Troubleshooting

•

The most probable cause of a printhead alignment failure is some problem with substrate advance. 

Please test substrate advance. After fixing any substrate advance issue, retry automatic printhead 

alignment.

•

Another possible cause of failure is the use of highly-textured (some banners), non-white or very 

reflective (some satin offset) substrates. Use manual printhead alignment in these cases.

•

If the substrate suffers from wrinkles during printhead alignment (automatic or manual), results will 

not be good. Try solving the problem by adjusting substrate parameters such as tension or heating 

and curing temperatures.

•

If none of the above cases apply, please try using manual printhead alignment, or call HP Support.

The printer offers a printhead alignment diagnostic plot, to assess the quality of the current printhead 

alignment. This section contains more information than is shown in the Maintenanace and Troubleshooting 

Guide.

There are two methods to access this print and there is also one variation on the print.

•

To print it, start the HP Internal Print Server and select Printer > Printhead alignment > 

Diagnostics plot.

•

You can also access the printhead alignment diagnostic print from the service menu. Service 

Menu > Service Prints > Printhead Alignment > 40ips 600x1200.

•

A 35 IPS variation on the print also exists that is printed at 1200x1200, meaning that the plot is 

compressed to half the width. Service Menu > Service Prints > Printhead Alignment > 

35ips 600x1200.
