Troubleshooting
Refer to Section 6 for troubleshooting Image Qulaity issues.
Before any attempt is made to troubleshoot the printer, it is critical that you have the relevant training on the HP Designjet Z6100 Printer series. If you are not trained on this printer, please contact HP Education or HP Training to enquire about becoming ‘HP Service Qualified’ for this printer.
The first step to take when trying to clear an errror with the printer is to check that the firmware installed in the printer is the latest available. Firmware updates often include fixes for some of the problems that are found in the following pages, simply updating the firmware can often resolve the problem. New firmware can be downloaded from the following url: http:www.hp.com/go/designjet/downloads
If the error with the printer does not allow you to upgrade the firmware using the normal process, try upgrading the firmware using the emergency .plt file procedure page 130
Chapter 2, System Error Codes contains a list of system error codes and their respective descriptions and recommended corrective actions. Only try one recommended action at a time and check if 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.).
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 Chapter 4, Service Tests and Utilities.
2 Chapter 1 Troubleshooting
Is the printer calibrated correctly after replacing a component? For information on the Service Calibrations and how to use them see Chapter 5, Service Calibrations.
NOTE: Remember that certain Calibrations are required even if an Assembly has been disassembled to gain access to another Assembly or Component.
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 information on solving Print Quality problems see Chapter 6, Print Quality.
To resolve printer power up problems, do the following:
1.Check that the power cord is connected correctly to the Printer and to the Power Socket.
2.Check that the Power Switch on the BACK of the Printer is in the ON position.
3.Check to see if any of the LEDs on the Power Switch are On. If any of the LEDs are On, then refer to See page 15 for more information.
4.Check that the Front-Panel Cable is correctly connected to the Electronics Module. Also make sure that the Front-Panel cable is not damaged.
5.Replace the CPU Fan See page 371
6.Replace the Power Supply Unit See page 379.
It has been seen under certain circumstances that the printer hangs whilst printing, this may happen immediately after printing, or only a partial print. In some cases when this occurs if the machine is rebooted a system error 79:04 is displayed, although rebooting again appears to clear this error. After this point, although the printer displays that it is in the “Ready” state, attempting to print anymore plots will once again hang the printer, including internal demo plots.
Reason
The reason for this error is that a large spooled file (11Gb for example) has been sent to the printer and has been placed in the disk partition which is related to the print queue. The file completely fills up all the disk space, because of this it will never successfully print, and so the file remains in the disk partition.
Even after restarting the printer the file remains, subsequent print requests also fail as there is not sufficient space available in the partition to process anything else.
Solution
Perform the following few steps to clear the error.
Troubleshooting
Performing the necessary service calibrations |
3 |
Troubleshooting
1.Check that the firmware is the latest available (at least 7.0.03)
2.Turn Off and ON the printer.
3.Set Queue to OFF.
4.Set ‘When Start Printing’ to ‘Immediately’.
Please guide the customer through the front panel of the printer to set up the “Queue” to “OFF” and “When Start Printing” to “Immediately”.
Wipe disk solution
If the above procedure does not clear the error, use the wipe the hard disk procedure (Unsecure mode)See page 145. This will delete all previous jobs, ICC profile, media profiles that were present on the hard disk. This procedure has an advantage for the customer in that it solves the issue without the need to wait for an onsite engineer to come to their premises and remove and replace the HDD (which would also have the same affect of deleting all the previous jobs, ICC profiles and media profiles). The whole procedure should not take more than 30-35 minutes.
Important step is that you need to select the Unsecure mode
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 (Refer to Chapter 3) and try again.
2.If ALL the Printheads are rejected (the status message on the Front Panel does NOT show “OK” for ALL the Printheads) then perform the Electronic Systems Test See page 105.
This can occur if the printer has detected the previous Maintenenace Cartridge was nearly full, and when a new Maintenenace Cartridge is installed the Front Panel displays an error that the cartridge is ‘used’. To resolve the problem, do the following:
1.Ensure the firmware installed in the printer is the latest available.
2.Once the latest firmware is installed repeat the Maintenance installation procedure with the same cartridge.
3.Manuall reset the counter of the Maintenance Cartridge See page 138
To resolve cover sensor problems, do the following:
1.Perform the Sensors Test See page 112.
2.Check if the cable for the faulty sensor is not damaged and is connected correctly.
3.Replace the faulty Sensor.
4 Chapter 1 Troubleshooting
To resolve line sensor media detection problems, do the following:
1.Check the type of media that is being used since the Line sensor may have problems detecting transparent media or some types of Non-HP media. Try loading white HP media in to the Printer and check if the Line sensor detects it.
2.Excessive ink deposits on the Platen surface can fool the sensor by reflecting the light. Clean the Center Platen.
3.Clean the Encoder Strip See page 454.
4.The Line Sensor is not calibrated correctly. Perform the Line Sensor Calibration See page 163.
5.The Line Sensor is damaged or faulty. Replace the Line Sensor See page 390.
NOTE: If you are using HP Coated Media when the problem occurred, please also refer to Page 1-6.
The failure modes “media jam” and “head crash” are grouped together because in many cases a media jam causes the media to lift up into the Carriage path and cause a Printhead crash, thus causing many media jam failures to be reported as head crashes.
1.Did the media jam occur when loading media?
NOTE: When clearing a media jam, sometimes media is stuck in the paper path. To clear this, you must lift the Media Lever and insert thicker media into the paper path to push out the media that is still stuck there.
•If the client has had media jams, it is common for pieces of media to get stuck in the media path. Clear the media path.
2.Is the customer using non-HP media?
•The use of non-HP media can easily be the cause of media jams and head crashes (especially head crashes because HP media is specially formulated to avoid cockle, one of the primary causes of head crashes). If the media is not HP approved, advise the customer to use HP media and check to see if the problem is now solved.
3.Check that the Vacuum Fan works correctly.
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.
Troubleshooting

Troubleshooting
•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 attempting any procedures to resolve the problem.
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.
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 media inside the paper path, lift the Pinch wheels (using the Media Load Handles) and clear the obstruction.
2.If this shutdown happens at the end of a Roll of Media, it could be because the media is stuck firmly to the Roll. Lift the Pinch wheels (using the Media Load Handles) and pull the media clear.
3.Replace media spindle if broken.
4.Replace the Media-Axis Motor See page 349.
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:
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 page 97 and check that the values are within the given limits.
2.Clean the Encoder Strip See page 454.
3.Replace the Scan-Axis Motor See page 346.
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.
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 page 97 and check that the values are within the given limits.
2.Clean the Encoder Strip See page 454.
6 Chapter 1 Troubleshooting
3.Replace the Scan-Axis Motor See page 346.
At altitudes above 3,000 meters, the vacuum force holding down the media will be lower, therefore the media will not be held in place properly causing:
•Ink Smearing on the Media.
•Printhead crashes against the Media.
•Roll Media loading problems (low probability). PRINTER LIMITATION - NO SOLUTION AVAILABLE.
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 (Refer to the User’s Guide).
High density prints can cause cockle mainly on HP Coated Media. This causes two main problems:
1.Cockling in the borders - Because the printer places too much ink on the Coated Media, the borders of the print become raised, causing the Printhead to crash against the media. To solve the problem, try the following:
•Change the paper margins to 15mm, either in the Front Panel or in the Driver. If the customer is printing PostScript images, send them a PPD file containing the extended margins of 15mm.
2.Cockling within the print - If the Printer places too much ink within the print, the media starts to ripple, causing the Printhead to smear against the media. To solve the problem, try the following:
•Check in the Front Panel if Ink Limiting is ON or OFF. If Ink Limiting is OFF, turn it ON.
•Never use HP Coated Media for High Density prints. As a substitute use HP Heavy Coated Media.
A user has removed the 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 media causing the band to appear. To solve the problem, try the following:
Troubleshooting
Vacuum suction much lower at high altitudes |

Troubleshooting
•Do NOT remove the Ink Cartridge while the Printer is Printing. Only replace/remove Ink Cartridges in 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 remove the Ink Cartridge).
Roll length is 34" (Non-standard) and the pinch wheels can't control edge of media causing ink smears and Printhead crashes in middle of prints with or without area fills.
PRINTER LIMITATION - NO SOLUTION AVAILABLE.
Light bands (S-shaped) in Paper axis direction where light area fills are printed, causing unacceptable Image Quality defect.
•Print the Service Configuration Print and check if the level of Humidity is very low (below 30%). Increasing humidity may help in reducing the severity of the problem.
NOTE: The media is causing the problem and NOT the Printer. Do not attempt to try and replace Printer parts to solve this problem.
The Front Panel Keeps Indicating that Media 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 media may be loaded at an angle, causing the media to be rejected.
If you encounter a high failure rate when loading media 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 “8. Platen Blue Line Calibration” on page 177).

Troubleshooting
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 machnical installation of the Take Up Reel.
1.Check that the Take UP Reel sensor unit is correctly installed on the right foot.
2.To correctly install the foot, the wheel has to be positioned as shown.
3.Check the cables linking the sensors to the Take Up Reel Motor Assembly are correctly connected.
4.Check that the Take UP Reel motor assembly is correctly connected to the rear of the printer.
10 Chapter 1 Troubleshooting
There are two different setups:
1.The Take Up Reel has been installed via the front panel from the media menu – how to check it: If the words 'Take Up Reel installed' is blanked out, this means that the Take Up Reel is not installed in the front panel.
2.The Take UP Reel has not been install via the front panel – how to check it: When selecting the media menu, there is no line ‘Take Up Reel installed’. 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 Media menu -> Take Up Reel -> Enable Take Up Reel. The main differences between the two modes (Take Up Reel installed or not installed on the front panel), what will happen if the Take Up Reel is installed:
•In case of Take Up Reel Paper jam system error, a warning is reported on the front panel, and the printer is no more printing (pause)
•The cutter is disabled between jobs
•When unloading the media, the front panel will ask you to manually cut the media.
How it works?
When the bottom of the 'loop shaper' is lower enough and it cuts the signal between the 2 sensors, the Take Up Reel starts to move the motor until the signal between the 2 sensors is passing through again.
If after the 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 case, the LED of the Take Up Reel is blinking quickly
•and if the Take Up Reel is enabled on the front panel, a 'Take Up Reel' paper jam will be displayed.
When the Printer is powered up, it doesn’t make a “Beeping Sound” until it is completely powered-up and ready to use. If there is a beep during the power-up sequence, this may signify that there is a problem within the Electronics Module. The following table will help you to use the “Beeping Sound” to diagnose certain problem:

To resolve power-up problems, use the following corrective actions:
1.If the Printer's Power-Up process stops when the front panel is displaying the number 17, this indicates that there is a problem with the file system on the Printer's Hard Disk Drive, so the Printer is checking the whole file system and making any necessary corrections. This problem can arise when there has been a power cut while the Printer was switched On, or if there is a physical problem with the Hard Disk Drive.
Checking the whole file system normally takes about half an hour (but could take much longer). There is nothing that can be done to speed up the file checking process. If you turn Off the Printer during the checking process, the file system check will restart whenever you turn it On again.
If you experience this problem repeatedly when there has been no power cut, then this could mean that the Hard Disk Drive is faulty. In this case, replace the Hard Disk Drive See page 377.
2.If the printer's start-up process stops when the front panel is displaying any number between 1 to 30, then try the following:
•Switch the Power OFF from the back of the Printer and disconnect the Power cord. Reconnect the power cord and power On the Printer.
•If the Printer continues to stop during the power-up process, replace the Hard Disk Drive See page 377.
A problem with the OMAS board may cause the printer to display a 50.2:10 service error, this can be fixed by checking the following connections.
1.Check the CAN Cable is correctly connected.
14 Chapter 1 Troubleshooting
2.Check the other end of the CAN cable is also correctly connected
3.Check the LEDs under the OMAS board.
This LED only comes on for the first 20 seconds after the printer is turned On. When the firmware has succesfully loaded into the memory the LED will switch OFF.
These LEDs come On and stay lit. From right to left:
1st LED=24 volts
2nd LED=5 volts
3rd LED=3.3 volts
Troubleshooting
In certain circumstances, the LEDs located on top of the power switch (located at the rear of the Printer) can help to troubleshoot the Printer. The LEDs can either be ON or Off and using different combinations can indicate different problems:
Amber is on the Left
Blue is in the center
Green is on the Right
Make sure you look directly at the LEDs and not at an angle.

In certain circumstances, the LEDs located on the Interconnect PCA and PrintMech PCA can help to troubleshoot the Printer. The LEDs can either be ON or Off and using different combinations can indicate different problems.
The following illustration shows the locations of the LEDs on the Interconnect PCA
DS1: 24V
DS4: VPOWER2 DS5: 5V
DS3: 5Vsb
Interconnect PCA
5V - Comes from the PSU after the fuse on Interconnect PCA. Used to power On Front Panel and some Interconnect Electronics. Should be ON at the same time as Blue Power Switch LED.
5Vsb - Comes from the PSU after the fuse on Interconnect PCA. Used to power On the Printer from the Front Panel. Should be ON at the same time as Blue or Amber Power Switch LED.
16 Chapter 1 Troubleshooting
24V - Comes from the PSU after a fuse on the PrintMech PCA.
VPOWER2 - Comes from the PSU (42V) after a fuse on the Interconnect PCA. Used to power the Carriage PCA. Should be ON at the same time as Green Power Switch LED.
The following illustration shows the locations of the LEDs on the PrintMech PCA.
DS7: 5Vsb
DS5: VAUX=12V
DS4: 24V
DS3: VPOWER2
