Recommendation
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 the problem by wiping the scanner windows
with a clean soft cloth. (See "Regular Maintenance" and
"Cleaning the Drum Unit" on page 13-1~3.)
If the same problem occurs after cleaning and the display
shows CHANGE DRUM, replace the drum unit with a new
one.
• Turn the print density dial counterclockwise for lighter
images. See "The Print is too Light or too Dark" on page 13-
12.
• Make sure that you use paper that meets the spacifications.
Rough surface or thick media can cause the problem.
I NOTE
The drum unit is a consumable item, and it is necessary to replace it periodically.
