Ghost Images
The drum unit is a consumable and it is necessary to replace it periodically.
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 Regular Maintenance, page 138) 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 changing the Print Density setting.
(See Setting the Print Density, page 28)—OR—Rough surfaces or
thick media can cause a ghost image. Make sure you select the Paper
Type that suits the paper in your paper type. (See Paper Type, page
57 and 58 and Media Type, page 68)
