Horizontal Registration Operation - Canon External 2/3 Hole Puncher-B1 Service Manual

Chapter 2
2) A hole is punched in the trailing edge of the second sheet.
When two holes are punched, the 3-hole puncher is fed reciprocally in the escape direction (hole puncher rise direction) as shown below.

2.2.4 Horizontal Registration Operation

Horizontal registration drive of the punch slide unit is performed by the horizontal registration motor (M62). The home position of the punch slide unit is detected
by the horizontal registration home position sensor (PI61). The punch slide unit detects the trailing edge of the paper by the trailing edge sensor (LED5, PTR5) and
horizontal registration sensors (LED1 to 4, SREG1 to 4) and is moved to the trailing edge position matched to the paper size.
The following shows horizontal registration operation.
1) When the leading edge of the paper from the host machine is detected by the trailing edge sensor (LED5, PTR5) on the puncher unit, the horizontal registration
motor (M62) starts to move the punch slide unit towards the front.
