Copies are too light. Image density is too light. Adjust the image density set-
ting. See p.30 “Adjusting
Copy Image Density”.
Damp or rough grain paper is
used.
For good copy quality, use
recommended paper.
Note
❒ If you use coated paper
(such as thermal fax paper,
art paper, carbon paper),
damp paper, or rough
grain paper, copy image
might be too light.
Toner fusing is poor. The fusing temperature is too
low.
Adjust the fusing temperature
for the paper. See “Fusing Ad-
justment”, General Settings
Guide.
The copy paper is too thick.
A moire pattern appears on
copies.
Your original has a dot pat-
tern image or many lines.
Change the orientation of the
original. This may prevent the
moire pattern.
Copy using “Photo” or
“Sharpen Text”.
Image density is uneven. The original has areas of solid
color, or Positive/Negative is
selected when copying multi-
ple sheets.
When using Repeat Copy
with originals that have areas
of solid color, set the number
of originals as follows:
A0 – A2 (E – C): 1 sheet, A3 (B)
or smaller: 3 sheets
Halftone originals can cause
this problem.
Try using “Text/Photo” or
“Photo”.
Images are blurred when us-
ing translucent paper.
Translucent paper is being
used when copying multiple
sheets.
Adjust the fusing setting to
match the paper type. See
“Fusing Adjustment”, General
Settings Guide.
Wrinkles appear when using
translucent paper.
Fusing temperature is too low. Adjust the fusing setting to
match the paper type. See
“Fusing Adjustment”, General
Settings Guide.
The paper type has recently
been changed from plain pa-
per to translucent paper.
Wait about one minute.
The background on translu-
cent paper is dirty.
More than 50 copies are being
made of originals longer than
1189 mm (46.9") with solid
blocks of color (2 mm × 900
mm (0.08" × 35.4") or larger.)
Adjust the fusing setting to
match the paper type. See
“Fusing Adjustment”, General
Settings Guide.
