42 Finisher unit explanation ENWW
M705 (alignment/U) control
In the staple, folding, stitch-and-fold,
tri-folding modes, the widthwise alignment
operation of the paper carried into the
stacker section is performed 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 finisher CB (finisher
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 finisher operation signal from the
MFP 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
accommodated.
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.
