8.12 Registration

The image is out of place between the leading and trailing edges of

the sheet. Registration problems are caused by a malfunctioning

paper feed process or by a malfunction or maladjustment on the DC

control board.

The REGVR potentiometer, on the DC control board, provides

approximately 1 cm (0.93 in) of registration adjustment. There are

no side-to-side image positioning adjustments.

1. Inspect the cassette or front tray for overloading or mechanical

damage.

2. Make sure a correct type and size paper is being used. See

Digital Laser Printers Guide to Paper and Other Media for paper

speciﬁcations.

3. Inspect the pickup and oblique rollers for damage, wear, or

surface contamination.

4. Make sure the registration sensor lever works without sticking

or binding. If the sensor lever fails to work, replace the paper

feed unit.

5. Adjusting the REGVR potentiometer to correct for a

malfunctioning component is not recommended. Find and

replace the malfunctioning part. See Section 4.9 for the

registration adjustment.

6. Swap the following parts:

a. Cassette or front pick up roller
