SUGGESTIONS
Print Quality Difficulties (
Wipe the electric terminals referring to page 20-17.
Also, do not use heat-sensitive paper as it will
cause this problem. After cleaning, if the printed
pages are still black and the LCD shows
DRUM SOON, replace the drum unit with a new
one.
Make sure that the toner cartridge is not empty.
Wipe the electric terminals. (See
Maintenance,
20-17 and
Make sure that a torn piece of paper does not
remain on the scanner window.
Marks may disappear by themselves. Try copying
multiple pages to clear this problem. Marks may
occur if the FAX/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 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.
Certain environmental conditions such as humidity,
high temperatures, etc. may cause this condition to
occur. Make sure the FAX/MFC 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 windows with a clean soft cloth. (See
Routine Maintenance,
page 20-17 and
Printer,
page 20-18.) If a blurred page occurs after cleaning
and the LCD shows
replace the drum unit with a new one.
Adjust the print conditions by setting the Print
Density function, page 5-4. Make sure you use
paper that meets the specifications. Rough surfaces
or thick media can cause a ghost image.
