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.
