Copying problems
When a fax is received,
the size of the printed
document image does not
match the size of the
paper. • Make sure that the paper size setting is correct (see
page 22).
• Make sure that an appropriate reception ratio setting
has been selected (see page 96).
No reception occurs when
polling is attempted. • Make sure the transmitting machine is in automatic
reception mode.
• If the transmitting machine has polling security, make
sure that your fax number has been entered both in
your machine (see page 41) and in the transmitting
machine.
Problem Solution
The quality of copies is
poor and/or dark vertical
lines appear when the
document feeder is used. • 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 131.
The paper comes out
blank when you make a
copy. • 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.
The size of the printed
document image does not
match the size of the
paper. • Make sure that the paper size setting is correct (see
page 22).
• Make sure an appropriate enlarge/reduce setting is
selected (see page 54).
Dots appear at regular
intervals on copies. • The drum cartridge may be damaged. Replace the
drum cartridge.
A copy is faint. • Adjust the contrast setting (see page 55).
• If output is generally faint, the toner cartridge may
need replacement.
