Printer education and training
Before any attempt is made to troubleshoot the printer, you must have the relevant training on the HP
Designjet Z6200/Z6600/Z6800 printer series. If you are not trained on these printers, please contact HP
Education or HP Training to enquire about becoming ‘HP Service Qualified’ for this printer.
Firmware update
The first step to take when trying to clear an error with the printer is to check that the firmware installed in
the printer is the latest available. Firmware updates often include fixes for common problems, and simply
updating the firmware can often resolve the problem. New firmware can be downloaded here:
http://www.hp.com/go/designjet/downloads
USB firmware update
If it is not possible to perform a firmware update using the Embedded Web Server (for instance, if the printer
has a System Error and the Embedded Web Server is inaccessible), it is still possible to do it using a USB flash
drive.
1. Turn off the printer.
2. Ensure that your USB flash drive contains a valid FMW firmware file and no other files.
3. Connect the USB flash drive to the USB host port on the Formatter.
4. Turn on the printer and follow the instructions on the front panel.
Forced firmware update
When the printer is started for the first time, it may automatically request a firmware update in order to fix
some known issues. You can respond in one of the following ways.
●
Use the USB flash drive provided in the box with the printer.
When a firmware update is requested, you should find a USB flash drive in the box, containing the new
FMW firmware file. Follow the instructions in the flier accompanying the USB flash drive.
NOTE: The USB flash drive is provided only to update the printer's firmware. No other uses of the USB
flash drive are supported.
NOTE: If the USB flash drive is not in the printer box, or fails to work properly, then download the
firmware instead.
●
Download the FWM firmware file from the HP Web site.
Store the file in a standard USB flash drive with no other files. Connect the flash drive to the formatter's
USB host port to perform the firmware update, following the instructions on the front panel.
●
Skip the firmware update.
If you cannot find the USB flash drive and you have no Internet connection, you can skip the forced
firmware update temporarily by pressing the OK key on the front panel three times, and the printer will
continue with the initialization sequence. Make sure that the firmware update is performed later. The
printer will request the firmware update every time that it starts, until the update is performed.
ENWW Printer education and training 3
Print-quality troubleshooting
Whenever a print-quality problem appears, it is advisable to print the Diagnostic Print to help diagnose the
problem. The Diagnostic Print will help you differentiate between possible printhead errors and other
problems such as incorrect front-panel selection, driver or RIP configuration or mechanical problems. For
more information on solving print-quality problems, see Print quality on page 155.
Troubleshooting system error codes
System error codes on page 43 contains a list of system error codes and their respective descriptions and
recommended corrective actions. Try only one recommended action at a time and check whether the error
code has disappeared.
If you have an error code which is not documented in this Service Manual or you have an error which 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:
●
Model and serial number of the printer.
●
Which firmware revision the printer is using (see Note below). Check firmware in Utilities / Statistics /
Code rev.
●
The complete error number.
NOTE: When reporting the system error code, make sure that you supply the full error code and the
firmware version. Without this information, HP support personnel cannot help you.
●
The service configuration print.
●
The current configuration sheet.
●
Which software application the customer is using (name, version, etc.).
Performing a service test on a failed assembly
If possible, always perform a Service Test on the component/assembly that you are about to replace, just to
make sure that is the component/assembly that has failed.
NOTE: If the test on that component/assembly passes, you should NOT replace it.
For information on the Service Tests and how to use them see Service tests and utilities on page 91.
Performing the necessary service calibrations
Is the printer calibrated correctly after replacing a component? For information on the Service Calibrations
and how to use them, see Service calibrations on page 131.
NOTE: Remember that certain calibrations are required even if an assembly has been disassembled only to
gain access to another assembly or component.
The printer does not power on
To resolve printer power-up problems, do the following:
4 Chapter 1 Troubleshooting ENWW
1. Check that the power cord is connected correctly to the printer and to the power socket.
2. Check that the power switch at the rear of the printer is in the on position.
3. Check that the front-panel cable is correctly connected to the Electronics Module. Also make sure that
the front-panel cable is not damaged.
4. Check to see if any of the LEDs on the power switch are on. If any of the LEDs are on, then see How to
read the power switch LEDs on page 18 for more information.
ENWW The printer does not power on 5
Incorrect Ink Cartridge troubleshooting
When the customer inserts an Ink Cartridge that is not compatible with the region for the printer the
following message is displayed:
If this is the first time that an incorrect ink cartridge of that color is inserted in the printer, the customer can
press OK to continue using that cartridge and the printer will use and finish the ink cartridge.
After the first time, the printer will reject all ink cartridges of the same color that do not match the selected
region of the customer (please refer to the Ink Cartridge family compatibility chart below).

In case of ink cartridge incompatibility do the following:
6 Chapter 1 Troubleshooting ENWW
1. Check the product family of the ink cartridge used. Make sure that product family matches the region
defined for the customer’s country (see the country list below).
2. Check the printer region set in the printer, and/or supplies, match the customer country
If the country is not properly set, correct the country as described in xxxx
With both the product family and printer region correctly set (see the compatibility chart above),
supplies will work.
As rejected ink cartridges will still work on printers that are compatible, ink cartridges are not replaced
by HP under warranty because of this type of mismatch.
Check the region and supplies compatibility
View compatible ink cartridge information by selecting the icon.
View the region setting in the Printer Information menu by clicking on the icon:
This information is also available in the Current Printer Configuration tab in the Embedded Web Server:
Change the printer region
The procedure to change the printer region is described in the User’s Guide. To change the printer region:
1.

4. Press the Cancel key and the Down key at the same time, and hold them down for at least two seconds.
The Printer will display the following message:
5. After selecting the Front Panel language, select the region for the ink cartridges.
6. The printer will show the selected region.
7. Press the Down key to view the countries in the region selected.
The complete list of countries can be found in the Appendix: Country lists on page 459 at the end of this
Service Manual.
8 Chapter 1 Troubleshooting ENWW
8. On confirmation, the Printer will display the the supplies that are compatible with the region selected.
Press the Back key to select a different region.
9. At the end of the process the printer will reboot.
After the region has been reset once, the Printer region cannot be changed again by the user. If the user
tries to change the region again, the Printer will display the following message with a Code.
Call agents need to raise a case with GBU through the GCC with the following information:
●
Code ID for Region Change of the printer
●
Printer Serial Number
●
Region to be set for this particular printer
●
Customer Name
●
Customer Address
10. GBU will provide an Ink Regional Code.
With the Ink Regional Code customers can proceed with region change.
The printer will show a screen to enter Ink Regional Code then:
Customers can select the character by pressing Upwith and Downarrows and selecting Ok. When the
Code is entered correctly, the customer selects the Return symbol and pressesOk
This will set the printer Region as requested by the Customer to the GBU.
If the code is not correct, the printer will display the following message:
The printer continuously rejects printheads
To resolve printhead rejection problems, do the following:
1. Clean the flex contacts on the Printhead and in the Carriage Assembly using the Carriage Interconnect
Wiper (see Carriage Interconnect Wiper on page 89) and try again.
2. If all the Printheads are rejected (for each Printhead, the status message on the Front Panel does not
show 'OK') then perform the Carriage Assembly Test Carriage Assembly test on page 98.
ENWW The printer continuously rejects printheads 9
A new maintenance cartridge is incorrectly detected as ‘used’
This can occur if the printer has detected the previous Maintenance Cartridge was nearly full, and when a new
Maintenance Cartridge is installed the front panel displays an error that the cartridge is ‘used’. To resolve the
problem, manually reset the counter of the Maintenance Cartridge Reset Life Counters on page 116.
Cover sensors are not working
To resolve cover sensor problems, do the following:
1. Check whether the sensor cable is damaged or not connected correctly.
2. Replace the faulty sensor.
The Line Sensor has problems detecting paper
To resolve Line Sensor paper detection problems, do the following:
1. Check the type of paper that is being used: the Line sensor may have problems detecting transparent
paper or some types of Non-HP paper. Try loading white HP paper into the printer and check whether
the Line Sensor detects it.
2. Excessive ink deposits on the Platen surface can fool the sensor by reflecting the light. Clean the Print
Platen.
3. Clean the Encoder Strip See Clean the Encoder Strip on page 450.
4. The Line Sensor is not calibrated correctly. Perform the Line Sensor Calibration See Line Sensor
calibration on page 139.
5. The Line Sensor is damaged or faulty. Replace the Line Sensor See Line Sensor Assembly
on page 379.
Troubleshooting paper jams and printhead crashes
NOTE: If you were using HP Coated Paper when the problem occurred, see also Printhead crashes/smears
on high-density prints using coated paper on page 13.
Paper jams and printhead crashes 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, which means that many paper jams are reported
as printhead crashes.
10 Chapter 1 Troubleshooting ENWW
Question Answer
Did the paper jam occur when loading paper? If paper jams have occurred previously, some pieces of paper may
still be stuck in the paper path. Clear the paper path.
NOTE: Customers often store used rolls without protecting
them from office environmental conditions; when exposed to
high humidity, the paper edges tend to curl. This curling can
cause paper jams when paper is loaded by feeding paper in
without lifting the Media Lever. In these conditions, to avoid
paper jams, the recommendation is to load paper by lifting the
Media Lever and aligning the paper manually, following the
instructions on the front panel.
Is the customer using non-HP paper? The use of non-HP paper can easily be the cause of paper jams
and printhead crashes—especially printhead 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 if the problem is
now solved.
TIP: 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.
Troubleshooting paper, scan axis and Rewinder Motor shutdown
If a shutdown occurs, you will get the message “Switch Power Off” followed by one of these messages:
●
Check Maintenance Cartridge Path
●
Check Paper Path
●
Check Printhead Path
NOTE: A shutdown in each path will require different steps to resolve the problem as explained below. In
each case, make sure that you power off the printer before trying to resolve the problem.
Also check that the Rewinder Motor moves easily (without friction) with the printer turned off.
Maintenance cartridge path
Open the right door of the printer and check for any visible obstacles restricting the movement of the Service
Station. Manually move the Service Station, checking for smooth and free movement.
Paper path
To resolve paper path problems, do the following:
1. Open the Window and check for any visible obstacles restricting the movement of the Drive Roller. Make
sure that the mylar is not damaged. If there is a wrinkled mass of paper inside the paper path, lift the
Pinch wheels (using the Paper Load Handles) and clear the obstruction.
2. If this shutdown happens at the end of a Roll of Paper, it could be because the paper is stuck firmly to
the Roll. Lift the Pinch wheels (using the Paper Load Handles) and pull the paper clear.
ENWW Troubleshooting paper, scan axis and Rewinder Motor shutdown 11
3. Replace the spindle if broken.
4. Perform the Paper Drive Test to obtain further information on the problem Paper Drive test
on page 94.
Printhead path
When a shutdown occurs in the Printhead path, you will get the message “Switch Power Off / Check Printhead
Path (*). The (*) will be a number, which will give an indication on where the failure occurred.
PWM shutdown
To resolve a PWM shutdown, do the following:
1. Clean Slider Rods and Apply Oil along the complete axis of the Slider Rods. After applying the Oil,
perform the Scan-Axis Test See Scan Axis test on page 94 and check that the values are within the
given limits.
2. Clean the Encoder Strip See Clean the Encoder Strip on page 450.
3. Perform the Scan-Axis Test to obtain further information on the problem Scan Axis test
on page 94.
Velocity shutdown
To resolve a velocity shutdown, do the following:
1. Open the Window and check for any visible obstacles restricting the movement of the Carriage
Assembly. Try and move the Carriage Assembly manually, checking for smooth and free movement.
2. Check that the Encoder Strip is clean. If necessary, clean Encoder Strip using a damp cloth.
Energy shutdown
To resolve an energy shutdown, do the following:
1. Clean Slider Rods and Apply Oil along the complete axis of the Slide Rods. After applying the Oil,
perform the Scan-Axis Test See Scan Axis test on page 94 and check that the values are within the
given limits.
2. Clean the Encoder Strip See Clean the Encoder Strip on page 450.
3. Perform the Scan-Axis Test to obtain further information on the problem Scan Axis test
on page 94.
Vacuum suction much lower at high altitudes
At altitudes above 3,000 meters, the vacuum force holding down the paper will be lower, therefore the paper
will not be held in place properly causing:
●
Ink Smearing on the Paper.
●
Printhead crashes against the Paper.
●
Roll Paper loading problems (low probability).
12 Chapter 1 Troubleshooting ENWW
Banding at variable extreme environmental conditions
NOTE: This problem is only applicable if the OMAS is disabled.
Since the Accuracy Calibration has been done at normal environmental conditions, printing in extreme
environmental conditions will cause banding because the advance of the Drive Roller does not correspond to
the same conditions that the calibration was done in. To solve the problem, try the following:
Perform the Accuracy Calibration in the new environmental conditions (see
Using your printer).
Printhead crashes/smears on high-density prints using coated paper
High-density prints can cause cockle mainly on HP Coated Paper. This causes two main problems:
. Cockling in the borders - Because the printer places too much ink on the Coated Paper, the borders of
1
the print become raised, causing the Printhead to crash against the paper. To solve the problem, add a
15 mm white margin to the edges of the images.
. Cockling within the print - If the printer places too much ink within the print, the paper starts to ripple,
2
causing the Printhead to smear against the paper. To solve the problem, try the following:
●
Check in the Front Panel if
●
Avoid using HP Coated Paper for high-density prints. As a substitute, use HP Heavyweight Coated
Paper.
Ink Limiting is ON or OFF. If Ink Limiting is OFF, turn it ON.
Banding due to ink cartridge replacement while printing
Someone has removed an Ink Cartridge while the printer was printing, which has caused the printer to stop. If
the user does not replace the Ink Cartridge immediately, when the printer starts to print again, a band will
appear in the position where the printing restarted. This is because the wet ink interacts with the dried ink on
the paper causing the band to appear. To solve the problem, try the following:
●
Do not remove an Ink Cartridge while the printer is printing. Only replace/remove Ink Cartridges
between prints.
●
If the Ink Cartridge was replaced due to the “Empty” status on the Front Panel, then advise the
customer to replace the Ink Cartridge when the “Very Low” status is showing on the Front Panel.
●
Reprint the file (without removing the Ink Cartridge).
34-inch Rice Paper not supported
The roll width is 34 inches (non-standard), and the pinch wheels can't control the edge of the paper, causing
ink smears and printhead crashes.
Worm marks on HP Coated Paper with light area fills
Light bands (S-shaped) in the direction of the media axis when light area fills are printed, causing an
unacceptable print-quality defect.
ENWW Banding at variable extreme environmental conditions 13
●
Print the Service Configuration Print and check whether the ambient humidity is very low (below 30%).
Increasing humidity may help to reduce the severity of the problem.
NOTE: The paper is causing the problem and not the printer. Do not attempt to replace printer parts to
solve this problem.
Solving paper-handling problems
The front panel keeps indicating 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.
NOTE: Ensure that the paper is wrapped tightly on the roll. This is a very important step to remember
because if this is not done, the paper may be loaded at an angle, causing the paper to be rejected.
●
The Line Sensor may be malfunctioning. See The Line Sensor has problems detecting paper on page 10.
Difficult to load paper: “Too much skew”
If you encounter a high failure rate when loading paper and the Front Panel reports “Too Much Skew” it is
likely that:
●
The encoder strip must be cleaned (this can be carried out by the customer using the User Maintenance
Kit).
●
The Line Sensor must be cleaned.
●
The Blue Line calibration must be performed. See Platen blue line calibration on page 148.

Checking the Take-Up Reel is correctly installed
Many system error codes are displayed as a result of the Take-Up Reel not being installed correctly or
because parts have moved or become dislodged from their correct positions. This troubleshooting procedure
checks the mechanical installation of the Take-Up Reel.
. Check that the Take-Up Reel sensor unit is correctly installed on the right foot.

4. Check that the Take-Up Reel motor assembly is correctly connected to the rear of the printer.
How the Take-Up Reel works
When selecting the front panel's Paper menu, if there is no line Take-Up Reel installed, this indicates that
the Take-Up Reel has not been enabled at the front panel. This does not mean that the Take-Up Reel will not
work; it just means that, if there is a paper jam detected by the Take-Up Reel, there will be no warning
system error displayed on the front panel. The printer will not stop.
How to install the Take-Up Reel
From the Paper menu > Take-Up Reel > Enable Take-Up Reel. After this is done, you will notice the following
differences:
●
In case of Take-Up Reel Paper jam system error, a warning is reported on the front panel, and the
printer pauses.
●
The cutter is disabled between jobs.
●
When unloading the paper, the front panel will ask you to cut the paper manually.
How it works
When the bottom of the 'loop shaper' is low enough and it cuts the signal between the two sensors, the TakeUp Reel starts to move the motor until the signal between the two sensors is passing through again.
If, after a few seconds of turning the Take-Up Reel, the signal between two sensors is still cut, the Take-Up
Reel reports a 'Take-Up Reel paper jam' error:

In all cases, the LED of the Take-Up Reel is blinking quickly.

If the Take-Up Reel is enabled at the front panel, a Take-Up Reel paper jam will be displayed.

How to read the power switch LEDs
In certain circumstances, the LEDs located on top of the power switch (located at the rear of the printer)
indicate the status of power supply to the printer.
1. When only the Amber LED is On:
●
The printer has been switched Off from the Front Panel (after having pressed the On/Off button).
●
The Power Supply Unit only delivers a 5 V “Standby”; power that is needed to restart the printer
after the Front Panel On/Off button is pressed (the Formatter will start the printer).
2. When the Blue LED is On: Deliver standard “ATX” power for the Electronics Module PCAs (+12V, +5V,
-5V, -12V, etc...). All the functions of the Electronics Module are fully operational (EWS, etc...).
3. When the Green LED is On: Deliver “analog” 24V and 36V to enable printing.
If you turn on the printer at the front panel, and the Blue LED does not come on, there is a problem. Turn off
the printer using the switch at the rear, then turn it on again using the same switch. If the Blue LED still does
not come on, replace the Power Supply Unit.
If the Blue LED comes on this time, you will probably see an error reported on the front panel as the printer
starts up. If no error is reported, but you continue to have problems when turning on the printer from the
front panel, see How to read the Formatter LEDs on page 19.

How to read the Formatter LEDs
The LEDs located on the Formatter can help to troubleshoot the printer. The LEDs can either be on or off;
different combinations can indicate different problems.
The following image shows the three Formatter LEDs, which are numbered from the top down: number I at
the top, number II in the middle, number III at the bottom.
Use the following table to interpret the LEDs and find the source of the problem. Remember that you should
read these LEDs when you push the
Power button.
Some combinations may require you to replace two or more components. In this case, always replace one
component at a time. Test the printer to see if the problem has disappeared (check the LEDs again). If the
same LED sequence continues, replace the next component indicated in the table.
