4. Registration sensor stationary jam (for multi-feeder pick-up)
In the case of multi-feeder pick-up, if, after the multi-feeder pick-up solenoid (SL302)
has come ON from the second or subsequent sheet pick-up, the preceding paper has
not left the registration sensor (PS302) after approx. 1.0, it is judged that a registration
sensor stationary jam has occurred.

5. Paper leading edge sensor delay jam (for cassette pick-up)
If paper has not arrived at the leading edge sensor (PS301) approx. 1.2 seconds
after the registration clutch (CL302) has come ON, it is judged a paper leading edge
sensor jam has occurred.
