Remedy
The copy is dirty. Is the document glass or the 
document cover dirty?
Clean the document glass and the 
document cover.
Refer to "Cleaning the Document Cover and 
Document Glass" (P.94).
Is the document a 
transparent type such as a 
transparency film?
If the document is transparent, dirt on the 
document cover will be copied. Place a

rough, or a blueprint?
Adjust the copy density or image quality.
Refer to "3 Copy" > "Image Quality" in the

Glossy printing paper easily sticks to the 
document glass, and shadows are 
sometimes copied, soiling the image. 
Place a transparency film under the 
document when copying.
The copy has 
black lines.

transport glass for the
