Retrofit Information
The quantity of the separation belt have been changed from two to four.
Reason of the modification:
On the original printed by the laser printer, the toner may not be fused sufficiently and the
image may smeared by the separation belts.
To prevent this, two more separation belts are added to widen the contacting area
between the separation belts and the original so that the separation pressure is not
concentrated to the narrow area.
After this modification, these separation belts are still PM parts and the replacement
interval is 1PM (120k copies) as same as before this modification.
Because of this modification, the illustrations in page 7, 14, 15, 34 and 35 should be
changed. The quantity of the separation belts should be doubled. There is no correction
except illustrations.
