CHAPTER 7 PICK-UP/FEEDING SYSTEM

2. Types of Jams

The microprocessor identifies the following conditions as Jams:
a. Delay Jam
Paper does not reach the sensor within a specific period of time (i.e., the sensor remains off).
b. Stationary jam
The sensor detects paper, but the paper does not leave the sensor within a specific period of
time (i.e., the sensor does not turn off).
c. Residual Jam
Paper exists over the sensor at time of power-on (i.e., the sensor turns on).
Caution:
The machine also identifies a jam when the front door, right door, or the delivery door is
opened or the cassette is slid out during copying operation.
3. Sequence of Operations
a. Pick-Up Delay jam
Paper turns on the vertical path clutch (CL3), but it does not reach the vertical path paper sensor
(PS11) within a specific period of time.
