Print Quality Service Check
FRU / Function Action
1 Print Cartridge Be sure the machine contains good print
cartridges.
2 Color Print
Cartridge Cross
Contamination Cross contamination of color inks results in
incorrect colors printed, as when green prints for
yellow, (when yellow and blue are mixed in the
print cartridge). This problem resolves quickly as
the print cartridge is used.
If cross contamination occurs, check the following:
• The maintenance station wiper for damage.
• The printhead nozzle plate was resealed with
tape.
3 Printhead Carrier
Assembly Reseat the printhead cables in the system board
and check the following parts for wear or damage:
• Print Cartridge Latch
• Latch Spring
• Carrier
4 System Board
Printhead Cable
Rubber Backer Run the “Test Page” on page 3-1. A void in the
print indicates one or more print nozzles are not
working. Run the test again to verify the failure. Be
sure the printhead cables are connected properly.
Remove the print cartridges and check the gold-
plated contacts on the end of the printhead carrier
cable for dirt, wear and damage. Use only a clean
dry cloth to clean the contacts.
A worn rubber backer results in poor contact
between the printhead carrier cable and the print
cartridge. Check the rubber backer for wear.
If the symptom remains, replace the system board.
5 Maintenance
Station Intermittent nozzle failures can be caused by worn
parts in the maintenance station. Perform the
“Maintenance Station Service Check” on
page 2-7
, then return to this check.
