A. Standby position movement of the punch unit
In the punch mode, the punch unit [5] is set to the standby position in accordance with the paper size before the
paper [3] is conveyed.
The punch shift motor (M5) [1] moves the punch unit so that the sensor corresponding to the paper size among
5 sensors of the paper edge sensor board (PESB) [6] (in case of A4 paper, the sensor [7] is used) is positioned 5
mm [9] inward from the side edge of the paper [8].
This operation is not conducted in the no punch mode.
