Printed pages are
blurred at the center or
at either edge.
Blurred Page
Certain environmental conditions such as humidity
and high temperatures 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
Routine Maintenance, page 13-18, Cleaning the
Printer, page 13-18 and Cleaning the Drum Unit,
page 13-19.) If a blurred page occurs after cleaning
and the LCD shows
CHANGE DRUM SOON ,
replace the drum unit with a new one.
Ghost images appear on
the printed page.
Ghost Images
Adjust the print conditions by setting the Print
Density setting, page 5-4. Make sure you use paper
that meets the specifications. Rough surfaces or
thick media can cause a ghost image.
Note
The drum unit is a consumable item and it is necessary to replace it periodically.
