General troubleshooting
This chapter will guide you through the relevant steps to take when troubleshooting the printer.
Troubleshooting system error codes
System Error Codes on page 53 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 (See Note below).
● The Service Configuration Print.
● The Current configuration sheet.
● Which software application the customer is using (name, version, etc.).
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.
General troubleshooting 3
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.
Performing the necessary service calibrations
NOTE: Remember that certain Calibrations are required even if an Assembly has been disassembled to gain access to another Assembly or Component.
Solving print-quality problems
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.
The Front Panel is blank
The printer does not power on
The printer continuously rejects printheads
1. Clean the flex contacts on the Printhead and in the Carriage Assembly using the Carriage Interconnect Wiper 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 Module Test. See Electronics Module Test
Cover sensors are not working
2. Check that the cable for the faulty sensor is not damaged and is connected correctly.
3. Replace the faulty Sensor.
4 Chapter 1 Troubleshooting
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 printer and check that the Line sensor detects it.
Troubleshooting 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.
Banding at variable extreme environmental conditions
Since the Accuracy Calibration has been done at normal environmental conditions, printing in extreme environmental conditions will cause banding because the advance of the Media Advance 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).
Worm marks on HP Coated paper with light area fills
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 whether the humidity level is very low (below 30%). Increasing humidity may help in reducing the severity of the problem.
NOTE: The paper is causing the problem and not the printer. Do not attempt to try to replace printer parts to solve this problem.
General troubleshooting 5
The basket was damaged during printer setup
1. There are three plastic parts that could break during printer installation and need replacing.
Paper-handling troubleshooting
The Front Panel 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
Check that the Right Roll Support is properly attached and screwed to the printer.
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 printer, the Rewinder will not function properly.
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 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 printer.
If you have problems with paper jams, check that the Overdrive is not obstructed by bits of paper or
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 printer, the Rewinder will not function properly.
Print-quality troubleshooting
Print-quality troubleshooting actions
NOTE: For some print-quality problems, a Call Agent can try to troubleshoot the printer by requesting the Customer to perform certain actions. Using this process, most problems can resolved without the need of an on-site visit.
6 Chapter 1 Troubleshooting
When faced with a Print Quality problem, perform the following actions in order to resolve the problem:
1. Printer Configuration:
● Check that the paper type loaded corresponds to the paper type selected in the front panel and in the software. You can check the paper type selected by pressing the View information key on the Front Panel.
● Make sure that the correct Print Quality settings are used for different types of print content. See Print-quality troubleshooting actions on page 6 for further information.
● Dry time should be set to “Optimal”.
2. Perform Printhead recovery (Main Menu/Image Quality Maintenance/Clean Printheads).
● Select the correct paper type through the front panel when loading it.
● Make sure that HP or HP-approved paper is being used.
4. Perform the Printhead Alignment (Main Menu/Image Quality Maintenance/Align Printheads), using the same paper type with which you were experiencing unacceptable image quality, if feasible (some paper types are not suitable for Printhead Alignment).
5. Check whether the latest version of the firmware is installed. If not, install the latest firmware revision.
The Service Image Quality Diagnostic Print
What is the Service Image Quality Diagnostic Print?
The printer contains an internal Image Quality Test which helps you to diagnose the possible source of any image quality defects. The Service IQ Diagnostic Print is available in the following options:
1. Image Quality Service Best Plot. This plot helps you to diagnose in more detail the possible source of any image quality defects. It is accessible through the Service Utility Menu.
The Image Quality Service Best Plot uses the Best Print Mode and is divided in to three parts as follows:
● Diagnostic Part 1: Printhead Reliability Test. The purpose of this test is to identify which Printhead is faulty.
● Diagnostic Part 2: Printhead Alignment Test. This test is designed to check any color-to-color and bi-directional misalignment the printer may have.
● Diagnostic Part 3: Printheads and Paper Advance test. This test is designed to check whether the Printheads and the Media Advance Mechanism are working correctly.
2. Image Quality Service Normal Plot. This plot is the same as the Image Quality Service Best Plot but uses the Normal Print Mode.
Print-quality troubleshooting 7
Considerations for Printing the Diagnostic Print
1. The IQ Diagnostic Print prints in A3 and B sizes so you must have paper loaded (roll or sheet) that is this size or larger.
2. Use the same type of paper that the customer was using when they found the image quality problem.
3. If the customer is using non-HP paper and after the Image Quality Test you still have the same image quality problems, change to genuine HP paper and repeat the Image Quality Test.
If you do see problems with the Image Quality Test, continue with the Advanced Diagnostic procedures which will help you diagnose the problem.
Printing the Diagnostic Print
1. In the Service Utilities submenu, scroll to “Diagnostic Print” and press OK.
2. You will be given three options. Use the Arrow keys to make the selection and press the OK key to start printing the required Diagnostic Print or to enter the Advanced Diagnostics menu.
3. If you selected Advanced Diagnostics Print in the previous step, use the Arrow keys to make the required selection,and press the Enter key to start printing.
4. Make sure paper is loaded, the Media Lever is lowered and that the Ink System is correctly installed. Press the OK key to print the Diagnostic Print or press Cancel to exit without printing the Diagnostic Print.
5. The selected Diagnostic Print will now be printed.
Reading the Diagnostic Print results
Diagnostic Part 1: Printhead Reliability
8 Chapter 1 Troubleshooting
The Nozzle Print Test test is designed to check that the Printhead nozzles print correctly.
The nozzles check (top of the plot) is printed in a one-pass full swath mode. The diagnostics test prints out every single nozzle of each Printhead without applying an error hiding or alignment algorithm.
For each Printhead, you can see both the adjacent and the consecutive nozzles.
If any nozzles are not printing correctly they will be shown on the right of each Printhead Nozzle test. There is a series of numbered stepped diagonal lines. If one or more of the nozzles are clogged, malfunctioning or mis-positioned, you will see that the stepped lines are broken or misdirected in one or more places.
Below, the stepped lines highlighted in yellow are broken. When the line is completely broken, this means the nozzle is out.
Below, the stepped lines highlighted in yellow are misdirected. When the line is misdirected, this means the nozzle is malfunctioning or out of position.
On the left of each Printhead Nozzle test, there is a series of horizontal straight lines. If one or more nozzles are misdirected there will be unequal spaces between the corresponding lines.
If the printer has nozzle defects, you can still get perfect print quality results. The printer can automatically compensate for nozzle defects, so there is no need to replace the Printhead.
Print-quality troubleshooting 9
The method of improving Nozzle Defects is to:
1. Recover the Printheads, using the Front Panel Main Menu/Image Quality Maintenance/Clean Printheads option.
2. Reprint the Printhead Nozzles Test Plot to check that the defective nozzles have been corrected.
3. If the problem continues, replace the defective Printhead.
Diagnostic Part 2: Printhead Alignment
This test is designed to check any color-to-color and bi-directional misalignment the printer may have.
1. If the printer is experiencing horizontal misalignment problems, the Alignment Test will show something like this:
2. If the printer is experiencing vertical misalignment problems, the Alignment Test will show something like this:
10 Chapter 1 Troubleshooting
If the printer is experiencing bi-directional misalignment problems, the Alignment Test will show
something like this:
Perform the Printhead Alignment (Main Menu/Image Quality Maintenance/Align Printheads), using the same paper type with which you were experiencing unacceptable image quality, if feasible (some paper types are not suitable for Printhead Alignment).
Diagnostic Part 3: Printheads & Paper Advance
This test is designed to check whether the Printheads and the Paper Advance Mechanism are working correctly. This part of the Image Quality Test should not be used to check for color consistency or accuracy.
If the printer is experiencing a banding problem, you will see repetitive horizontal bands within the printed image.
● Darker horizontal bands or lines repeated along the vertical band (from top to bottom at the same distance).
● Whiter horizontal bands or lines along the vertical band (from top to bottom at the same distance).
The plot is printed in Best or Normal mode (according to the menu option selected) with Error Hiding ON. The top band has 100% ink density patches while the bottom band has 50% ink density patches.
Print-quality troubleshooting 11
Troubleshooting Banding Problems
If banding does not occur in all the colors, then it is more than likely a Printhead problem. In this case, try the following:
1. Check that the appropriate print quality settings are being used (refer to the User’s Guide for more information).
2. Recover the printheads using the option through the Front Panel (Main Menu/Image Quality Maintenance/Clean Printheads). Reprint the Diagnostic Print or the print file and if the problem persists, replace the faulty Printhead.
If banding does occur in all the colors, then it is more than likely a Paper Advance problem:
● If the bands are light, it means that the paper has advanced too much.
● If the bands are dark, it means that the paper hasn’t advanced enough.
● In high quality modes, graininess in all colors can indicate problems either with alignment or Paper Advance.
In order to solve problems that result in banding, try the following
1. Check that the appropriate print quality settings are being used (refer to the User’s Guide for more information).
2. Check that the loaded paper is the same type as selected in the printer. You can check the paper type selected through the Front Panel (Main Menu/Paper menu/View loaded paper).
3. If the customer is using low-quality paper, try recommending better-quality paper (preferably HP paper). Printer performance can only be guaranteed by using recommended papers.
4. Perform Paper Advance Calibration using the same type of paper that will be used for the final print (Main Menu/Image Quality Maintenance/Paper Advance Calibration/Calibrate Paper Advance).
If there is white point banding in only one color band and the problem cannot be fixed using the Printhead recoveries, in some cases using the Force Drop Detection option can fix this issue.
No Printing Defects Found in the Diagnostic Print
If all the test patterns from the Diagnostic Print are correct and you still experience Image Quality problems, you can use the following procedures to resolve the problem.
● Reading the Advanced Diagnostic Print Results
● Force Drop Detection
The Advanced Diagnostic Prints
What are the Advanced Diagnostic Prints?
These tests provide more information about the IQ defects found in the Image Quality Service plot.
12 Chapter 1 Troubleshooting
The Advanced Diagnostic Print is divided into the following parts:
● Visual Media Advanced Diagnostic. Used to check advance reliability.
● Printhead Alignment Diagnostic. Used to check pen alignment reliability.
● Visual Nozzle health Diagnostic. Used to check nozzle health reliability.
● Force Drop Detection. Used to reset the nozzle health historic database and force new drop detection.
Printing the Advanced Diagnostics Print
1. In the Service Utilities submenu, scroll to “Diagnostic Print” and press OK.
3. Use the Arrow keys to select the option you want, and press the OK key to start printing.
4. Make sure paper is loaded, the Media Lever is lowered and that the Ink System is correctly installed. Press the OK key to print the Diagnostic Print or press Cancel to exit without printing the Diagnostic Print.
5. The selected Advanced Diagnostic Print will now be printed and, if necessary, automatically scanned.
Reading the Advanced Diagnostic Print results
This plot helps you to visually check any alignment problems of the printer. You use it to precisely measure the paper advance error with a one dot row accuracy, and to check the stability of the paper advance.
Print-quality troubleshooting 13
NOTE: It is very important to check that the loaded paper is the same paper type as selected in the front panel. You can check the paper type selected through the Front Panel (Main Menu/Paper menu/ View loaded paper). The wrong type of paper selected will produce an offset error in the Paper Advance.
The following plot shows correct paper advance, there is a straight white line positioned close to the 0 column for the majority of the points.
14 Chapter 1 Troubleshooting
To fix Paper Advance problems, try the following:
1. Check the Paper Advance Calibration Status. This can be done by going to Main Menu/Paper/ View Loaded Paper. At the bottom, the Front Panel displays the Paper Advance Calibration status. There are three status messages:
● DEFAULT. The paper loaded is recognized as HP paper, which is already optimized and calibrated for the printer. Do not calibrate the Paper Advance for this paper.
● RECOMMENDED. The paper loaded is not recognized as HP paper, and Paper Advance values have not been customized for this paper type. In this case, calibrate the Paper Advance from the user menu.
● OK. This indicates that the paper loaded has been calibrated before. If the printer continues to have banding and graininess problems, calibrate the Paper Advance from the user menu.
NOTE: Whenever the printer’s firmware is upgraded, the paper advance calibration values will be reset to factory default.
2. To calibrate the Paper Advance from the user menu, go to Main Menu/Image Quality Maintenance/Paper Advance Calibration/ Calibrate Paper Advance.
NOTE: It is very important to check that the loaded paper is the same paper type as selected in the front panel. You can check the paper type selected through the Front Panel (Main Menu/Paper menu/View loaded paper). The wrong type of paper selected will produce an offset error in the Paper Advance.
NOTE: Some paper types are not suitable for Paper Advance Calibration. Do not use colored papers or transparent materials such as translucent bond, clear film, matte film, tracing paper, or vellum.
Paper Advance calibration from the user menu will only calibrate the Paper Advance for the paper type loaded in the printer at that moment.
3. If Calibrate Paper Advance has mostly solved the problem, try Adjust Paper Advance to fine tune the Paper Advance (Main Menu/Image Quality Maintenance/Paper Advance Calibration/
Adjust Paper Advance ).
4. The Paper Advance calibration from the service menu will calibrate the Paper Advance for all paper types. This action is recommended when:
● The Paper Advance calibration from the user menu does not solve the problem.
● The Paper Advance problems affect all paper types.
NOTE: To ensure you obtain meaningful results, use the same type of paper that the customer was using when they encountered the image quality problem.
