TROUBLESHOOTING Overview 87
3.1.6.8 Dot Missing 3
This section describes the procedures for checking the following factors which can
cause instability in printing even though all nozzles are firing ink normally. Carry out
the steps in the order given.
1. Characters are not sharply defined.
2. Horizontal and vertical lines are not straight.
3. White stripes or colored stripes are easily visible after high-speed printing.
6 Let the printer stand
for a day (if time
permits). After leaving the printer for a day, (In worst case, 3 to 4
days are required.) check if the missing printing appears to
be returning to normal. If it does appear to be returning to
normal, use the cleaning function on the panel, and the CL3
cleaning function and initial ink charge flag reset function
of the adjustment program and check the progress. If it does
not appear to be returning to normal, proceed to step 7.
7 Replace the printhead.
