General Troubleshooting
When the paper type or paper
size for Tray 1 is changed, the
printer control panel displays the
message Check Fax Mode.
If a fax is received, it
could not be printed
on paper of the
currently specified
type or size. However,
you can still copy and
print.
Press the Fax button
and then check the
error details.
To print a received
fax, change the paper
type setting to Plain
Paper and the paper
size to Letter, A4, or
Legal (whichever is in
the paper tray).
Printing takes more time than
expected.
The printer is set to a
slow printing mode
(for example, Thick
Cardstock).
It takes more time to
print with special
media. When using
regular paper, make
sure that the paper
type is set properly in
the printer driver.
The printer is set to
Energy Saver mode.
It takes more time for
printing to start in
Energy Saver mode.
If an error is detected
while the print job is
being transmitted
while the printer is in
Copy mode, it takes a
while to process the
error and resume the
printing job.
Wait. No action is
needed.
Blank pages are printed.
One or more of the
toner cartridges are
defective or empty.
Inspect the toner
cartridges. The image
may not print
correctly or not at all
if the cartridges are
empty.
Not all of the pages print.
A different user
accidentally canceled
the job.
Try printing the
remaining pages.
The paper tray is
empty.
Verify that the tray is
loaded with paper.
A document is
printed with an
overlay file which has
been created by an
unsuitable printer
driver.
Print the overlay file
using a suitable
printer driver.
