6.

Perform the rear and front spindle test from the diagnostic mode (test 3.2 /3.3) with the spindle 

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

•

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

•

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

•

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. 

•

Redo the check of the drive roller. 

If it still fails with the same error: Redo the calibration of the drive roller, and after the check of the drive 

roller. 

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 6 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. 

You need to print a specific file without out using any color management. This file can be obtained from 

the support zone, under the section: Commercial Prod., L65500, Machine configuration, and download 

the file 

smallverticallineblack_magentalast.tif

. HP IPS\Advance Calibration file is available from the IPS 

menu c:\Users\<current logging>\documents\, and the job name will be: 

substrateadvancecheck_300dpi.

When printing this do not use any color management, in order to make sure that the lines are printed with 

black or magenta color only. 

Once ripped, you can nest the image where the customer suspects the media advance issue, placing this 

ladder in EACH side of the image. 

When you print it, you will be able to fine-tune the media advance, to align the magenta and black line. 

The variation will then be visible. A small variation can all the time be possible. As a first rule, as long as 

the magenta and black are still touching, the printer is within specification. 

Also, do not hesitate to fine-tune the substrate settings (tensions, temperature, vacuum). 

The general rule: as long as there is no space between the black line and the magenta line (horizontal 

axis only), then there is no specific issue. If you have any doubt, we recommend printing the same
