When a machine with earlier than the following serial numbers causes a symptom like the above, replace the vertical roller bushing and compression spring

of the feed roller with new ones at the same time.

14.3.5.2 011B Jam Code occurs at delivery assembly only when using small size paper (smaller than A4/LTR): Backside

Driver PCB is faulty

[ Inspected by Canon Inc. ]

Description

Since "001B" Jam occurred at the delivery assembly only when using a small size paper (smaller than A4/LTR), the backside driver PCB was replaced with

a new one for solution.

- 011B Jam Code can be displayed when a delay jam occurred at the decurler inlet sensor.

Cause

Since the backside driver PCB was faulty, the delivery roller failed to rotate when printing a small size paper, causing 011B jam.

Field Remedy

1. Re-fit J3806/J3811 connector of the backside driver PCB.

2. Re-fit J4025/J4204 connector of the decurler PCB.

3. If the symptom still occurs, replace the backside driver PCB with a new one.

14.3.5.3 021B Jam Code/abnormal noise/open lever is hard to shift: Longer screw is used to fix decurler

[ Inspected by Canon Inc. ]

Description

Since a 15mm-long screw [3] was used to mount the decurler unit instead of a 8mm-long binding screw (M4 x 8) [2], the tip of the screw contacted to the

pressure plate and prevented the swing movement of the plate. This caused a paper jam or abnormal noise at the inlet of decurler. In an inspection case, the

open lever [5] was hard to shift because the pressure plate was mounted in the wrong position when screwing the decurler unit.

- 021B: Stationary jam at the decurler inlet sensor (PS76)

In case the screw is contacting to the pressure plate, it is confirmed that the decurler roller [6] is lifted to a position higher than the regular position [7] (see

Photo [8]) when the open lever is shifted.
