3.4 Troubleshooting Based On Printout
This section describes conceivable print quality problems that may occur with this printer
and the troubleshooting points for those errors.
3.4.1 Dot Missing
When the printer is not used for a long period of time, the ink in the nozzles can dry up and
clog the nozzles. Clogged nozzles cannot fire ink and cause the dot-missing problem in
printed documents. If the printhead nozzles do not clear after attempting multiple cleaning
operations, check the following points.

3.4.2 Uneven Printing / Poor Resolution
If printout quality suffers from unevenness, poor quality, or similar problems, check the
following.
1.
Perform platen gap adjustment
Using the control-panel setting or the diagnostic-program function, check the platen
gap (bi-directional printing position as well as PG adjustment).
2.
If this error occurs only when the user prints on custom or thick paper, (Use the control
panel paper thickness setting to correct the paper size and the print position (depending
on the paper-thickness setting, the location where the ink strikes the paper may
change))
3.
With "maintenance mode 2], the correction value of "BI-D offset # 1 (speed priority)/#
2 (quality priority)" tries to be changed.
4.
In the case that this faulty occurred as soon as I exchanged the C362DRV board
