corrective action
If this error code appears again, check
the Printhead Alignment print:
– If the Printhead Alignment was printed
correctly without any print defects, then check that the media
is moving freely (backwards and forwards) while the printer
is scanning it.
– If the Printhead Alignment was printed
incorrectly, with some print defects, replace the faulty Printhead
of the color where the defects were noticeable.
