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.

[ 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.

[ 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)
F-14-42
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.
