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 in order to print with good print quality. The problem may have various causes:
The paper used was not valid, repeat the alignment with valid paper.
Printhead health problems, clean printheads, see Clean the printheads on page 157.
The alignment was done with the window open, repeat the alignment with the window closed.
If the problem persists after using valid paper, cleaning the printheads and keeping the window closed, there
may be a failure in the scanning system needing repair; 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 nd 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 Front panel recommends reseating or replacing a printhead on page 156. If that fails,
replace the printhead with a new printhead, see Remove a printhead on page 113 and Insert a printhead
on page 115.
Replace: the printhead is failing. Replace the printhead with a working printhead, see Remove a printhead
on page 113 and Insert a printhead on page 115.
Replacement incomplete: a printhead replacement process has not completed successfully, re-launch the
replacement process and let it nish completely (it is not needed to change the printheads).
Remove: the printhead is not a suitable type for use in printing.
