11.1.3.3.4. Aligning the Sheets
The Alignment Plate Motor (M5S) drives the Alignment Plates each time a sheet is ejected, setting both left
and right edges of the sheet in proper alignment. The Alignment Plate Motor is a 4-phase stepping motor.
The position of 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 operates on two
sheets.
1. When the first sheet has been ejected, the Alignment Plates butts against the left and right edges of
the stack (first alignment). The Alignment Plates leave the home position in advance and remain
separated by 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 (2nd alignment).
