Solution 4: Clean the glass

Solution: Clean the glass and lid backing.
For more information, see:

•

“Clean the lid backing” on page 60

•

“Clean the glass” on page 59

Cause: Debris might be stuck on the glass or on the back of the document lid; this
causes poor copy quality and slows down processing.

If this did not solve the issue, try the next solution.

Solution 5: Clean the print cartridges

Solution: Check the estimated ink levels remaining in the print cartridges.

NOTE:

Ink level warnings and indicators provide estimates for planning

purposes only. When you receive a low-ink warning message, consider having a
replacement cartridge available to avoid possible printing delays. You do not need
to replace the print cartridges until print quality becomes unacceptable.

If there is ink remaining in the print cartridges, but you are still noticing a problem,
print a self-test report to determine if there is a problem with the print cartridges. If the
self-test report shows a problem, clean the print cartridges. If the problem persists,
you might need to replace the print cartridges.

For more information, see:

•

“Print cartridge troubleshooting” on page 88

•

“Print a self-test report” on page 61

Cause: The print cartridges needed to be cleaned or there was insufficient ink.

NOTE:
