SUGGESTIONS
Adjust the print conditions by setting the Print Density
function. Clean the machine's interior. See "Regular
Maintenance" and "Cleaning the Drum Unit" in this
chapter. Make sure that you use paper that meets
specifications. See chap. 13. 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. 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" in this chapter. Make sure
that a torn piece of paper does not remain on the scanner
window.
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.

Remove the drum unit with the toner cartridge installed.

blurred page by wiping the scanner windows with a clean
soft cloth. (See "Regular Maintenance" and "Cleaning the
Drum Unit" in this chapter.) If a blurred page occurs after
cleaning and the display shows CHANGE DRUM SOON,
replace the drum unit with a new one.
Adjust the print conditions by setting the Print Density
function. Make sure that you use paper that meets the
specifications. Rough surfaces or thick media can cause a
ghost image.
