Copying problems
Loose toner
• Clean the inside of the machine. See page
63.
• Check the paper type and quality. See page
33.
• Remove the toner cartridge and install a
new one. See page 66.
• If the problem persists, the machine may
require repair. Contact a service
representative.
Character Voids
Character voids are white areas within parts of
characters that should be solid black:
• If you are using transparencies, try another
type of transparency. Because of the
composition of transparencies, some
character voids are normal.
• You may be printing on the wrong surface
of the paper. Remove the paper and turn it
around.
• The paper may not meet paper
specifications. See page 33.
Horizontal stripes
If horizontally aligned black streaks or smears
appear:
• The toner cartridge may be installed
improperly. Remove the cartridge and
reinsert it.
• The toner cartridge may be defective.
Remove the toner cartridge and install a
new one. See page 66.
• If the problem persists, the machine may
require repair. Contact a service
representative.
Curl
If the printed paper is curled or paper does not
feed into the machine:
• Turn over the stack of paper in the tray.
Also try rotating the paper 180° in the tray.
• Change the printer option and try again. Go
to printer properties, click Paper tab, and
set type to Thin Paper. Refer to the
Software section for details.
An unknown image
repetitively appears
on a next few
sheets or loose
toner, light print, or
contamination
occurs.
Your printer is probably being used at an
altitude of 1,000 m (3,281 ft) or above.
The high altitude may affect the print quality
such as loose toner or light imaging. You can
set this option through Printer Settings Utility
or Printer tab in printer driver’s properties. See
page 28.

Smears, lines,
marks, or spots
appears on copies.
• If defects are on the original, press
Darkness to lighten the background of your
copies.
• If no defects are on the original, clean the
scan unit. See page 65.
Copy image is
skewed. • Ensure that the original is face down on the
scanner glass or face up in the DADF (or
ADF).
• Check that the copy paper is loaded
correctly.
Blank copies print
out. Ensure that the original is face down on the
scanner glass or face up in the DADF (or
ADF).
Image rubs off the
copy easily. • Replace the paper in the tray with paper
from a new package.
• In high humidity areas, do not leave paper
in the machine for extended periods of
time.
Frequent copy paper
jams occur. • Fan the stack of paper, then turn it over in
the tray. Replace the paper in the tray with
a fresh supply. Check/adjust the paper
guides, if necessary.
• Ensure that the paper is the proper paper
weight. 75 g/m2 (20 lb bond) paper is
recommended.
• Check for copy paper or pieces of copy
paper remaining in the machine after a
paper jam has been cleared.
Toner cartridge
produces fewer
copies than expected
before running out of
toner.
• Your originals may contain pictures, solids,
or heavy lines. For example, your originals
may be forms, newsletters, books, or other
documents that use more toner.
• The machine may be turned on and off
frequently.
• The scanner lid may be left open while
copies are being made.
