Overview
Table 3-21. Dot Missing 2
Remedy
If there is any dust or foreign matter on the edge of the cap
as shown below, then the head and the cap will not seal
together correctly and ink will not be suctioned correctly. If
dust or other foreign matter is present, use a cotton swab or
similar to clean it all off.
Furthermore, if the edge of the cap has been damaged in
some way, it will interfere with suctioning of the ink, and
air may be drawn into the head. If this has happened,
replace the whole of the cap unit.

After carrying out all checks, carry out cleaning once more
and check if the problem is solved.
Check that the mis-firing nozzle(s) gradually return to
normal. If they do appear to be returning to normal, repeat
the CL3 cleaning procedure using the adjustment program
until the nozzles are all fully clean. If they do not appear to
be returning to normal, proceed to step 5.
Check that the mis-firing nozzle(s) gradually return to
normal. If they do appear to be returning to normal,
repeatedly reset the initial ink charge flag and turn the
power on using the adjustment program until the nozzles
are all fully clean. If they do not appear to be returning to
normal, proceed to step 6.
