Scanning errors during alignment
If the alignment process fails, a Scanning problems message appears on the front panel. This means
that the alignment has not completed successfully. Therefore the printer is not aligned and the alignment
should be repeated before printing with good image quality. The problem may be due to:
●
The paper used was not valid, repeat the alignment with valid paper.
●
Printhead health problems, clean printheads, see
Clean the printheads on page 187.
●
The alignment was done with the scanner raised, repeat the alignment with the scanner lowered.
If the problem persists after using valid paper, cleaning the printheads and keeping the scanner
lowered, there may be a failure in the scanning system needing reparation or the printheads, although
clean, may not work and need to be replaced.
Printhead status messages
These are the possible printhead status messages:
●
OK: the printhead is working normally, with no known problems
●
Missing: there is no printhead present, or it is not correctly installed in the printer.
●
Test printhead separately: you are recommended to test the printheads individually to find
the failing printhead. Remove all the printheads and insert them alone one by one, closing the
latch and the carriage cover after every insertion. The front-panel display indicates the failing one
showing the reseat or replace message.
●
Reseat: you are recommended to remove the printhead and then reinsert it. If that fails, clean the
electrical connections, see
The front-panel display recommends reseating or replacing a printhead
on page 186. If that fails, replace the printhead with a new printhead, see Remove a printhead
on page 148 and Insert a printhead on page 152.
●
Replace: the printhead is failing. Replace the printhead with a working printhead, see
Remove a
printhead on page 148 and Insert a printhead on page 152.
●
Replacement incomplete: a printhead replacement process has not completed successfully, re-
launch the replacement process and let it finish completely (it is not needed to change the
printheads).
●
Remove: the printhead is not a suitable type for use in printing.
