M713 (stacker entrance) control
M713 (stacker entrance) drives the stacker
entrance roller and the swing belt. These
components are responsible for conveying
the paper to the stacker, aligning the paper
rear end, and controlling the timing for
stapling.
The finisher CB (finisher control board)
controls the operation of M713 through the
RB (relay board).
The related signals are PS704 (finisher
entrance), PS705 (stacker entrance), and
PS725 (folding paper exit).
1 Operation
a Staple mode (for sheets of all paper
sizes except A4, B5, and 8.5 by 11 =
without bypass feature)
The finisher operation signal from the
MFP lets M713 (stacker entrance) start
to rotate at a high-speed.
When PS705 (stacker entrance) has
detected the rear end of the paper, the
rotation speed of M713 changes to low,
conveying the paper slowly to the
stacker. Then, after a predefined time
has elapsed, the rotation returns to the
high-speed mode to prepare for the next
conveyance of paper.
When the last sheet of the set has
passed through and the stapling
operation has started, M713 stops.
When M708 (paper exit) has closed the
opening, the rotation of M713 changes
to a high speed to prepare for the
conveyance of the paper to be stapled.
b Staple mode (for sheets of paper sizes
A4, B5, and 8.5 by 11 = with bypass
feature)
1 Sheets of the first set
The sheets of the first set are
processed in the same way as in the
staple mode described above (for
sheets of all paper sizes except A4,
B5, and 8.5 by 11 = without bypass
feature).
