6.1.10. White Spots in Black Image Areas

Possible Cause (Printer)

•

The drum surface is damaged (this is likely if the dots appear at 94.2
mm intervals).

•

The development roller surface is damaged (this is likely if the dots ap-
pear at 62.8 mm intervals).

•

The toner application roller surface is damaged (this is likely if the dots
appear at about 16.75 mm intervals).

Action:

•

Replace the drum.

•

Clean the surface of the development roller and change the roller if it is
damaged.

•

Change the development unit.
