulty sensor is not damaged and is connected correctly.
3. Replace the faulty Sensor.
The line sensor has problems detecting paper
1. Check the type of paper that is being used since the Line sensor may have problems detecting
transparent paper or some types of Non-HP paper. Try loading white HP paper in to the product
and check that the Line sensor detects it.
2. The Line Sensor is not calibrated correctly. Perform the Line Sensor Calibration. See Line Sensor
Calibration on page 164.
3. The Line Sensor is damaged or faulty. Replace the Line Sensor. See Line Sensor on page 325.
Troubleshooting Printer paper jams and printhead crashes
The failure modes "paper jam" and "head crash" are grouped together because in many cases a paper
jam causes the paper to lift up into the Carriage path and cause a Printhead crash, thus causing many
paper jam failures to be reported as head crashes.
1. Did the paper jam occur when loading paper?
●If the client has had paper jams, it is common for pieces of paper to get stuck in the paper
path. Clear the paper path.
NOTE: When clearing a paper jam, sometimes paper is stuck in the paper path. To clear this,
you must lift the Media Lever and insert thicker paper into the paper path to push out the paper
that is still stuck there.
2. Is the customer using non-HP paper?
●The use of non-HP paper can easily be the cause of paper jams and head crashes (especially
head crashes because HP paper is specially formulated to avoid cockle, one of the primary
causes of head crashes). If the paper is not HP approved, advise the customer to use HP
paper and check to see whether the problem is now solved.
10 Chapter 1 Troubleshooting ENWW
Troubleshooting Scanner paper jams (MFP only)
1. If while feeding paper into the Scanner a jam occurs, use the eject button on the Touch Control
Panel to clear the jam.
2. Unlatch the CIS Cover.
3. Open the CIS and clear the area of any paper.
The basket was damaged during the product setup
1. There are three plastic parts that could break during product installation and need replacing.
2. Check the parts table and graphics in Parts and Diagrams to identify what service parts you must
order. See Product Support on page 174.
3. Replace the component. See Bin Assembly on page 207.

Paper-handling troubleshooting
Roll paper The Touch Control Panel of the product indicates that paper is misaligned or incorrectly positioned
●The roll may be loaded the wrong way. The paper should load over the roll toward you.
●Check that the paper is correctly loaded onto the spindle.
●The paper may be loaded at an angle. The right-hand edge must be aligned with the blue line on the
Print Platen.
●Check that the Right Roll Support is properly attached and screwed to the product.
●The Rewinder, located on the Right Roll Support, should maintain proper back tension. If the Right Roll
Support is misaligned or not properly attached to the product, the Rewinder will not function properly.
●To further diagnose problems with the Rewinder, see Rewinder Test on page 98.
●If the customer is experiencing problems with paper jams, check that the Overdrive is not obstructed
by paper or that the Turn Drive Roller Service Utility is being used. See Turn Drive Roller
on page 120
●While attempting to load roll media, if the Front Panel prompts you to remove paper, although no paper
is loaded, calibrate the sheet sensor, refer to Calibrate Sheet Sensor on page 169
Sheet paper ●The sheet must be loaded with the right-hand edge against the white line on the upper roll cover.
●The paper may be crumpled or warped or may have irregular edges.
●If the printer incorrectly detects the presence of a sheet of paper, perform the Calibrate Sheet Sensor,
refer to Calibrate Sheet Sensor on page 169.
●If hand-cut paper is used, the edges may not form a right-angle or they may be rough. If possible, hand-
cut paper should not be used. Only purchased sheet paper should be used in the product.
●If you have problems with paper jams, check that the Overdrive is not obstructed by bits of paper or
using the Turn Drive Roller Service Utility. See Turn Drive Roller on page 120.
●When attempting to load sheet paper from Front Panel, if the printer displays a media skew message
repeatedly, and sheet cannot be loaded, calibrate sheet sensor. refer to Calibrate Sheet Sensor
on page 169

Introduction to ink supplies
Introduction to ink supplies
What are ink supplies?
For each of the ink colors used in the product, there are two components, the Printhead and Ink
Cartridge. These components are called Ink Supplies.
Ink cartridges
The product's six Ink Cartridges provide matte black, magenta, yeloow, cyan, gray and photo black ink
to the Printheads. The color Ink Cartridges supplied with the product have a capacity of 69ml but optional
130 ml are also available.
All these Ink cartridges are physically the same size. Only the internal capacity varies.
ENWW Ink-supplies troubleshooting 13
The Ink Cartridges for the T product series require no maintenance or cleaning. As long as each Ink
Cartridge is inserted correctly into its slot, the ink will flow to the Printheads. Because the Printheads
control the amount of ink transferred to the page, you will continue to see high-quality printing results
even when the ink levels are getting low.
The Touch Control Panel displays the status of the Ink Cartridge. Using the Touch Control Panel,
detailed information can be checked on the Ink Cartridges.

HP 726 300 ml Matte Black Ink Cartridge (T1300 series only) CH575A
Printheads
The Printheads are extremely durable and do not need to be replaced every time an Ink Cartridge is
replaced. They are independent of the Ink Cartridges and will continue giving excellent image-quality
results even if the Ink Cartridges are low on ink.

●Do not touch the end of the Ink Cartridge which is inserted into the product as there may be a small
amount of ink on the connection.
●Avoid storing partially used Ink Cartridges on their ends.
When should you replace the ink supplies?
When to change the ink supplies is mostly determined by you with guidance from the Touch Control
Panel. In conjunction with the messages displayed in the Touch Control Panel and the message
explanations in this chapter, you will be able to choose for yourself when is the right time to change the
ink supplies.
The product will also display the ink level and will tell you when the ink supply is low on ink. This means
you have constantly updated information about the ink supplies.
Ink cartridge levels, information and replacement
Ink cartridge levels and information
The Touch Control Panel displays Ink Levels shown as level bars. These bars represent how much ink
is remaining in the Ink Cartridges: as ink is used up the bars get shorter in length. To view the ink levels
perform the following steps:
1. Press on the Information icon .
2. Press on the Ink Menu icon. Each of the Ink Cartridges is displayed as a bar indicating the level of
ink remaining.
3. To get further information of an Ink Cartridge, press on the corresponding bar that you want to view.
The information supplied is:
●The current status of the Ink Cartridge.
●The current ink level of the ink cartridge in milliliters.
16 Chapter 1 Troubleshooting ENWW
●Original capacity of the ink cartridge in milliliters.
●The make of the Ink Cartridge (HP no.72 is recommended).
●The product name of the Ink Cartridge.
●The product number of the Ink Cartridge.
●The serial number of the Ink Cartridge.
●The Expiration Date of the ink cartridge.
●The current warranty status of the Ink Cartridge.
●The manufacturer of the Ink Cartridge (HP is recommended).
The product consumes more gray ink than M, C, or Y
This is not a problem, and no action should be taken to “correct” this attribute of the product.
In general the higher frequency of change is because Matte Black ink is the one that is used for lines
and black objects in technical papers (bond, coated, HW coated, natural tracing paper, etc.), which are
the types of contents that are more commonly printed with this type of product.
About gray ink
The T Series products are the first HP Designjet technical products to include Gray ink. One thing that
users may notice is that Gray ink is used in higher quantities than Cyan, Magenta and Yellow inks. This
happens because of the following reasons:
1. Gray areas (which are very typical in technical drawings) can now be printed by using only Gray
ink. In the past, these areas had to be printed by combining Cyan, Magenta and Yellow inks. This
means that Gray ink is used more frequently than the rest of the inks (C, M, Y) which are now used
less frequently, so the difference in consumption is noticeable. However overall the T Series
products will actually need to use in total less ink to print gray areas than previous Designjet
products.
2. Soft colors can now be printed by combining C, M and Y inks with Gray. The addition of Gray ink
softens the color, improving transition areas. It also allows printing soft colors by using less C, M
and Y. These two types of contents are very typical and make the consumption of Gray to increase
and the consumption of C, M and Y to decrease.
Conclusion
However, no matter the combination of inks that are used, when the total cc’s of ink are added up, the
T Series products will always have a lower ink consumption than the HP Designjet 500, 800 and 1000
series for equivalent contents with equivalent levels of print quality.
Changing an Ink Cartridge
There are two occasions when you need to remove an ink cartridge:
●The ink cartridge is very low and you want to replace it with a full cartridge for unattended printing
(you can use up the remaining ink in the first cartridge at a more convenient time).
●The ink cartridge is empty or faulty, and you must replace it to continue printing.
NOTE: Do not try to remove an ink cartridge while printing. Remove an ink cartridge only if you are
ready to insert another one.
Make sure the product wheels are locked (the brake lever is pressed down) to prevent the product from
moving.

Aligning Printheads
Precise alignment between printheads is essential for accurate colors, smooth color transitions, and
sharp edges in graphical elements. Your product has an automatic printhead alignment process which
runs whenever a printhead has been accessed or replaced.
In cases where the paper has jammed, you have used a custom paper, or are experiencing problems
with color accuracy you may need to align the printheads. If the paper has jammed, it is recommended
that you reinsert the printheads and initiate the realignment procedure with the Image Quality
Maintenance menu.
NOTE: Do not use transparent and semi-transparent paper to align the printheads. Photo paper is
recommended for the best quality.
Reinsert Printheads Procedure
1. If the realignment process is running and the wrong paper is loaded, press the Cancel button on
the Touch Control Panel. Do not print if the realignment process has been canceled. You can restart
the alignment with the Image Quality Maintenance menu procedure.
2. Load the paper you wish to use. You can use a roll that is at least 610 mm (24 in) wide or a cut
sheet that is A2 landscape or larger.
3. Remove and re-insert all the printheads, see Remove a printhead and Insert a printhead. This will
start the printhead alignment procedure.
4. The process will take about six minutes. Wait until the Touch Control Panel display shows the
process complete before using the product.

Image Quality Maintenance Procedure
1. Load the paper you wish to use. You can use a roll that is at least 610 mm (24 in) wide or a cut
sheet that is A2 landscape or larger. Do not use transparent and semi-transparent paper to align
the printheads. Photo paper is recommended for the best results; plain, bond and thin coated
papers provide acceptable but marginal results.
2. Press the Menu button to access the main menu and select the Image Quality Maintenance menu
icon.
3. Select Align printheads. The product will check to see if it has enough paper to run the realignment.
4. The realignment procedure will now be performed and the realignment pattern will be printed.
5. The process will take about five minutes. Wait until the Touch Control Panel display shows the
process complete before using the product.
Scanning errors during alignment
If the alignment process FAILs, a Scanning error message is displayed on the Touch Control Panel.
This means that the alignment has not completed successfully. The problem may be due to:
●The paper used was not valid, repeat the alignment with valid paper.
●Printhead health problems, clean printheads.
●The alignment was done with the Scanner open, repeat the alignment with the cover closed.
If the problem persists after using valid paper, cleaning the printheads, and keeping the cover closed,
there may be a failure in the scanning system needing reparation or the printheads, although clean, may
not work and need to be replaced.

4. Clean the electrical connections on the backside of the printhead with a lint-free cloth. You can
carefully use a mild rubbing alcohol if moisture is needed to remove residue. Do not use water.
You can use the Flex Contacts Cleaning Tool.
This is a delicate process and may damage the printhead. Do not touch the nozzles on the bottom
side of the printhead, especially not with any alcohol.
5. Reinsert the printhead.
6. Check the Touch Control Panel display message. If the problem remains, try a new printhead.
Maintaining and cleaning the printheads
Clean the printheads
As long as the product is kept turned on, an automatic cleaning is performed periodically. This ensures
there is fresh ink in the nozzles and prevents nozzle clogs, which ensures color accuracy.
For image quality issues, you can also refer to the Maintenance and Troubleshooting document.
To clean the printheads, press the Menu key to return to the main menu and select the Image Quality
Maintenance menu icon, then Clean printheads. If you have gone through the Image Quality Diagnostic
print process, you know which colors are failing. Select to the pair of printheads which contain the failing
colors. If you are not sure which colors to clean, you can also select to clean all printheads.
Cleaning all printheads takes about nine minutes. Cleaning a single pair of printheads takes about six
minutes. Cleaning all printheads uses more ink than cleaning a single pair.
If you have cleaned the printheads using the Clean printheads procedure from the Touch Control Panel
and are still experiencing image quality problems, you can try cleaning the printhead nozzles manually
using the following procedure.
NOTE: This is a delicate process and may damage the printhead. Do not touch the electrical
connections on the backside of the printhead.
You must remove the printhead (see Changing a Printhead on page 20) and using a cotton swab and
a little de-ionized, distilled water, or Carriage Interconnect Wiper clean the bottom of the printhead until
the residue is removed.
Flex Contacts Cleaning Tool
NOTE: The Flex Contacts Cleaning Tool is part of the Maintenance Tool Kit. All the instructions needed
to use the Flex Contacts Cleaning Tool will be packaged with the kit.
ENWW Ink-supplies troubleshooting 29
Whenever you replace the Printhead, check the empty slots to see if they need cleaning. In extreme
circumstances, when a Printhead is inserted, it is possible that the product will not recognize it due to
the build-up of ink on the electrical connection between the Printhead and the Carriage Assembly.
Included with the product is a Flex Contacts Cleaning Tool. This tool is provided in a separate package.
It also contains replacement sponges and an instruction sheet. This tool should be used for cleaning
the electrical interconnects of both the Carriage Assembly and the Printhead.
If the Touch Control Panel displays the message “Reseat” or “Replace” next to the offending printhead,
try cleaning the flex circuits of the Carriage and the Printheads using the Carriage Interconnect Wiper.
NOTE: Do not touch, wipe or attempt to clean the printhead nozzles. This can damage the printhead
and reduce print quality.

If you have an error code that you cannot resolve, then report the error to the HP Response Center or
the nearest HP Support Office. When reporting the error, have the following information ready:
NOTE: If you fail to provide any of the following information, HP Support cannot help you properly.
Make sure you take time to gather all of this information.
●Model and Serial Number of the product, this can be found in the Diagnostics menu, scroll to Unit
Information.
●Which firmware revision the unit is using. this can be found in the Diagnostics menu, scroll to Unit
Information.
●The complete error number, this information can be found in the Product/Printer Information Area.
●The Service Configuration Print. To print this press , then go to 'Internal Prints>Service
Information Prints'.
ENWW Introduction 35

Information Prints'.
●Which software application the customer is using.
●The internal error code, file, and line fields found on the Internal Error Screens available by
pressing Up and Cancel at the same time when the System Error is shown on the Touch Control
Panel. To get the file and line fields, you need to scroll down to the next screen.
NOTE: The file and line fields are important to identify the source of the problem because the
same internal Error Code can be reported in different files and line. In the File field, supply only the
last part of the value (from last slash “/” to the end of the line). For example: for a file: /ae/…./elektra/
hal/motors/ControlledMotor/Elektra/ControlledMotorElektra.cpp you’ll only need to provide the
“ControlledMotorElektra.cpp” part to HP support.
TIP: When investigating a system error, you are recommended to use the diagnostic package to further
understand the problem. To obtain the diagnostic package (which takes a few minutes), see Appendix
C: Obtaining the product log and the diagnostics package on page 74.
Product logs
It is possible to view all the activities the printer performs collected in a log file. To further understand a
system error code, it is useful to have a log showing what the printer was doing at the time when the
system error occurred.
To get product logs, see Appendix C: Obtaining the product log and the diagnostics package
on page 74.

Problem Description: Out of memory
Corrective action: Restart the product.
Warning: 71:04
56 Chapter 2 System Error Codes ENWW
Problem Description: Out of memory.
The total memory available in the product depends on its configuration. It is reported as HP-
GL/2 memory or PS/PDF memory. If the amount of memory that the product needs to process
the file is more than the amount available, the product will display this system warning. The
amount of memory required for processing the file is known as the ‘display list memory’:
●The display list memory should not be confused with the file size of the print job. The size
of the display list memory depends on several variables such as the resolution, file size
and file content.
●The display list memory is not visible to the user, but can be consulted by engineers to
troubleshoot out-of-memory issues. See Appendix D: How to check the display list
memory for an HP-GL/2 job on page 77
.
●There have been a few cases in which a print job with a relatively small file size has
triggered an out-of-memory message. Such print jobs typically have a large number of
objects in them or have complex objects such as raster images with gradients or objects
with multiple layers.
Corrective action: Try the following:
1. Upgrade the firmware to the latest version available.
2. Decrease the print resolution to 300 dpi.
NOTE: If the customer does not accept the print quality after reducing the resolution or
using Econofast print mode, proceed to the workaround in step 3.
ENWW System Error Codes—Full Descriptions 57
◦The resolution required by the product to process the file is set by the print mode
selected (Best, Normal, Fast). There is a setting available that enables you to
decrease the resolution for each print mode to 300 dpi. If this setting is used, the
rendering resolution will be reduced, but the output (printing) resolution will remain
the default of the selected print mode. There could be an impact on Image Quality
because of the reduction in the rendering resolution; this will be especially noticeable
in circles and lines with very low inclination.
3. Use the ‘Econofast’ print mode. The rendering resolution will be set by default to 300 dpi.
In the Paper/Quality tab of the product properties window, select Custom options and
press the Settings button. In the Custom Print Quality Options window, check the
Economode box.
NOTE: If the Out of Memory message still persists, proceed to the next workaround.
4. Out of Memory issues can always be solved if the processing of the job can be performed
before reaching the product. This can be done by selecting ‘Send Job as Bitmap’. The
main processing of the print job will then be performed by the computer. This form of
printing is recommended when the print job contains raster images, and mixed plots with
raster images and lines, because the process of turning a print job made of raster images
to vector images leads to a significant increase in the display list memory.

Appendix A: How to troubleshoot SE 79:04
Introduction
The system error 79:04 is a generic firmware error (equivalent to a blue screen in windows). It’s the
system error that the product will display when an unknown exception occurs that cannot be identified
as relating to any specific subsystem of the product.
Since this is a generic error, there can be multiple causes behind it. This document will cover the most
probable causes behind a system error 79:04 and will recommend the most efficient troubleshooting
steps to resolve customer issues.
It is important to mention that, although 79:04 system errors can be caused by a hardware malfunction,
the vast majority of 79:04 system errors are pure software or firmware issues. Before doing anything
else, you are recommended to try the following general-purpose solutions.
1. Update the product’s firmware to the very latest available firmware version, even if the product
appears to be running the latest firmware already.
2. Restore the factory settings from the Touch Screen Panel's Setup menu.
If these do not solve the problem, continue reading about other possible solutions below.
Possible causes
Since the 79:04 system error is a generic error, the number of possible causes behind it is large. The
majority can be grouped, however, into the following groups.
Job related SE79:04
A specific print job that is not correctly formatted for the product or that is not correctly processed by it
can trigger a 79:04 system error.
The incorrect format or processing can come from two sources:
●Incorrect commands in the job itself. For example, a PS job with some commands that do not have
the correct PS format.
●Issues applying to the settings in the job
Possible symptoms
64 Chapter 2 System Error Codes ENWW
79:04 caused by a print job always have the same symptoms:
1. The job is received by the product and starts to process.
2. In the middle of the processing, the product stops and displays 79:04.
3. The product will display the 79:04 system error again after reboot. This is due to the fact that the
product will try to reprint the job, which is pending in the queue, after reboot.
4. After the second reboot, the product will start up normally
5. If the same job is sent again, it will always produce a 79:04 system error
These types of 79:04 system errors are normally caused by jobs that have been generated by 3rd
party applications (RIPs, 3rd party drivers, files exported by an application to PS, PDF, HP-GL/2,
RTL, … or any other format supported by the product). Jobs generated by HP drivers will not
normally generate 79:04 system errors, since the output that our drivers generate is very controlled
and has been designed taking into consideration the characteristics of our product’s language
interpreters.
There is an exception to this general rule: there are certain applications that can generate their
own PS code (Adobe PhotoShop, Adobe Illustrator, Adobe Acrobat, Corel Draw, Freehand,
QuarkXpress, …). When used with a PS driver, these applications generate the output PS
themselves, instead of using the driver’s rendering capabilities. This is known as PostScript pass-
through. So, when using an HP PostScript driver together with an application that has PS
passthrough capabilities, the PS code that comes into the product has not been rendered by the
HP driver, and, should the source file contain any PS commands that are not correctly processed
by the product, a 79:04 system error could occur even though an HP driver is being used.
Solutions and workarounds
When a job consistently generates a 79:04 system error, it is either because of a issue in the
product’s firmware or because of a defect in the job itself (when it has been generated by 3rd party
SW). In order to identify the cause and find out a solution, these issues should always be
impapertely escalated to the GBU through the GCC.
Also, there are some workarounds and short-term solutions that can be tested in order to get the
customer up and running in the shortest possible time:
1. Send the job using a variety of different settings. Many times, the issue is caused by a combination
of the job contents combined with some specific setting(s).
2. If the customer is sending the file directly to the product, try using the HP driver instead.
3. If the issue is occurring when printing through the HP PostScript driver from an application with PS
passthrough, try changing the options in the application so that it prints PS as raster (the option is
typically located in the “Advanced” options of the application’s printing dialog).
4. In some cases, there may be an unfortunate interaction between the particular job and the I/O
connection used to send that job to the product. Try sending the same job using a print queue that
uses a different type of connection. For example, use a network connection instead of USB, or use
the LPD network printing protocol instead of port 9100.
Data related SE79:04
HP Designjet products have Hard Disks and non-volatile memories that contain databases and files that
can be modified with user data. Some examples include:
●The product’s queue
●The hard drive partitions that contain user jobs
ENWW Appendix A: How to troubleshoot SE 79:04 65
●The database that stores the product settings
●The database that stores accounting information
Some of this data is accessed by the product at start-up, and some others are accessed as needed.
If any of this fields contains corrupt data or data with characters or values that cannot be correctly
processed by the product, a 79:04 system error may occur.
Possible symptoms
There are two different types of symptoms for data related 79:04 system errors:
1. When the corrupt data is accessed during start-up:
a. The product will display a 79:04 during the start up process
b. Switching the product off and on again will not solve the issue. The product will continue
displaying the 79:04 system error until the corrupt data has been cleared through a service
procedure
2. When the corrupt data is accessed during normal product operation:
a. The product will start up normally
b. When the data is accessed (for example while printing, while navigating the queue or when
changing some settings), the product displays a 79:04 system error
c. The product can reboot normally
d. When the data is accessed again (typically, under the same conditions as in step “b”), the
79:04 system error is displayed again
Solutions and workarounds
Many times, data-related 79:04 errors are resolved by means of hardware intervention. Since data are
stored in physical components (RAM, EEROM and Hard Disk), replacing these components with new
ones that are empty usually solves the problem. However, there are quicker and more effective solutions
to these types of errors:
1. Clear all information that has been introduced by the user using the standard tools available in the
product.
a. Delete all jobs from the queue (from the Touch Control Panel or the EWS).
b. Reset to factory defaults to clear the user’s configurations and calibrations.
c. Delete any non-standard paper preset in the product (both the ones that have been created
by the user and the ones that have been installed as OMES profiles through the EWS or the
HP product Utility).
2. If step 1 did not resolve the issue, you can use Service Tools to clear additional information that
could be causing the issue.
a. Start the product in Diagnostics Boot Mode.
b. Perform an EEROM reset.
66 Chapter 2 System Error Codes ENWW
3. If step 2 did not resolve the issue, it is possible to run a recovery of the hard disk.
a. Start the product in Diagnostics Boot Mode.
b. Perform a Hard Disk Recovery. This will erase data from the hard disk and reinstall the current
firmware. It may take up to half an hour.
4. If step 3 did not resolve the issue, you can check the hard disk's file system.
a. Start the product in Diagnostics Boot Mode.
b. Perform a File System Check. This will fix any error in the file system structure. It may take a
few minutes, or up to an hour, depending on the state of the hard disk.
Important note:
It is possible that the corrupt data came to be in the product as a consequence of some activity in the
customer’s workflow. In this case, it is possible that the issue will happen again. In these cases, it is
very important to understand the sequence of events in the customer’s workflow that led to the error
occurring. Once the error can be traced in the customer’s workflow, escalate the issue to the GBU
(through the GCC). This is done to implement any changes in the product’s firmware that can prevent
these issues occurring again.
Network related SE79:04
Most HP Designjet products have built-in networking capabilities. Network settings can be set manually,
but in the majority of cases, they are obtained automatically from the product. These settings include
many different fields, such as IP address and subnet mask, available gateways, host and domain names,
etc.
In some cases, there can be issues in the firmware that can cause a certain value in one of these fields
to be interpreted incorrectly, and this can lead to a 79:04 system error.
Symptoms
There is no single set of symptoms that can absolutely pinpoint a network related 79:04 system error.
However, the following guidelines can be applied:
●It can happen when the product starts up or when accessing the Network Configuration section of
the Touch Control Panel or Embedded Web Server. It can also occur apparently randomly when
the product is connected to the network. It can also occur any time a particular network action is
performed, for example when print jobs are sent to the product, or when connecting to the
Embedded Web Server.
●In all these cases, repeating the action after restarting the product with the LAN cable disconnected
does not cause the 79:04 error to occur.
Solutions and workarounds
In the majority of cases, these issues are due to an issue in the product’s firmware. As soon as the
conditions in which the issue happens are understood, it should be escalated to the GBU through the
GCC.
At the same time, the following short-term solutions and workarounds can help the customer to get up
and running in the shortest possible time:
1. Disconnect the network cable in order to restart the product and change network settings.
2. Try resetting the embedded networking settings or Jetdirect settings. See Connectivity
troubleshooting on page 31.
3. In the Network configuration menu in the Touch Control Panel, disable any protocols that you are
not using, including IPv6, IPSec, SNMP and WebServices.
ENWW Appendix A: How to troubleshoot SE 79:04 67
NOTE: Disabling SNMP or WebServices means that customers may not be able to see product
status information; and s and Mac OS print-queue installers will require the user to specify the
product’s IP address and product model manually.
4. If the above steps do not work, try using a different type of print queue. For example, if the problems
occur when printing to a Port 9100 Socket print queue, try using the LDP protocol instead, or USB.
To do this, create a new print queue of the type required and try printing using the new queue
instead.
5. If the above steps do not work and the customer is using the product’s embedded LAN connection,
try using an accessory Jetdirect card instead. Similarly, if the customer is having problems using
an EIO Jetdirect card, try disconnecting the Jetdirect card and using the embedded networking.
In most cases, network problems that seem to occur randomly (when the product is not being sent print
jobs) are caused by an interaction between some other devices in the customer’s network and the
product. Isolating the product from other devices in the network as much as possible by connecting the
product to a private network or a different network subnet may help the customer continue working until
the root cause of the problem is understood and solved.
User Interaction related SE79:04
In some cases the product may not react as expected when a certain set of conditions coincide. In these
cases, if the product doesn’t know how to react, it may simple display a 79:04 system error and force a
reboot. Some examples (not real) that can help to illustrate this:
●An error occurs when a job is cancelled when it is at the “Finishing print” state and when the queue
is disabled
●An error occurs if the Scanner is opened while the product is checking the printheads
These errors will most likely only happen in very specific corner cases that have not been identified
during the development or the qualification of the product, so normally, they do not severely impact the
customer, as they do not affect their regular working flows.
Symptoms
The symptoms here are as numerous as the number of possible interactions between the user and the
product. In any case, it’s possible to identify the steps that caused the error to occur and avoid them as
the steps will always be the same with no variance.
Important: An major element in determining the error is what the state the product was in at the time the
error was displayed. Actions the user has made when the product is drying for example can produce
an error, whereas the same action when the product is doing something else (or is idle) may not produce
any errors.
Solutions and workarounds
The recommended action plan in these cases is to identify the previous steps that caused the error and:
1. Escalate the issue to the GBU through the GCC in order to have it corrected in the firmware.
2. Recommend to the customer that they try to avoid the same steps to prevent the issue
3. If the conditions that cause the error are in the customer’s regular workflow, try to identify a different
way of achieving the same result out of the product.
Random SE79:04: Concurrence issues and memory leaks
Some 79:04 errors happen randomly when the product is being heavily used. However, it’s impossible
to find a single set of conditions that reproduce the problem. It just happens from time to time, without
a defined pattern.
68 Chapter 2 System Error Codes ENWW
These random 79:04 can have two different types of root causes:
●Memory leaks: before a program is executed, it allocates the memory it will need. After the
execution is complete, the allocated memory is freed to be used by other programs. If the allocation
or the release of the memory are not properly programmed, every time the program is executed
some memory will be incorrectly labeled (either as used or as free). This is known as a memory
leak. When a program with a memory leak is executed a lot, the memory becomes progressively
full (since it is not properly freed). When the leak becomes too big, the product is left ‘out of memory’
to execute new processes and a 79:04 is triggered
●Concurrence issues: there are certain resources that can be accessed by multiple programs or by
multiple executions of the same program (what is known as multiple threads). Access to these
resources must be correctly controlled to prevent unexpected behavior. Issues caused by an
incorrect control of these resources are concurrence issues.
In the following you have a simple example: let’s imagine that there is a counter that controls the
communication between the Jetdirect card and the product’s firmware. Whenever a new packet of
information is sent by the Jetdirect card to the product, the counter increases. When the product receives
the packet and processes it correctly, the counter decreases. Another process checks the counter from
time to time to see its value and take conclusions from it. If the counter is near 0, it means that the
product is processing correctly, and if it grows too big, it may mean that there is a bottleneck somewhere
and maybe the Jetdirect card throughput is decreased to control its speed to the product. However, if
the access to this counter is not properly controlled, undesirable effects may happen: in a real
environment, a Jetdirect card processes thousands of information packets per second, so this counter
is updated frequently, both by the Jetdirect and the product. If at a certain point the Jetdirect and the
product try to access the counter at the same time and the code is not prepare to handle this, it may
happen that the Jetdirect cannot increase the counter because the product is writing to it, and what’s
worse, that it does not realize this fact. If this happens a few times each second, it may happen that the
counter is decreasing faster than it’s increasing and that at a certain point it has a negative value. And
then, what will the process that is checking this counter do? Most likely, the process will not be prepared
to react to a negative value and will launch an exception that will trigger a 79:04 system error.
Symptoms
This type of 79:04 always occurs in heavy load conditions, so the symptoms will always be similar to
this pattern:
●A product that is being heavily used (printing a project or in a reprographics environment) produces
79:04 errors randomly, forcing the user to reboot.
●After rebooting, the product can be used without any issues for an extended period of time, but if
the workload is consistently high, a random error will occur again.
●The error can never be associated with a specific file. The file that was being printed when the error
occurred the last time can be printed without issues after reboot. And a file that has been printed
without issues several times can trigger the error in the future.
●This error is very dependant of the workflow the customer has. The most common user workflows
have been extensively tested both by HP and by our beta sites, so it is highly unlikely to see random
79:04 issues in these cases. These random issues tend to occur in very specific corner cases, and
cannot be reproduced unless the exact conditions of the workflow are replicated. They normally
happen when sending files generated by external applications (RIPs, 3rd party drivers, etc.)
Workarounds and solutions
ENWW Appendix A: How to troubleshoot SE 79:04 69
Random 79:04 errors are, by far, the most complex ones to diagnose and to fix. The only solutions
available in these cases are:
1. Run the Hard Disk Recovery utility (see Hard Disk Recovery Utility on page 132).
2. Identify the root cause (either in the files or in the firmware) and fix it in the code, which requires
the intervention of the GBU.
3. Test any options available to modify the customer’s workflow and see if any combination of them
solves the issue.
In both cases, a profound understanding of the customer’s workflow is necessary. In particular, the
information that is needed is:
●Product Touch Control Panel settings
●Application that is being used; RIP or driver that is being used
●Application/RIP/Driver settings
●Type of output files this application, RIP or driver is generating
●Some sample files that are representative of what the customer is using
●Operating System
●Method of connection to the product
●A description of the normal flow when the issue occurs and the typical frequency of occurrence (for
instance, once every hour when sending several files non-stop, each of them with multiple copies)
You are recommended to use the Diagnostics Package to obtain this kind of information.
With this information, the environment can be replicated in order to try to find workarounds. This is also
the information that will be needed at the GBU to investigate and fix the root cause of this issue once it
is escalated.
Hardware related SE79:04
Hardware is, by far, the least likely cause of a 79:04 system error. Replacing hardware components
does not normally fix the issue and increases the total turn around time in finding a workable solution.
In some cases, a failure in a component in the product’s electronics may cause a 79:04 system error,
since the product’s electronics are involved in the execution of the firmware and the processing of jobs.
It needs to be noted, however, that hardware failures in the electronics tend to produce specific system
errors that point directly to the component that is failing.
Some hardware problems that could cause the 79:04 error are:
●Defective clusters in the Hard Disk drive. If these clusters are used to execute the firmware or to
process a job, they may produce a 79:04. It needs to be noted however, that most 79:04 errors
that are resolved by an HDD replacement are in fact, data related 79:04 that could have been
solved more efficiently and quickly following the other steps.
●Defective memory segments. If the RAM memory has some defective segments, a 79:04 may occur
when these segments are used.
●Intermittent defects in the electronic components that are involved in the processing of a job:
Carriage PCA, Trailing cable, Formatter and Engine PCA. This is a highly unlikely cause, since
defects in these components will produce subsystem specific errors.
Symptoms
70 Chapter 2 System Error Codes ENWW
There’s no single set of symptoms behind hardware related 79:04 system errors. The most usual ones,
however are:
●79:04 during start up. Rebooting the product may or may not solve the problem
●79:04 while processing or printing a job. Rebooting the product and printing the same job does not
always produce the error.
Solutions and workarounds
In the following procedure perform each step as it appears in the list and only move on to the next step
once you are sure the 79:04 error has not been cleared:
1. Reboot the product in Diagnostics Boot mode and execute the service tests to validate the
functionality of all the electronics components
●Perform the troubleshooting for “data related 79:04” system errors, refer to Appendix A: How
to troubleshoot SE 79:04 on page 64
2. Replace the memory
3. Replace the HDD Hard Disk Drive on page 295
4. Escalate the issue before replacing any additional parts.
Troubleshooting based on symptoms
This section will describe which troubleshooting steps to perform for a 79:04 system error based on the
symptoms of the issue. Perform each step as it appears in the list and only move on to the next step
once you are sure the 79:04 error has not been cleared:
Touch Control Panel displays 79:04 at Start-up
1. Reboot the product twice. If the System error has been caused by a job because its in an incorrect
format, rebooting twice will clear the error (the first time after reboot, the product will attempt to
print the job again, and this will cause the error to reoccur). If rebooting the product twice solves
the issue, then it is an issue related to the job and you should refer to the section on a Job Related
SE79:04.
2. Upgrade the product’s firmware. Even if the currently installed firmware version is the latest one,
re-install it. Since the product cannot start normally, you will need to upgrade the firmware while
booting the product in Diagnostics Boot Mode. For this, a special file and a special upgrade process
will be needed. For more information, see Appendix B: Emergency firmware upgrade with USB
flash drive on page 74 .
3. Disconnect the network cable and restart the product. If this solves the problem, then it is a network
related 79:04 and you should follow the guidelines for this type of 79:04.
4. Remove all cartridges, printheads and printhead cleaners (if available). Unload the paper. Restart
the product. If the product can start normally, insert the consumables one by one until you isolate
the one that is causing the error. Do not insert any of the replaced consumables in another product
5. Restart the product in Diagnostics Boot Mode and perform the “Electronics test”. If an electronic
component is identified as faulty, replace it.
●Restart the product in Diagnostics Boot Mode and Reset the EEROM. If the issue is solved
by this, this is a data related 79:04 system error and you should follow the guidelines, refer
to Appendix A: How to troubleshoot SE 79:04 on page 64.
6. If the unit has been used for some time and suddenly has started to show this behavior, replace
the Hard Disk Drive.
ENWW Appendix A: How to troubleshoot SE 79:04 71
7. If the issue is new and the issue happens since the first boot, do not replace the HDD.
8. If none of the previous steps solved the issue, escalate the issue with specific information, refer
to Reporting a system error to HP support on page 35
●Unit information: S/N, P/N, accessories
●Conditions where the problem occurs and conditions prior to the first occurrence of the
problem
●The results of the previous 8 steps
●The System Error detailed information (this can be obtained by pressing CANCEL + Down)
●The product logs. In order to obtain the product logs, see Appendix C: Obtaining the product
log and the diagnostics package on page 74.
Touch Control Panel displays 79:04 during product operation – not while sending jobs
1. Reboot the product.
2. Upgrade the product’s firmware. Even if the currently installed firmware version is the latest one,
re-install it.
3. Reset the product to factory defaults, EEROM Reset Utility on page 113
4. In order to narrow the scope of the issue, try the following:
a. Disable the queue
b. Disable any unused network protocols
c. Disable SNMP and WebServices (if they are available in the product)
d. Disable “Sleep mode” from the Service Utilities menu
e. Delete any Paper Presets that you may have uploaded or created using the product's
Spectrophotometer
5. Restart the product in Diagnostics Boot Mode and perform the “Electronics test”. If an electronic
component is identified as faulty, replace it.
6. Format the Hard Disk drive. To do so, you will need to start the product normally, enter the Service
Utilities menu and then the Secure Disk Erase option. Set the Erase method to “Fast Erase” and
then perform the disk erase process, refer to Disk Wipe DoD 5220.220M on page 129. This will
take 45-75 minutes and will erase all user information from the disk, resolving any issue caused
by corrupt data. After the erase process, a firmware update will be required. If this solves the issue,
this is a data related 79:04 system error and you should follow the guidelines for this type of error.
7. Try to identify the combination of settings or actions that led to the system error and try to reach
the same result with a different combination. Escalate the issue to fix the original problem.
8. If none of the previous steps could solve the issue, escalate it with specific information, refer to
Reporting a system error to HP support on page 35.
Touch Control Panel displays 79:04 while printing
While printing a single job
72 Chapter 2 System Error Codes ENWW
The error happens after a single job is sent. It’s easy to identify which job has produced the error, since
every time that this same job is sent, the error is displayed.
1. Reboot the product twice (after the first reboot, the product will show the 79:04 system error again,
since the product will attempt to reprint the last job in the queue, which is the one that caused the
issue)
2. If you are using an HP driver, update the driver to the latest version
3. Upgrade the product’s firmware. Even if the currently installed firmware version is the latest one,
re-install it. Send the job using different print settings. The following ones can be helpful:
a. Try sending the job without selecting a paper profile in the driver
b. Try changing the Image Quality settings
c. If you are using the HP-GL/2 driver, try the option “Send job as bitmap”
d. If you are using the PS driver, try using the HP-GL/2 driver instead
e. If you are using the PS driver from an Adobe application (or any other application that can
handle PS), try changing the application’s print settings so that the PS is generated as Raster.
4. Try the following Touch Control Panel settings:
a. Change the Print Language option in the Touch Control Panel from “Automatic” (which is the
default setting) to the language that is being printed (PS, HP-GL/2, …)
b. Queue = OFF
c. Start Printing = After processing
d. For PS SKUs, try changing the encoding setting (“Automatic” by default) to Binary or ASCII
5. If you are using a 3rd party application that does not print through the HP driver, try modifying the
printing workflow by:
a. Using an HP driver
b. Changing the settings in the application’s printing dialog
6. If you are using an accessory Jetdirect card, try using the internal network connector or USB (if
available).
7. Escalate the issue, providing specific information, refer to Reporting a system error to HP
support on page 35.
Random 79:04 during continuous printing
The error does not happen with a single job. It happens randomly during continuous printing, normally
while the product is managing a heavy load (printing a project or in a reprographics environment).
This type of error is caused either by memory leaks or by concurrence issues in the product’s firmware.
They normally happen in non common environments where these memory leaks or concurrence issues
that have not been detected during qualification have occurred. These issues cause the product to crash
at a completely random moment during printing, and are not associated to a specific job.
Because of this, troubleshooting these issues is normally quite complex.
1. Reboot the product twice (after the first reboot, the product will show the 79:04 system error again,
since the product will attempt to reprint the last job in the queue). If after the second reboot the
issue continues occurring randomly, continue troubleshooting.
2. If you are using an HP driver, update the driver to the latest version
ENWW Appendix A: How to troubleshoot SE 79:04 73
3. Upgrade the product’s firmware. Even if the currently installed firmware version is the latest one,
re-install it.
4. Try restoring the factory default settings from the product's Touch Control Panel.
5. Try the following changes in the workflow:
a. Change the Print Language option in the Touch Control Panel from “Automatic” (which is the
default setting) to the language that is being printed (PS, HP-GL/2, …)
b. Queue = OFF
c. Start Printing = After processing
d. For PS SKUs, try changing the encoding setting (“Automatic” by default) to Binary or ASCII
e. If you are using the HP-GL/2 driver, try sending the job as a bitmap
6. If you are using a 3rd party application that does not print through the HP driver, try modifying the
printing workflow by:
a. Using an HP driver
b. Changing the settings in the application’s printing dialog
7. Escalate the issue with specific information, refer to Reporting a system error to HP support
on page 35
Appendix B: Emergency firmware upgrade with USB flash
drive
When it is not possible to perform a firmware upgrade using the normal procedures (for instance, in
case of a System Error and the Embedded Web Server is unavailable), it is possible to perform an
emergency firmware upgrade using a USB flash drive. Follow the next steps:
1. Copy a valid FMW firmware file onto a USB flash drive. This file is provided in Designjet Online.
Remove all other contents in the flash drive.
2. Turn off the product.
3. Connect the USB flash drive to the USB host port on the formatter.
4. Turn on the product and follow the instruction on the Touch Control Panel.
Appendix C: Obtaining the product log and the diagnostics
package
The product keeps an internal log of its own actions. When a system error occurs, the product log can
help to find the cause and the solution. By default, whenever it restarts, the product deletes the current
log and starts a new one, to avoid using a lot of hard disk space. Once the logs have been captured,
the information can then be escalated to HP division for analysis.
Before retrieving the diagnostic package or product logs with the methods described next, you need to
enable the logs in the product. Follow the process described next to enable the logs.
Enabling the logs in the product
1. Turn off the product with the Power Key on the left of the Touch Control Panel.
2. Press and release the Power Key to turn on the product.
74 Chapter 2 System Error Codes ENWW
3. Wait for about 10 seconds until the 6 buttons on the Touch Control Panel come on and then press
and release one after another the RIGHT -> HOME buttons.
4. Wait for the unit to complete the booting process. The logs are now enabled in the product even if
the product hangs and shows a system error.
You can obtain the product log through the diagnostics package. There are two types of diagnostic
package:
●Diagnostic package (reduced level)
●Extended diagnostic package (full level)
And there are two ways of retrieving the information:
●From the Touch Control Panel with a USB flash drive (reduced level only)
●From the Embedded Web Server (reduced or full level)
NOTE: If the extended diagnostic package is available, it will be the only one visible from the
Embedded Web Server. In order to use the reduced diagnostic package from the Embedded Web
Server, you must disable the extended diagnostic package.
When you have obtained the information, it should be attached to the customer case.
Touch Control Panel method
This method works only if you have a standard USB flash drive. If you do not have a flash drive, use the
Embedded Web Server method. You are also recommended to use the Embedded Web Server if you
need the extended diagnostics package to solve a particularly difficult problem.
1. Take a standard USB flash drive, formatted as FAT32.
2. Create an empty file in the USB flash drive (right-click, New > Text Document) and name it
pdipu_enable.log. Then insert the USB flash drive into the product. Once the product recognizes
the USB, a short beep will be emitted.
3. The product starts to copy the diagnostic package to the USB flash drive. Wait for one or two
minutes. You may hear several short beeps for each file copied to the USB flash drive.
4. When you hear one long beep, that means the entire diagnostics package and the product log have
been copied to the USB flash drive. You can now remove the drive.
5. It will have created a folder with the name part number_serial number_time stamp, and in this folder
you’ll find one or more files with the extension trb. As the name of the folder contains the serial
number, you can reuse the flash drive for different products and the information will not be lost.
6. Disable the logs in the product after the diagnostic package has been retrieved. See Disabling the
logs in the product on page 76.
ENWW Appendix C: Obtaining the product log and the diagnostics package 75
Embedded Web server method
1. You can access the Embedded Web Server by typing the IP address of the product in a Web
browser. In the Support tab, click Service support to display the following page.
2. If the problem persists and is difficult to debug, try the extended diagnostics package. To enable
the extended diagnostics package, click Enable the extended diagnostics package. The product
needs to be restarted after enabling or disabling the extended diagnostics package.
3. At any time after enabling the extended diagnostics package, you can download the package and
the product logs by clicking Download the extended diagnostics package.
4. When you have finishing using the extended diagnostics package, remember to disable it;
otherwise it could affect product performance or even cause undesirable side-effects.
Retrieving logs without the diagnostic package
This method is recommended only if you are unable to use the diagnostic package for some reason.
1. Turn off the product with the Power key on the Touch Control Panel.
2. Enable logs, refer to Enabling the logs in the product on page 74.
3. After DO NOT REBOOT is displayed, retrieve at least the current product log from the following
URL: http://<IP>/hp/device/3432/8828/tmp/, where <IP> is the IP address of the product. Click the
file once to select it, then right-click and select Save target as.
4. The product.log file contains a log of the product activity since it was last restarted. Previous logs
are compressed and stored in .gz files whose names contain the date and time of the product
restart. You may wish to download some of these files as well.
5. Disable the logs in the product (see next).
Disabling the logs in the product
1. Turn off the product with the Power Key on the left of the Touch Control Panel.
2. Press and release the Power Key to switch on the product.
3. Wait for about 10 seconds until the 6 buttons on the Touch Control Panel come on and then press
and release one after another the RIGHT -> BACK buttons.
4. Wait for the unit to complete the booting process. The logs are disabled.

●Introduction
●Diagnostic Tests and Utilities
Introduction
This chapter explains how to use the product's diagnostic tests and utilities, and what to do in the event
of any failure.
NOTE: If possible, always perform a diagnostic test on a component that you are about to replace, to
make sure that is the component that has failed. If the test on that component passes, there is no need
to replace it.
Initialization Self Test
Initialization sequences
Whenever the product is switched on, it automatically performs a series of internal self-tests and
mechanical initialization sequences. If any part fails, a system error will appear and you should
consult System Error Codes on page 35.
Auto-Diagnostics Test
In the event of a paper or scan-axis jam triggering a system error 86:01 will be displayed.
After restarting, the product will exercise several electromechanical subsystems involved in Paper or
Scan Axis movement. If necessary, you may be asked to move the carriage manually or check whether
the main roller is moving. You may also be asked to launch an Auto-Diagnostics Test.
●In the event of a paper jam, if another paper jam occurs during the first 15 paper advance
movements after the product restarts, the product will ask you to launch the Paper Axis Auto-
Diagnostics.
●In the event of a scan-axis jam, if another scan-axis jam occurs during the first 50 carriage
movements after the product restarts, the product will ask you to launch the Scan Axis Auto-
Diagnostics.
A final result will be shown with all the collected data.
Phone Support
NOTE: In certain circumstances, a Call Agent can try to troubleshoot the product by requesting the
customer to perform a Service Test over the phone. Using this process, it can be determined whether
the product requires any on-site maintenance.
Remember that the key combination for the customer to enter the Service Tests and Utilities is different
from the one that the engineer will use.

Disk Wipe DoD 5220.220M
The purpose of this Service Utility is to erase data from the internal Hard Disk securely, according to
the directive DoD 5220.220M.
The product's hard disk is used as a temporary storage area for print jobs. The Secure Disk Wipe utility
can erase your information from the hard disk to prevent unauthorized access.
ENWW Service Utilities 129
Secure Disk Wipe provides three different levels of security:
●Insecure Mode: All pointers to the information are erased. The information itself is not erased,
and remains on the hard disk until the disk space it occupies is needed for new print jobs. The new
print information overwrites the old information. While the information remains on the disk, it is
difficult for most people to access, but may be accessed using software designed for that purpose.
This is the normal method in which files are erased on most computer systems; it is the fastest
method but the least secure. This is the default security level when using Secure Disk Erase.
●1 Pass Mode: All pointers to the information are erased, and the information itself is overwritten
with a fixed character pattern. This method is slower than Insecure Fast Erase, but more secure.
It may still be possible to access fragments of the erased information by using special tools to detect
residual magnetic traces.
●5 Pass Mode: All pointers to the information are erased, and the information itself is repetitively
overwritten using an algorithm designed to eliminate any residual traces. This is the slowest
method, but the most secure. Secure Sanitizing Erase meets the US Department of Defense
5220-220M requirements for clearing and sanitization of disk paper.

SCANdump
SCANdump is an archive file that can be viewed with SCANview (SCANtest). The SCANdump file
consists of the following:
●Four light profiles (see below for an explanation on Light Profiles).
◦RGB: Unadjusted.
◦RGB: Adjusted.
◦Grey: Unadjusted.
◦Grey: Adjusted.
●A statistic file and documentation about how to use the system.
Light Profiles
The light profiles are a snapshot of what the image sensor sees at the time the SCANdump was made.
The light profiles will in some degree be affected by of wear and tear, cleanness, and also the condition
of the calibration sheet that was used to calibrate the unit. There are two types of light profile, adjusted
and unadjusted.
The Unadjusted light profile is a raw picture of the light source. All imperfections of the sensors and the
light guide (in one, the CIS elements), are visible. Only the general light level has been manipulated.
The Adjusted light profile is corrected according to the calibration sheet, in other words, the calibration
sheet has been used as a reference to correct the imperfection of the CIS elements.
144 Chapter 4 Service Menu ENWW
Since we do the basic calibration in two modes, one for the color channels and one for Gray, two sets
of profiles are included in the SCANdump file.
General view of the light profile
This is the overview screen of the profiles of the CIS elements, here shown as A, B; C; D; E. Each arc
represents a CIS element. The lower half of the screen can be used to amplify the profile of a selected
CIS element, for a closer look.
Reading the Uncorrected Light Profile
A uncorrected light profile should be within the Min/Max shown here. Since the Light source is located
at the end of the CIS element it is normal that the light profile’s level is higher here and that the level
drops a little towards the center of the CIS.
ENWW Service Utilities 145
A white patch is located at each end of the CIS element. The one at the start of the CIS is a bit smaller
than the one at the end, it makes a black point, unlike the end which makes a Black and a White point.
Reading the Corrected Light Profile
A corrected light profile should be within the Min/Max shown here.
146 Chapter 4 Service Menu ENWW
Peaks will show up in a scan as a lighter color and not necessarily in all colors, it depends on which
color channels are being affected by the dirt/ scratch.
Drops will be seen as a dark line in the scan and again not necessarily in all colors, it depends on which
color channels are being affected by the dirt/ scratch.
If the peak or the drop is within 1-2 div (lines) it is usually not noticeable in the scan and is just general
noise. The dirt or the scratch can be from one pixel to several!
Statistics File
This file contains useful information about the usage of the system, along with firmware version and last
calibration date.
Troubleshooting image quality using the light profiles
A drop in the light profile is often caused by dirt/dust on the glass plate A spike is related to the calibration,
either dirt or dust on the glass plate during the calibration or a dirty calibration sheet.
A light profile with an about 20 pixel drop can be a contaminated lens in the CIS module.
ENWW Service Utilities 147
A light profile with an about 20 pixel drop can be a contaminated lens in the CIS module.
A completely flat light profile in one color or all colors can either be one specific LED or the entire CIS
module that is faulty.

9. Follow the next steps to calculate the Y-Axis adjustment scale: Measure the total length of the two
vertical rules at both sides of the copied plot (we call it M1 and M2).
NOTE: If M1 is quite different from M2 (more than 1mm or 1/16th inch) then refer to incorrect
paper advance, skew during scanning, or horizontal wrinkles in the Image-quality troubleshooting
guide on chapter 3, page 31 .
10. If M1 and M2 are similar (within 1mm or 1/16th inch) then consider M1 = M2 = M and calculate P
as: Y-Axis adjustment scale = -100 × ( M – T ) / T Where T is the total length of the vertical rules
(T = 22 inches or 57 mm). Follow the next steps to set the Y-Axis adjustment scale:
11. In the Service Utilities submenu, scroll to the Adjustment scanner Y-Axis scale and press on this
option.

NOTE: Before using this chapter to remove and install a new component, always make sure that you
have performed the relevant service test from Chapter 4. If the test passes you will not need to replace
the component.
Safety Precautions
Review the instructions identified by WARNING and CAUTION symbols before you service the product.
Follow these warnings and cautions for your protection and to avoid damaging the product.
NOTE: Serious shock hazard leading to death or injury may result if you do not take the following
precautions:
●Ensure that the ac power outlet (mains) has a protective earth (ground) terminal.
●Switch the product off, and disconnect it from the power source prior to performing any
maintenance.
●Prevent water or other liquids from running onto electrical components or circuits, or through

Customer Self Repair parts
Some product parts are designated Customer Self Repair (CSR) parts, which means that a faulty part
can be replaced by the customer. Non-CSR parts need to be replaced by an engineer. There are two
categories of CSR parts:
●CSR A: Customer self-repair is mandatory, as mentioned in the product's warranty statement. If
HP is asked to replace such parts, the customer will be charged for travel and labor costs. Parts
should be replaceable by end users (customers) from a mechanical perspective within 5 minutes,
with simple or no tools required. Examples include spindles and cartridges.
●CSR B: Parts are easy to replace, but some knowledge of the product and technical skills may be
required. The customer can decide whether to replace the part or to call for an engineer.
The CSR parts are listed below.

Cleaning the Product
To maintain the product in good operating condition, keep it free of accumulated dust, ink, and other
contamination. Cleaning intervals are determined by the product environment and by the types of
product supplies used.
General Cleaning
Proper general cleaning should include the following:
NOTE: To prevent an electric shock, make sure that the product is switched OFF and unplugged
before any cleaning is performed. Do not let any water get inside the product.
1. Blow away dust accumulation with compressed air if available.
2. Clean the outer surface of the product with a damp sponge or cloth. Use a mild soap and water
solution if necessary. Do not use abrasive cleaners.
3. Wipe the product dry with a soft lint-free cloth.
Cleaning the Drive Roller and Overdrive
NOTE: If ink is spilled on the Overdrive, remove the ink. Due to the ink's reflectance, ink on the
Overdrive can disrupt the product's edge-sensing function. To remove any ink from the Overdrive,
perform the following procedure:Prevent water or other liquids from running onto electrical components
or circuits, or through openings in the Electronics Module.
1. Perform the Turn Drive Roller Utility. See Turn Drive Roller on page 120.
2. Open the Scanner (MFP only) or Window.
436 Chapter 7 Preventive Maintenance ENWW
3. Apply any common household cleaning solution (water based only) to a soft, lint-free rag and apply
it to the Drive Roller and Overdrive surface while it is rotating. Make sure that you thoroughly clean
the Drive Roller and Overdrive surface.
4. Press Enter when you have completed the cleaning procedure.
5. Allow the Drive Roller to dry before loading paper in to the product.
Cleaning the Encoder Strip
1. Make sure that the product is not printing and that the Carriage Assembly is located at the Service
Station on the far right side of the product.
2. Using tap water and a small cloth that will not leave fibers in the product, dampen the cloth and
remove any excess water so that the cloth is damp but not wet.
3. Open the Scanner (MFP only) or Window.
ENWW Preventive Maintenance 437
4. Hold the cloth in an inverted “U” shape around the Encoder Strip and carefully wipe until no ink
residue appears on the cloth. Be very careful not to scratch the Encoder Strip with your fingernail
or any other object.
Make sure that you are holding the cloth correctly.
NOTE: Do not move the Carriage Assembly away from the Service Station.
5. Close the product Scanner or Window.

11. Turn the product back on.
Cleaning the Glass Plate
The customer is recommended to clean the glass plate periodically, depending on the usage of the
product. Keeping the glass free from smears, dust and dirt is an essential part of avoiding image quality
issues. If the customer complains of image quality issues, you can also clean the glass plate using the
following procedure.
1. Turn off the product using the power key at the front, then also turn off the power switch at the rear
and disconnect the power cable.
2. There is a small lever at the rear left of the scanner. Slide the lever to the right and open the CIS.

and then wrung dry. A suitable cloth is provided with the product.
CAUTION: Do not use abrasives, acetone, benzene or fluids that contain these chemicals. Do
not spray liquids directly onto the scanner glass plate or anywhere else in the scanner.
Do not worry about tiny droplets of water left on the glass: they will evaporate.
4. Optionally, for more thorough cleaning:
●Remove the glass plate and clean it on both sides. See Glass Plate on page 466.
●Clean the pressure rollers (between the feed rollers).
5. Close the CIS and gently push it down to lock it into place.

ENWW Preventive Maintenance 441
Carriage Assembly Lubrication
To ensure correct operation of the product you must lubricate the Carriage Assembly whenever any of
the following are encountered if:
●The Touch Control Panel displays "Maintenance #1 required".
●There is excessive noise when moving the Carriage Assembly.
●A shut down of the carriage PWM error message appears.
●There are IQ (vertical banding problems).
You should also lubricate the Carriage Assembly whenever you change any of the following service
parts:
●The Carriage Rear Bushing.
●The Carriage Assembly.
●The Carriage Rail Oiler.
To lubricate the Carriage Assembly you will require the Lubrication Kit (Q5669-60692). Use the following
procedure to lubricate the Carriage Assembly:
1. Use the IPA alcohol (Q6675-60070) and the cleaning cloth to clean the Carriage Rail and the
Carriage Slider Rod. Do not use IPA alcohol in California or other areas that restrict the volatile
organic compound (VOC) content of cleaning solvents. A regulatory compliant alternate should be
used.
2. Use an Oil Dispenser (Q6675-60062) to lubricate the Carriage Rail and the Carriage Slider Rod.
3. Replace the Carriage Rail Oiler on page 251 with the new one contained in the kit and add 2 or 3
drops of oil to the foam of the Carriage Rail Oiler.
4. Use an Oil Dispenser (Q6675-60062) to lubricate the Carriage Rear Bushing.
Moisture on the Product
Users should use the product in an environment between 20% and 80% relative humidity. To recover
from moisture condensation, turn the product Off, and, using the main roller as a reference, wait until
the product is completely dry before using it again.
Noisy Carriage Bushing
To prevent noisy movement of the carriage, remove aluminum or dust particles from the bushing at the
back of the carriage, and from the slider path along which the bushing moves. Lubricate the slider path
using the Lubrication Kit (Q5669-60692).
Belt Swelling
To prevent new belts from swelling incorrectly, keep them in their bags with desiccant until you need to
install them.
Level of Product Usage
Normal product use means 6,000,000 Carriage Cycles (which corresponds to approximately 100,000
A0 prints on average). Under normal usage conditions, it will be approximately 5 years before the product
needs maintenance. If the product is used more than the normal usage conditions, then it will need
maintenance service much more frequently.
One of the EEROM counters is assigned to counting the number of carriage cycles.
