HP Z6200 plotter repair large format printer repair troubleshooting guide

This article describes the types of problems that are often encountered when repairing the HP Z6200 Large Format Printer Plotter, and the steps you need to take to resolve the problem. Such as print quality problems, service calibration problems, paper jams, sensor problems.

1:print quality troubleshooting

Whenever there is a print quality problem, it is best to print a diagnostic print to help diagnose the problem. Diagnostic printing will help you distinguish between possible printhead errors and other issues, such as incorrect panel selection, driver or RIP configuration or mechanical problems.

2:Troubleshooting — Troubleshooting System Error Codes

The system error code contains a list of system error codes and their respective descriptions and suggested corrective actions. Try only one suggested action at a time and check if the error code has disappeared.
Perform service testing on failed components
If possible, always perform a service test on the component/assembly to be replaced to ensure that the component has expired.
Note: If the component passes the test, it should not be replaced.
For service testing and how to use them, see Service Tests and Utilities.

3: perform the necessary service calibration
Is the printer calibrated correctly after replacing components? For service calibration and how to use them, see Service Calibration.
Note: Keep in mind that some calibration is required even if you remove a component just to access another component or component.
4: the printer did not boot
To resolve printer power issues, perform the following steps:
1. Check that the power cord is properly connected to the printer and power outlet.
2. Check if the power switch on the back of the printer is on.
3. Check that the front panel cable is properly connected to the electronic module. Also make sure the front panel cable is not damaged.
4. Check if there is a led light on the power switch. If any of the led lights are on, please refer to the service manual power switch led for more information.

6: the printer constantly rejects the print head
To resolve the printhead rejection issue, perform the following steps:
1. Use the slider interconnect screed to clean the telescopic contacts on the printhead and slider assembly and try again.
2. If all printheads are rejected (for each printhead, the status information on the front panel does not display “OK”), then the carriage component test is performed.
7: a new maintenance cartridge is incorrectly detected as “used”
If the printer detects that the previous maintenance cartridge is almost full, and when a new cartridge repair cartridge is installed, the front panel shows an error and the cartridge is ‘used’. To resolve this issue, manually reset the life counter.

8: the cover sensor does not work
To solve the problem with the top cover sensor, perform the following steps:
1. Check the sensor cable for damage or improper connection.
2. Replace the defective sensor.
9: the line sensor detects paper problems
To solve the problem of line sensitive paper detection, please do the following:
1. Check the type of paper you are using: The line sensor may have problems detecting transparencies or certain types of non-hp paper. Try loading white HP paper into the printer and checking if the line sensor detects it.
2. Excessive ink deposits on the surface of the plate can deceive the light reflected by the sensor. Clean the print roller.
3. Clean the encoder strap.
4. The line sensor is not properly calibrated.
5. The line sensor is damaged or malfunctioning.
