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.

Printhead alignment diagnostic print
Description
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.
Print access
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
