HP (Hewlett-Packard) T1200 User Manual

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 

●

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 reparation or the printheads, although
clean, may not work and need to be replaced.

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 

. If that fails, replace the printhead with a new printhead, see 

 and 

●

Replace: the printhead is failing. Replace the printhead with a working printhead, see 

 and 

●

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.
