Troubleshooting

code number. If the code number is 0, no error has been detected, if the last line displays a 

number from 1 to 6, this would indicate an error was found. 

Here are error code descriptions and the procedures to follow. 

Code1: The possible causes of this error code are: A dirty OMAS window, the substrate is not OMAS 

navigable or the substrate loaded is skewed or has wrinkles (visual inspection), incorrect substrate 

settings, failures of the vacuum system or Media input/Media output side plate. 

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. 

•

Redo the calibration, 4.3.4 Roller Calibration & 4.3.5 Check Roller Calib. 

•

Add new substrate process again for the substrate loaded (make sure there is not too much ten-

sion which would prevent a stable substrate advance). 

•

Check that the substrate loaded is the same as the substrate selected in the IPS. 

•

If the substrate seems stable when advancing it, and the substrate is OMAS navigable, this 

could indicate that the OMAS or Media Output is damaged: 
- Perform the OMAS service test (3.7) and replace OMAS if the test fails. 
- Perform the rear and front spindle test from the diagnostic mode (test 3.2 /3.3) with the spin-

dle installed, latches closed and no substrate loaded. If one of the test fails: 

1.

Grease the side plate gears (using oil from the cleaning kit) 

2.

Remove both spindles and perform the diagnostic test: ‘3.1 Spindle System Burning’. 

3.

Perform again the rear and front spindle test 3.2/3.3 with the spindle installed, latches closed 

and no substrate loaded. If the test fails replace the media input or media output side plate, 

depending on the failing test. 

•

Check Vacuum sensor tubes are correctly connected and perform from the diagnostic menu the 

‘3.6 vacuum system test’. 

Code2: Most probable cause of this error is the substrate has been loaded skewed or the diverter is not 

functioning correctly. 

Perform/check the following in the order, only move on to the next check when you are sure the error 

persists: 

1.

Reload the substrate correctly according to the instructions from the support documentation. 

2.

Unload the substrate, check that the diverter is turning freely, and reload substrate. 

3.

Collect the error file information using the HP retriever tool, by unchecking ‘only Service Page’, col-

lect the file information ‘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 error2 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. Do not replace the diverter if there is no 

evident failure of this part. 

Code3: Encoder disk of the drive roller may be damaged or wrongly assembled or there might be an 

issue with the driver roller: 

Perform/check in the following order, only move on to the next check when you are sure the error persists:
