Image-Quality Troubleshooting

Analyzing Service Test Prints
A variety of test prints are available in the Hidden Service Menu to aid in determining
the quality of output from the system and to assist in troubleshooting problems. This
section shows how to select and analyze all test prints available to the system. To
access the Test Print menu, see the "Hidden Service Menu" on page 4-2.
Note
Defects revealed by the prints may not occur in the course of ordinary printing. In
servicing the system, you should minimize the defects shown by the prints but
not necessarily eliminate them.
Test Print Examples
1: Weak/Missing Jet
This print shows the jets not outputting enough
ink, if any, compared to its neighboring jets.
Note that the yellow jets’ bands have a small
amount of cyan ink added to them. This tints
them green to make them more visible.
Look for:
No interlacing is used in this print:
expect light/dark variation between jets. Use
Look for much lighter colored vertical bands in
the horizontal bars. Weak jets in the yellow
band are distinguished by a cyan tint.
Causes:
A jet may be partially clogged.
Perform printhead clean/purge cycles on the
printhead to remove contaminants from the
poorly-performing jet. Run a jet fix cycle by
downloading the snippet from the customer
support site.
If jet substitution mode is required, see "Jet
Substitution Mode" on page 6-12. Test the
purge system and the wiper blade performance.
Turn the system off for 4 to 6 hours (or
overnight, if practical). Then perform a clean/
purge cycle again. There may be a problem in
the purge pump assembly or the wiper
assembly may not be compliant. Verify that the
printer is using Xerox ink. Follow the
instructions on the “Printhead Troubleshooting
Checklist”.
