3.5 Troubleshooting Based on Your Printout

This section describes conceivable print quality problems that may occur with
this printer and the troubleshooting points for those errors.

Dot missing

Uneven printing/poor resolution
Smudged or marred printout on front side
Smudged or marred printout on reverse side
White/black banding
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.
1. If there is no output at all or only some the colors print, perform a
Cleaning operation (as described in Chapter 5 or as described in the
user's guide or printer software.)
2. Perform ink charging again
Enter the Self Diagnostic mode (as described in Chapter 5) and select the
Initial Fill from the cleaning menu. This forces ink through the printheads
to clear clogged nozzles.
