Cleaning
Periodic cleaning of the printer is recommended. The frequency of cleaning is dependent
upon the environment in which the printer is used. You should clean the printer:
• At least once a month.
•When the printer experiences frequent media jams.
•When print quality has deteriorated.
■External

Clearing a Jam
■Clearing a media jam
If the printer has frequent media jams, make sure that you follow these guidelines:
• Always use high-quality plain paper and transparencies. Refer to pages 111 and later.
• Make sure that you load specialty media only in the multi-purpose tray and that you
set the media thickness switch to the correct setting for the media used.
If a media jam occurs, the printer panel reports “Paper Jam.” It is followed by one of the
letters A through E that correspond to the various sensors throughout the paper path.
The following illustration shows the locations of the sensors that report media jams
(A through E).

Troubleshooting
Trouble Possible Cause Corrective Action
A single colour is not
uniform or many vertical
streaks (both light and
dark) of slightly differ-
ent density and non-
uniform colour.
The toner is almost depleted. Replace the colour toner
developer.
Half tone area has areas
of weak colour. Paper doesn’t match the environmental conditions, or
it has too much moisture.
Try fresh paper, or another
type of paper.
Store media in the original,
dust-free package in the
same environmental condi-
tions as the printer.
A single colour appears
faded. The colour density is set incorrectly in the printer
panel.
Check the density setting by
printing the Colour Calibra-
tion Page in the Colour
Calibration menu from the
printer panel. Compare the
settings with the colour
density samples on the Colour
Calibration Reference and, if
necessary, adjust the density
from the printer panel. Refer
to Setting the Colour Density
on page 31.
The toner is almost depleted. Replace the colour toner
developer soon (depending on
the complexity of your prints,
you can continue to print up
to 100 more pages).

vertical streak.
Trouble Possible Cause Corrective Action
The toner developer is almost
depleted and is not properly
applying toner.
Replace the colour toner
developer.
Small white spots
appear on OHP trans-
parency.
OHP transparency has dust
on its surface. Remove dust or stain from OHP transparency.
A single colour shows a

tal line.
The roller in the toner
developer has a slight
impression after a long
period of storage.
Run 20-30 prints. The
impression will disappear
with continued time and use.
Prints are missing fine-
line detail. The imaging unit has reached its useful life. Replace the imaging unit.
Dark colour spots and
