3. MISFEED CHECK TIMING
The first jam check (registration sensor ON check) is 299 pulses after the
paper feed solenoid turns on. If the paper has not arrived at the registration
sensor by this time, the CPU determines that there has been a misfeed.
The counter for the second jam check (the exit sensor ON check) starts
when the registration clutch turns on. If the paper does not activate the exit
sensor before the count reaches 582 pulses (3.7 seconds) a jam condition
exists.
The counter for the third jam check (the exit sensor OFF check) starts when
the exit sensor turns on. If the exit sensor is still on 563 pulses (for A4 or let-
ter copies) after the paper activates it, a jam condition exists. (The
check is at 658 pulses for folio or legal size copies.)
