A counter electromotive force flows through the clutch drive circuits and causes the offtiming of the clutch to be delayed. This can result in a paper jam.
A zener diode has been added to the drive circuits of the PFB board for the following
clutches, preventing any counter electromotive force from flowing through the circuits:
1. Relay Clutch
2. Upper Paper Feed Clutch
3. Lower Paper Feed Clutch
4. By-pass Tray Feed Clutch
The new part number for the PFB board is as follows:
The A2324100 thermofuse has been discontinued by the manufacturer and has been
changed over to A2314100. With this change, the P/N for the Fusing Unit Assembly has
also been changed as shown below.

Reason for
Modification:
The parts listed below have been modified to facilitate assembly at the factory (interchangeability
0/0). However their part numbers remain the same.
Note that the SPC part number for the development unit has been changed, since the suffix for the
old part had already reached Z.
1. Sponge (AA153053, P45, #28): The material of the double-sided tape has been changed to
facilitate attachment, as the previous type tended to stretch and not stick well.
2. Decal (A2323066, P45, #31): The decal’s thickness has been reduced from 0.1 to 0.065 mm to
prevent it from partially peeling off, as it tended to do since it was attached to a curved surface.
