General Troubleshooting
Some parts of the image are lost
during 2-up copying.
When printing
envelopes, the scale
was specified and
then 2-up copying
was set.
With 2-up copying,
the scale is
automatically
adjusted. For 2-up
copying on media
with a narrow printing
area, set 2-up copying
and then adjust the
scale if necessary.
The printer resets or turns off
frequently.
The power cord is not
correctly plugged
into the outlet.
Turn off the printer,
confirm that the
power cord is correctly
plugged into the
outlet, then turn on
the printer.
The printer is making unusual
noises.
The printer is not
level.
Place the printer on a
flat, hard, level
surface.
The paper tray is not
installed correctly.
Remove the tray that
you are printing from
and reinsert it
completely into the
printer.
There is a foreign
object stuck inside
the printer.
Turn off the printer
and remove the
object.
The Fuser or Duplex
Unit are not installed
incorrectly.
Remove each unit and
reinstall correctly.
With 2-up on multiple copies, the
output is incorrect.
Both the printer
driver and the
application have
been set for collation.
For 2-up copying on
multiple copies,
choose Collate only in
the printer driver’s
Basic tab. Do not set
collation in the
application.
Booklet Left and Right Binding
output is incorrect.
Both the printer
driver and the
application have
been set for collation.
For Booklet Left
Binding and Booklet
Right Binding, choose
Collate only in the
printer driver’s Basic
tab. Do not set
collation in the
application.
