4) After correcting displacement in horizontal registration, the machine uses the shift transport
motor to move the paper back to the punch unit and, at the same time, executes full
horizontal registration, in which the edge of the paper hits the stopper mounted to the
punch unit. The machine is now ready for punching.

Checking the Condition of the Punch Chip Case
The punch chip case detection mechanism consists of the punch chip case full sensor
mounted to the side of the punch chip case and a prism found inside the case.
The punch chip case sensor, on the other hand, is used to check the presence/absence of
the punch chip case.
The chips occurring as the result of punching operation are collected in the punch chip case,
and are monitored by a reflection type sensor (punch chip case full sensor). When the case
becomes full with chips, the main controller PCB suspends punching operation between
stacks (Memo), resuming the operation when the case is put back in place.

NOTE:
If the punch chip case is found to be full when the 2nd sheet of the 3rd set is being
handled while making 5 sets of 5 copies, the machine continues to operate until the 3rd
set is complete, suspending its operation at the start of the 4th set.
