1 Operation
a Interlock control
Finisher paper conveyance drive control
is initiated by the ON signal from the
MFP's START button. If MS701
(interlock) is off at this time, however,
the finisher transmits an error signal to
the MFP's PRCB and does not begin
this control.
b M701 (finisher conveyance) control
When the position of the START button
is on, and the paper exit speed is high,
ON from PS37 (MFP paper exit) sets
the speed to low, and ON from PS704
(finisher entrance) sets the speed to
high after a predefined time period. For
the main tray paper exit operation,
PS704 detects the end of the paper,
and, after a predefined time period, the
speed mode switches to medium to
match the paper exit speed of the
finisher. Then, after a predefined time,
the mode returns to the high speed to
prepare for the next conveyance of
paper.
