[3] M705 (alignment/U) Control
MAIN BODY
In the staple, folding, stitch-and-fold, three-fold-
ing modes, the widthwise alignment operation of
the paper carried into the stacker section is per-
formed by the alignment plate/U. The space
between the two alignment plates/U extends or
shrinks by means of the rotation of the M705
(alignment/U). The FNS CB (FNS control board)
controls the operation of M705 through the RB
(relay board).
The related signals are PS705 (stacker
entrance) and PS708 (alignment HP/U).
1. Operation
The FNS operation signal from the main body
lets M705 (alignment/U) rotate so that the space
between the two alignment plates/U will become
narrower. The rotation of M705 stops when the
plates reach their waiting positions that provide a
little wider space for the paper to be accommo-
dated.
When PS705 (stacker entrance) has detected
the trailing edge of the paper and a predefined
time period has elapsed, the alignment plates/U
horizontally oscillate to align the paper. The
oscillation is provided by the normal and reverse
rotations of M705. This paper alignment action is
repeated each time a sheet of paper is fed.
