Sometimes when the paper exit tray lowers an abnormal noise can occur. To prevent the
noise, the grease in the torque limiter has been changed. See the diagram below to
distinguish the new torque limiter from the old one.

9. CB10 Feed Motor Abnormality
When this error occurs check the following items:
One-way bearing located inside the cam shutter (part number 4402350530 CAM-
SHUTTER). This may slip causing the error code. Clean/replace as needed.
Safety Switch (MS3) – The spring may not push hard enough on the actuator; reform
the switch arm to make good contact.
10. Intermittent Stapling
Perform Alignment Position adjustment (MJ1027/28 SM page 6-1). If the alignment is too
tight this may produce a buckle lifting the center of the paper off the stapling tray sensor
(PI4).
11. Mis-Stapling
Check the paddles and make sure they are not worn.
Check that the Paddle Solenoid (SL5) is working and that the paddles rotate during
every copy.
12. Adjustments that must be done when boards are replaced
When replacing boards and some sensors there are certain adjustments that must be done.
The adjustments can be found in Chapter 6 of the SM.
