Copying problems

Problem
The quality of copies is
poor and/or dark vertical
lines appear when the
document feeder is used.
The paper comes out
blank when you make a
copy.
The size of the printed
document image does not
match the size of the
paper.
Dots appear at regular
intervals on copies.
A copy is faint.
• Any dirt or material on the scanning glasses will
cause spots or lines to appear on copies (and on
transmitted faxes and scanned images). Clean the
scanning glasses as explained on page 133.
• If you are using the document feeder, make sure the
original is placed face up in the feeder.
• If you are using the document glass, make sure the
original is placed face down on the glass.
• Make sure an appropriate enlarge/reduce setting is
selected (see page 56).
• The drum cartridge may be damaged. Replace the
drum cartridge.
• Adjust the contrast setting (see page 57).
• If output is generally faint, the toner cartridge may
need replacement.
