3.1.4 Troubleshooting Based on Your Printout

This section describes the conceivable print quality problems that may occur
with this printer and the troubleshooting points for those errors.
Table 3-4. Print Quality Problems

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, check the ink valves on either
side of the printer I/H Assemblies to make sure the knobs are set to "Open". (Also, see
the user's guide or printer software.)
2. Perform ink charging again
Select the "Cleaning" function on the control panel's Self-Diagnostic menu. This sends
a lot of ink into the heads and forces out the old ink that is clogging the nozzles.
Do not charge ink too often as this operation
consumes a lot of ink. Each head consumes about
94.43ml per operation.
