4.4.3 PAPER FEED SKEW
SYMPTOM:
Paper feed skew sometimes occurs (Printer and Copier).
CAUSE:
The registration roller bushing on rear side is damaged by some reason. One of the
reasons of damaging the bushing is that the tip of the rear registration pressure
spring is facing the wrong way. As a result, the spring touches the bushing when
the registration roller rotates, and damages the bushing.
NOTE: For the location of this bushing, see callout #25 on pg. 100 of the Parts
Catalog (“43. Transfer Entrance 2")
SOLUTION:
• Check the rear bushing of the registration roller.
• If the bushing is damaged, replace it with a new one.
• Check the position of the rear registration pressure spring (see procedure
below).
• If the spring is in the “NG position”, change the spring to the “OK” position.
NOTE: For the location of this spring, see callout #22 on pg. 100 of the Parts
Catalog.
