Punch standby position movement control

Turning ON the device, the punch shift motor (M302) rotates to move the punch unit [6] to the home position
until the punch shift home sensor (PS303) turns ON.
Selecting the punch mode, M302 rotates to move the punch unit [6] so that the paper size sensor (PS305) [1] of
the punch unit [6] is positioned 5 mm inward [2] from the side edge of the paper.
PS305 consists of 5 sensors. Each sensor detects the following paper.
Sensor
1 A5S, 5

2 B5S, 16KS
3 A4S, A5, 8
4 B4, B5, 8K, 16K
5 A3, A4, 11 x 17, 8
* The sensors are numbered 1 to 5 from the front side
And, when the stand-by position is 5 mm for B5 and B4 paper sizes, the corner of the paper passes through
below the punch hole and the stand-by position is changed to 1.5 mm to prevent the hitching of the paper.
The punch unit returns to the home position at the end of the job.
