its home position every paper and step 1 to 6 are repeated.
Hole punching operation (2-hole/3-hole puncher assembly)
The 2-hole/3-hole puncher assembly punches 2 holes or 3 holes in the trailing edge of paper. Five
off-centering cams are on the hole punch shaft; two off-centering cams with punch for 2-hole
punching and three off-centering cams with punch for 3-hole punching.
The sensor flag is also on the hole punch shaft, and the hole punch home position sensor detects the
home position of hole punch shaft. The hole punch home position for 3-hole punching is shifted 180
degrees from the hole punch home position for 2-hole punching. When the hole punch shaft is at
