Color is Uneven or Color is Wrong

Step Question and Actions
1 Remove discolored jets in the printhead jets by printing the solid fill test print in the
color with the discolored jets. For instructions on printing solid fill test prints, see
"13-19: Black, Red, Green, Blue, Cyan, Magenta, and Yellow Solid Fills" on
page 5-31.
2 Clean the maintenance kit wiper blade.
3 Purge the printhead up to three times. If some improvement is seen, the ink could be
discolored due to a long period of time without use. Print the solid fill test print for the
problem color until the problem resolves. See"13-19: Black, Red, Green, Blue, Cyan,
Magenta, and Yellow Solid Fills" on page 5-31.
4 Check the thermal regulation of the Drum using diagnostics check test. For
information about diagnostics, see "Service Diagnostics Mode Menu" on page 5.

This may be due to incorrect colors in the
ink loader, old ink in the printhead, color
mixing at the faceplate, or drum thermal
problems.
Note
Using non-Xerox ink may cause
unpredictable color results.
