CHAPTER 2 OUTLINE OF OPERATION
6.2.2 Punching Operation
The hole puncher is driven by the punch motor (M1P). The home position for the hole
puncher is detected by the punch home position sensor (PI1P).
The punch unit comes in four types, selected to suit the country of installation: 2-hole
(Puncher Unit-J1), 2- and 3-hole (Puncher Unit-K1), or two types of 4-hole (Puncher Unit-
G1, Puncher Unit-H1).
The 2-hole and 4-hole types punch a hole when the punch shaft is rotated 180° from the
home position, causing the punch to make a single round trip. The 2-/3-hole type punches a
hole, but the circumference of the punch shaft is divided into two (half for 2-hole and the
other half for 3-hole).
