Jams
The conditions for detecting whether a jam has occurred are stored in the puncher controller PCB in advance. A jam is determined
by detection states of the sensors at the check timing.
When the puncher controller PCB determines that a jam has occurred, it stops feeding/delivering paper and notifies the host
machine.
