MAINTENANCE
Printed pages are blurred at
the centre or at either edge.
Blurred Page
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 139.) 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.
Ghost Images
Adjust the print conditions by setting the Print Density function.
(See Setting the Print Density, page 28.) Make sure that you use
paper that meets the specifications. (See Acceptable Paper, page
64.) Rough surfaces or thick media can cause a ghost image.
The drum unit is a consumable and it is necessary to replace it periodically.
