Toner scatters and stains
the printed page.

Scattering Toner

Adjust the print conditions by setting the Print
Density setting. Remove the drum unit and clean
the machine’s interior. (See

Routine Maintenance

,

page 13-18,

Cleaning the Printer,

page 13-18 and

Cleaning the Drum Unit,

page 13-19.) Make sure

that you use paper that meets specifications. (See
pages 2-6.) If you still have scattered toner and the
LCD shows

CHANGE DRUM SOON

, replace

the drum unit with a new one.
Check the machine’s environment. Conditions
such as humidity and high temperatures may cause
this print defect to occur.

The whole page is
printed black.

Black Page

Wipe the electric terminals referring to page 13-18.
Also, do not use heat-sensitive paper because it
will cause this problem. After cleaning, if the
printed pages are still black and the LCD shows

CHANGE DRUM SOON

, replace the drum unit

with a new one.

Nothing is printed on
the page.

White page

Make sure that the toner cartridge is not empty.
Wipe the electric terminals. (See

Routine

Maintenance,

page 13-18,

Cleaning the Printer,

page

13-18 and

Cleaning the Drum Unit,

page 13-19.)

Make sure that a torn piece of paper does not
remain on the scanner window.

Printed pages are
marked at regular
intervals.

Example of Regular

Marks

Marks may disappear by themselves. Try copying
multiple pages to clear this problem. Marks may
occur if the machine has not been used for a long time.
A possible cause is that the surface of the drum is
scratched. You must then replace the drum unit with
a new one. If the marks do not disappear, it may be
that the drum was marked or damaged by excessive
exposure to light. In this case, replace the drum unit
with a new one.
