Troubleshooting
When error 4 is displayed the printer can still work without any problems, however not all the
improvements from the new firmware will work, such as the substrate advance variability
reduction. The analyzes of the traces will confirm if there is any issue.
Code5: Cannot find the ‘zero position’ (system error 85:03) of the drive roller, this error can occur only
during the calibration check.
The zero position is calibrated by the printer each time that the printer is started, using a part of the
encoder disc of the drive roller, where there is a dark half circle.
Perform/check in the following order, only move on to the next check when you are sure the error persists:
1.
Check that the substrate loaded is the same as the substrate selected in the IPS.
2.
Unload the substrate and load it again. In case of ‘zero position’ failure, the following error is dis-
played on the front panel: ’85:03’.
3.
Carefully clean the encoder disk (scan beam has to be set to the high/loading position, the plastic
cover must be removed, and remove the cover protecting the drive motor, switch off the printer, turn
the shaft/coupling of the drive motor in order to rotate the drive roller).
4.
If it is still failing: unload the substrate, replace the encoder disk and encoder reader (support part
Q6702-60474Drive Roller Encoder Disc and Encoder PCA).
5.
After the replacement or cleaning, redo the calibration from service menu, entry 4.3.1. (no substrate
loaded)
6.
Check that the Vacuum sensor tubes are correctly connected and perform from the diagnostic menu
‘3.6 vacuum system test’.
7.
Redo the calibration, 4.3.4 Roller Calibration & 4.3.5 Check Roller Calib.
If it still fails for the same error: collect the error file using the HP retriever tool, Unchecking ‘only
Service Page’, collecting the file ‘logs.tar.gz<dateandtimeofextract>’ and escalate the case to HP
regional support team, asking them to escalate the case to the division, attaching the extracted file.
When error 5 is displayed the printer can still work without any problems, however not all the
improvements from the new firmware will work, such as the substrate advance variability reduction.
The analyzes of the traces will confirm if there is any issue.
Code6: The OMAS is seeing too much variation in the substrate advance, this error can happen only
during the calibration check.
Perform/check in the following order, only move on to the next check when you are sure the error persists:
1.
Use only OMAS navigable substrate that conforms to the characteristics described in step 1 in sec-
tion A.
2.
Unload substrate, clean the OMAS, reload substrate.
3.
In case of ‘zero position’ failure, the following error is displayed on the front panel: ’85:03’ -> check
the encoder disc and encoder reader of the drive roller.
4.
Check that the substrate loaded is the same as the substrate selected in the IPS.
5.
Redo the calibration, 4.3.4 Roller Calibration & 4.3.5 Check Roller Calib. If it still fails with the same
error:
•
Check that the pinch wheels are closed/down
•
Check Vacuum sensor tubes are correctly connected and run from the diagnostic menu ‘3.6
vacuum system test’.
