Suggestions
If toner scattered over the whole printing surface, adjust the
print density dial inside the printer counterclockwise. See “The
Print is too Light or too Dark”on page 186.
Clean the MFC’s interior. See “Regular Maintenance” and
“Cleaning the Drum Unit” on page 165-167.
Make sure that you use paper that meets specifications. See
page 130.
If you still have scattered toner and the display shows CHANGE
DRUM SOON, replace the drum unit with a new one.
Wipe the electric terminals referring to page 166. Also, do not
use heat-sensitive paper as it will cause this problem.
After cleaning, if the printed pages are still black and the display
shows CHANGE DRUM SOON, replace the drum unit with a
new one.
• Make sure that the toner cartridge is not empty.
• Wipe the electric terminals referring to “Regular Maintenance”
and “Cleaning the Drum Unit” on pages 165-167.
• Make sure that a torn piece of paper does not remain on the
scanner window.
Markings may disappear by themselves. Try copying multiple
pages to clear this problem. Markings may occur if the MFC 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 markings do not disappear, it may be that the drum was
marked or damaged by excessive exposuj*e to light. In this case,
replace the drum unit with a new one.
