Finisher unit explanation
M720 (folding conveyance) control
M720 (folding conveyance) operates the
folding roller(s), which rotates the tri-folding
roller.
The finisher CB (finisher control board)
controls the operation of M720.
The related signals are PS722 (folding knife
HP), PS725 (folding paper exit), and PS726
(folding passage).
1 Operation
PS726 (folding passage) detects the
paper and the booklet stopper stops at the
folding position. After a predefined time
period has elapsed since then, M719
(folding knife) is activated. When PS722
(folding knife HP) detects the paper, M720
(folding conveyance) is activated to fold
the paper with the folding roller(s) and the
tri-folding roller. The folded paper is
delivered to the booklet tray.
When PS725 (folding paper exit) has
detected the trailing edge of the paper and
a predefined time period has elapsed
since then, M720 stops.
