Remedy
Clean the document glass or the document
cover.
Refer to "Cleaning the Document Cover
and Document Glass" on page 11-15.
If the document is highly transparent,
marks on the document cover will be
copied. Place a white sheet of paper on the
document and make a copy.
Either adjust the copy density or image
quality and then retry copying.
Refer to "Image Quality" on page 3-26,
"Lighten/Darken (Adjusting the Copy
Density)" on page 3-27.
Glossy printing paper sticks easily to the
document glass and shadows are
sometimes copied and reproduced as dirt.
Place a transparency or highly transparent
film under the document and retry copying.
Clean the document glass.
Refer to "Cleaning the Document Cover
and Document Glass" on page 11-15.
Adjust the copy density.
Refer to "Lighten/Darken (Adjusting the
Copy Density)" on page 3-27.
Align the edges of the paper and load the
paper again so that is flush against the
paper tray corners.
Refer to "Loading Paper" on page 8-4.
