Troubleshooting

The printer has eleven service prints available to define and resolve image quality problems. If it is 

possible to identify the problem using a service print, as a matter of best practice, you should reprint the 

service print after taking action until the problem is solved.

The following user prints are available and fully documented in the User´s Guide and Maintenance and 

Troubleshooting Guide. In this service manual, we will NOT repeat all the information already available 

within the user's guide and maintenance and troubleshooting guide. However it is important that you also 

have these 2 guides available (take the ones from the LX series, applicable for the L65500 also).

•

Add new substrate print (User’s Guide: Handle the Substrate)

•

Printhead alignment print ( (Printhead alignment diagnostic plot & manual printhead alignment) 

(within the maintenance & troubleshooting guide, in the printer calibration chapter).

•

Advance calibration (from IPS version 4.x & FW BOB4.x)(within the maintenance & troubleshooting 

guide, in printer calibration chapter). (Go from IPS, Printer -> advance calibration,

•

Color calibration (within the maintenance & troubleshooting guide, in printer calibration chapter) 

(Go to Substrate -> color calibration).

•

Dynamic color calibration (within the maintenance & troubleshooting guide, in the printer 

calibration chapter) (Go from IPS, Printer -> color registration).

•

Printhead check (from IPS, Printer -> Printhead cleaning -> verify printhead status)

The following service prints are available from the IPS: Printer -> printhead alignment -> Verify 

alignment.

•

Media Expansion plot

•

Pen to Pen Alignment along the scan axis (scan axis encoder strip)

•

Bidirectional alignment along the scan axis + PRS diagnostics

•

Printhead check (from IPS, Printer -> Printhead cleaning -> verify printhead status)

•

Advance calibration (from IPS, Printer -> advance calibration, available from IPS version 4.0.1)

•

Dynamic Color registration (from IPS, Printer -> color registration).

•

Color calibration (from substrate -> color calibration)

Main generic steps to follow to ensure the best image quality:

•

Check the printhead alignment (from IPS: Printer -> printhead alignment -> Verify alignment)

•

Calibrate the media advance (from IPS -> Printer -> advance calibration, available from IPS version 

4.0.1), select the print mode that you plan to use.

•

Dynamic Color registration (from IPS, Printer -> color registration).

•

And to check / fine-tune the different settings, mainly the dynamic color registration, print the 

following test files from the IPS, situated under C:\user\<login>\Documents\HP IPS (from version 

4.0.1, it is available in Substrate Creation), file name: Test1_temp_profile.
Print this test file to reach a total of 1 meter length, covering all the substrate, how: 'step & repeat' 

+ fit to substrate + center and increase the number to reach a total of 1 meter length. Use the print 

more that you usually use.

•

While printing, you can fine-tune the setting through the button 'Print Adjustment':
•

The advance can be compensated through the Advance key. Need to have at least 10-20cms 

of plots printed. To know to increase/decrease:
