- As part of operation after a pickup delay jam, the delivery sensor (PS3) detects paper, the laser is forced OFF, and
a specific period of time passes.
- At time of cleaning the fixing pressure roller, the trailing edge of paper does not move past the delivery sensor (PS3;
i.e., the sensor does not go OFF) within a specific period of time.
7.2.4 Other Jams

After the delivery sensor (PS3) has detected the leading edge of paper, the delivery sensor (PS3) detects the absence
of paper before a specific period of time.

- When the fixing heater is started, the paper leading edge sensor (PS102) detects the presence of paper.

under either of these conditions, the delivery sensor (PS3) detects paper within 2 sec after the fixing heater starts.
- The size of the paper last subjected to length detection is identified as being LTR or larger, and the delivery sensor
(PS3) detects paper within 2 sec after the main motor starts.
