2. Types
The microprocessor identifies jams in the following conditions:
a. Delay Jam
Copy paper does not reach the appropriate sensor within a specific period of time, i.e., the sensor does
not turn ON.
b. Stationary Jams
Copy paper does not move past the appropriate sensor within a specific period of time after the sen-
sor detected the paper, i.e., the sensor does not turn OFF.
c. Residual Jam
Paper remains over a sensor at power ON, i.e., the sensor detects paper.
Note:
A jam will be identified if the front door, right, door, or delivery door is opened during copying or when
the cassette is slid out.
3. Sequence of Operations
