Print Quality Problems

Problem
Print quality is not what
you expect; print is not
clear; splashed or missing
dots, white streaks
10-14 Troubleshooting
Cause
Another Windows application
on your computer may be
trying to communicate with
the printer port the MultiPASS
Server is using. This conflict
can result in strange printing
behavior.
Make sure the MultiPASS
Server is loaded.
Your pages may include a
large amount of ink.
A device time-out occurs when
the computer sends data to the
MultiPASS, but the MultiPASS
does not respond. The
MultiPASS may be unplugged,
not connected to the computer,
or have a paper jam.
Cause
The paper you are using
may not be supported by
the unit.
You may be printing on the
wrong side of the paper.
The print head nozzles
may be clogged.
Solution
Uninstall or remove the
software application.
If the MultiPASS Server icon
does not appear on the bottom
of your screen, turn on the
MultiPASS Server.
Remove each sheet as it is
printed. Allow it to dry, then
roll it in the opposite direction
of the curl.
Make sure the MultiPASS is
plugged in, and that its
interface cable is securely
attached to the unit and to
the computer. Clear any paper
jams, and make sure paper is
loaded properly in the sheet
feeder.
Solution
Make sure you are using
the recommended paper
(see page A-2).
Some paper has a right side
for printing. If the print quality
is not as clear as you would like
it to be, try turning the paper
over and printing on the other
side.
Clean the print head (see
page 9-8); repeat cleaning
if necessary. If print quality is
not recovered after executing
the cleaning five times, replace
the BJ cartridge.
