Print Quality Troubleshooting Actions
For some Print Quality problems, a Call Agent can try and troubleshoot the
Printer by requesting the Customer to perform certain actions. Using this
process, most problems can resolved without the need of an on-site visit.
Use the Print Quality Troubleshooting Wizard to help customers with their
print quality or color problems. For information about how to use the Print
Quality Troubleshooting Wizard, see
Print Quality Troubleshooting Wizard
on page 1-34.
When faced with a Print Quality problem, perform the following actions in
order to resolve the problem:
1 Printer Configuration:
 Check that the paper type loaded corresponds to the paper type selected
in the front panel and in the software. You can verify the paper type
selected through the Front Panel (Main Menu/Paper menu/View loaded
paper).
 Make sure that the correct Print Quality settings are used for different
types of print content. See
Print Quality Troubleshooting Actions on page
1-9 for further information.
 Dry time should be set to “Optimal”.
2 Perform Printhead recovery (Main Menu/Image Quality Maintenance/
Clean Printheads).
3 Media:
 Select the correct media type through the front panel when loading it.
 Make sure that HP or HP-approved media is being used.
4 Perform the Printhead Alignment (Main Menu/Image Quality Maintenance/
Align Printheads), using the same paper type with which you were
experiencing unacceptable image quality, if feasible (some paper types are
not suitable for Printhead Alignment).
5 Check if the latest version of the firmware is installed. If not, install the latest
firmware revision.
