master eject jam occurs when the master eject sensor doesn't turn on at this time
Master Eject
The master eject sensor under the master eject roller detects master eject jams.
When the master eject sensor does not detect a master from the starting the drum
until the 2
nd
drum position sensor turns on, a master eject jam (B jam) will occur.
Then, the drum turns to home position, and the machine stops.
