DIFFICULTY SUGGESTIONS
Printed pages are blurred at the center Certain environmental conditions such as humidity, high temperatures,
or at either edge. 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 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.
Ghost images appear on printed page. 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. Make sure that you select the
appropriate media type in the printer driver.
