1801 Motor Speed Adjustment DFU
These SP’s adjust the speeds of the feed motor (paper cassette), main motor,
and fusing motor. The motor speeds can be adjusted to correct images that
appear scratchy or of uneven density. This can occur when:
! Copying originals with large quantities of black.
! Copying originals with a large quantity of black near the trailing edge.
! Printing multiple copies of positive/negative (reverse) images.

Roll DFU
[-30 to +30/0/1]
For every change of “1”, speed is adjusted 1/1635 or approximately 0.06%
Std: (70 MHz/32)/1635 = 1338 pps
Example : If the setting is changed by “+10” then:
(70 MHz/32)/(1635-10) =
(70 MHz/32)/(1625) = 1346 pps
