If this did not solve the issue, try the next solution.
Solution 3: Replace the print cartridges
Solution: Replace the print cartridges that are experiencing the problem. If only one

using ink-backup mode.
NOTE: During ink-backup mode, the product can only print jobs from the
computer. You cannot initiate a print job from the control panel (such as copying
or scanning an original). For more information, see
“Printing in ink-backup
mode” on page 87 .
Cause: One or both of the print cartridges were having a problem.
