Symptom
0112/0113/0213/0208/0209 jam codes attributed to operation failure of the Reverse Detachment
Solenoid
[Inspected by Canon Inc.]
Description
Any of 0112/0113/0213/0208/0209 jam-codes indicated upon face-down delivery.
- 0112: Inner Delivery Sensor Delay Jam
- 0113: Outer Delivery Sensor Delay Jam
- 0213: Outer Delivery Sensor Stationary Jam
- 0208: Duplex Merging Sensor Delay Jam
- 0209: Duplex Outlet Sensor Delay Jam
Cause
Upon face-down delivery, the Reverse Upper Flapper Solenoid (SL5) [1] is turned OFF to let the paper
passed through the delivery assembly enter the Reverse Upper Roller [2]. Then, when the paper reaches
the reverse position, the Reverse Motor (M14) [3] is reversed to feed the paper to the Outer Delivery Roller
[4] side.
When the leading edge of the reversed paper reaches the Outer Delivery Roller [5], the Reverse
Detachment Solenoid (SL12) [6] is turned ON to disengage the Reverse Upper Driven Roller [7]. This
operation prevents jam when the trailing edge of the first sheet overlaps the leading edge of the second
sheet on the Reverse Upper Driven Roller.
The Reverse Detachment Solenoid (SL12) [6] was not turned ON even when paper reached the Outer
Delivery Roller, which caused the Reverse Upper Driven Roller [7] not to disengage resulting in jam.
