Remedy
Clean the document glass and the
document cover.
Refer to "3 Maintenance" > "Cleaning the
Machine" > "Cleaning the Document Cover

document cover will be copied. Place a
white sheet of paper on top of the
document when copying.
Adjust the copy density or image quality.
Refer to "3 Copy" > "Image Quality" in the
User Guide.
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.
Clean the narrow glass strip.
Refer to "3 Maintenance" > "Cleaning the
Machine" > "Cleaning the Narrow Glass Strip
and Document Presser" in the Administrator
Guide.
Adjust the copy density.

User Guide.
Align the paper edges, adjust them to the
tray's top corners, and reload the paper.
