Symptoms Possible Cause Remedy
Copies are dirty. The document glass
cover or document glass
is dirty. Clean the document glass cover or document
glass.
Refer to
Cleaning the Document Glass Cover
and the Document Glass on page 248.
The document is a
transparency or highly
translucent medium. When copying highly translucent documents,
dirt on the document glass cover shows up in
the copy. Place a sheet of white paper over the
document before copying.
The document is on
colored or rough paper, or
is a blueprint. The paper's background color is being copied.
Adjust the copy density or image quality, or
specify background suppression before
copying.
The document is printed
on glossy printing paper. Glossy printing paper easily sticks to the
document glass, and shadows can resemble
dirt in the copy. Place a transparency or
transparent film under the document before
copying.
Copies are too dark or
too light. The copy density
adjustment is not right. Adjust the copy density.
Refer to
Lighten/Darken on page 84.
The document is light. Adjust the copy density.
Refer to
Lighten/Darken on page 84.
The image quality setting
is not correct for the
document. If the copy output of black text is too light, set
[Original Type] to [Text].
Refer to
Original Type on page 85.
The copy is slightly out
of position. The paper loaded in the
tray is misaligned. Align the paper stack, and load it so that the
leading edge of the paper is aligned with the
front corners of the tray.
Copies have missing
parts in them. The paper is damp. Damp paper creates missing parts or unclear
copies. Replace it with paper from an
unopened pack.
The paper in the tray is
creased or wrinkled. Remove any problematic sheets, or replace the
paper with paper from an unopened pack.
The document has been
cut-and-pasted, or is
creased. Cut-and-pasted or creased parts of the
document may not be making proper contact
with the document glass. Place a stack of
white paper on top of the document to bring it
into proper contact with the document glass.
