SUGGESTIONS
Clean the DCP's interior and the primary corona wire of the
drum unit. (See page 14-16.) Also, do not use heat sensitive
paper as it will cause this problem. After cleaning, if the
printed pages are still black or the LCD shows
DRUM SOON, replace the drum unit with a new one. The
drum unit may be damaged.
Make sure that the toner cartridge is not empty. Wipe electric
terminals referring to Routine Maintenance and Cleaning the
Drum Unit, on pages 14-14 and 14-16. 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 DCP
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
exposure to light. In this case, replace the drum unit with a
new one.
Certain environmental conditions such as humidity and high
temperatures may cause this condition to occur. Make sure the
DCP 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 and Cleaning the Drum Unit, on pages 14-14
and 14-16.) If a blurred page occurs after cleaning and the
LCD shows CHANGE DRUM
with a new one.
Adjust the print conditions by changing the Print Density
setting, page 4-2—OR—
Rough surfaces or thick media can cause a ghost image. Make
sure you select the Paper Type that suits the paper in your
multi-purpose sheet feeder. (See Paper Type, page 5-6 and
Media Type, page 8-4.)
