Example of Regular Marking
Markings may disappear by themselves. Try copying at multiple
pages to clear this problem. Markings may occur if the machine has
not been used for a long time. A possible cause is that the surface of
the drum is marked or damaged by excessive exposure to light. In
this case, replace the drum unit with a new one.
Printed pages are blurred at
the centre or at either edge.
Blurred Page
Certain environmental conditions such as humidity, high
temperatures, etc. may cause this condition to occur. Make sure the
machine is placed on a flat, horizontal surface. Remove the drum
unit with the toner cartridge installed. Try rocking them from side
to side. You may clear a blurred page by wiping the scanner window
with a clean soft cloth. (See
, page 120 and
, page 122.) If a blurred page occurs after
cleaning and the display shows
CHANGE DRUM SOON

the drum unit with a new one.
