Check for missing dots and incorrect print.
A pattern such as the figure shown on
the right is printed.
Check that no line is missing and that
the ink ejection direction is straight.
Perform a normal cleaning (PH
RECOVERY) if a line is missing or the ink
ejection direction is not straight.
If the same problems still appear after
performing normal cleaning several
times, configure nozzle map with the
procedure below.
Missing lines are found
No line is missing and the
printout is correct
Ink is not ejected straight
Ink is ejected straight
and the printout is correct
If the spaces between
the lines are even, the
ink is ejected straight.
If there are uneven
spaces between lines,
the ink may not be
ejected straight.
Example when the nozzle 159
does not eject ink straight.
Mark for the last nozzle (nozzle 508)
Check that nozzle print is complete up
to the right of this mark.
Example when lines for nozzles 24 and
133 are missing in the printout.
