CHAPTER 3 SADDLE STITCH UNIT BASIC OPERATION
D.
Aligning the Sheets
The alignment motor (M5S) drives the alignment plates each time a sheet is output, putting
both left and right edges of the sheet in order. The alignment plate motor is a 4-phase stepping
motor. The position of the alignment plate is identified in reference to the number of motor pulses
from the alignment plate home position sensor (PI5S).
The following briefly describes what takes place when the saddle stitching mechanism oper-
ates on two sheets.
1) When the first sheet has been output, the alignment plates butt against the left and right edges
of the stack (first alignment). The alignment plates leave the home position in advance and
remain in wait at points 10 mm from the edges of the stack.

2) The alignment plates move away from the edges of the stack over a short distance and then butt
against the edges once again (Second alignment).
