Symptom Remedy
The copy is smudged. Clean the document glass or the document cover if it is soiled.
Refer to "Cleaning Document Cover and Document Glass" (P.403).
If the original is transparent, smudge on the document cover will be
copied. Place a white sheet of paper on top of the original when
copying.
If the original is colored paper, rough paper, or blueprint, the
background color may be copied.
Adjust the copy density or image quality.
Refer to "Features List" (P.130).
Glossy printing paper easily sticks to the document glass, and
shadows are sometimes copied, soiling the image. Place a
transparency film under the original when copying.
The copy has black lines. Clean the constant velocity transport glass.
Refer to "Cleaning White Chute and Constant Velocity Transport Glass" (P.403).
