SUGGESTIONS
Print Quality Difficulties (
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 and
Printer,
page 13-19.) If a blurred page occurs after cleaning
and the LCD shows
replace the drum unit with a new one.
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.
