MX-FN19 OPERATIONAL DESCRIPTION 6 – 11
I. Aligning the sheets
The alignment plate motor (FSJM) 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 (FSAHPD).
The following briefly describes what takes place when the saddle
stitching mechanism operates on two sheets.
1) When the first sheet has been output, the alignment plates butt

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 (FSAHPD).
The following briefly describes what takes place when the saddle
stitching mechanism operates 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.
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).
again (Second alignment).
3) The alignment plates escape to points 10 mm from the edge of
the stack.
4) When the following stack arrives, steps 1) through 3) above
are repeated.
5) The alignment plates butt against the stack once again, during
which stitching takes place.
6) The alignment plates escape to points 10 mm from the edges
of the stack, after which folding and delivery take place.
7)
When the first sheet of the following stack reaches the No.1
paper sensor, the guide moves to a point 10 mm from the edge
of the stack to be ready for the next alignment operation.
