b. 2-/3-Hole Type
The home position is identified when the Punch Home Position Sensor is ON. To make two holes,
the punching operation for the first sheet ends when the Punch Shaft rotates 180° (half
circumference) and the Punch Home Position Sensor goes ON. At this time, the 3-Hole Puncher
makes a single round trip in escape direction (moving up the Hole Puncher) on a half circumference
of the Punch Shaft.
The punching operation for the second sheet ends when the Punch Shaft has rotated 180° counter-
clockwise and the Punch Home Position Sensor goes ON (half circumference). At this time, the 3-
Hole Puncher makes a single round trip in escape direction (moving up the Hole Puncher) on the
other half circumference of the Punch Shaft.
The punching operation takes place as follows when making two holes in two sheets of paper:
1) A hole is made along the trailing edge of the 1st sheet.
While two holes are being made, the 3-Hole Puncher makes a single round trip in escape
direction.
2) Holes are made along the trailing edge of the 2nd sheet.
