4.8 PUNCH UNIT (OPTIONAL)
The punch unit punches holes in printed sheets, one by one. The punch unit is
provided with a new punch mechanism to improve the accuracy of punching.
4.8.1 PUNCH DRIVE MECHANISM
The punch drive mechanism is driven by the punch motor [A]. Each sheet is
positioned and punched by pressure from above. A certain time after the trailing
edge of the paper passes through the finisher entrance sensor [B], the punch motor
turns on and the paper stops. Then the punch clutch [C] turns on to make the
punch holes.
The home position is detected by the punch HP sensor [D]. When the cut-out in the
punch shaft disk [E] enters the punch HP sensor, the punch clutch turns off.
When the finisher has received the command that changes the number of punch
holes, the punch hole motor [F] turns on until the disk changes the status of the
punch hole switch [G] (until it switches on or off). This indicates that the cover [H]
and the punch cam [I] have moved to one side or the other to change the number
of holes.
