Image

Description
When printing images of uniform density with a large amount of toner deposit, uneven gloss
(uneven density) of paddle pattern may appear on the images.
It tends to occur especially with heavy paper/heavy coated paper.

Cause
In printing images with a large amount of toner deposit (e.g. solid image), the amount of wax
precipitated at the images after fixing increases.
Images with a large amount of toner deposit tend to be glossy. The difference in gloss on the
images tends to be obvious according to the difference in times of cooling and solidification of
wax components that have been melted after fixing.

Field Remedy
Decrease the control temperature of the primary fixing in user mode.
