2.5 Stapler drive
The stapler assembly is mounted on the lower front side of the sorter transport
assembly. Copies discharged into the bins in the "Staple mode" can be stapled
automatically. In addition, manual stapling can be performed on copies placed
into the stack tray by pressing the the "Staple" button.
(1) The operational components in the stapler include the stapler swing motor,
stapler drive motor, stapler swing sensor, stapler swing home sensor, stapler
safety switch, paper detecting sensor, staple detecting sensor, and cam position
sensor.
(2) For stapling to begin, the staple detecting sensor (PS1) must detect staples in
the staple cartridge, and the sorters bin paper sensor (TX-1, RX-1) must detect
paper in the bins. The stapling sequence is as follows:
a) The bin motor (M1) correctly positions the bin assembly, the tampers tap
the paper.
b) The stapler swing motor (M4) drives the stapler to the stapling position as
detected by the stapler swing sensor (PS3).
c) The safety switch (MS6) confirms no foreign objects are in the bin, the
stapler's paper detecting sensor (PS6) confirms paper in the bin, and the
staple drive motor (M5) begins to drive. (If foreign objects are blocking the
stapler or paper has been removed, the swing motor (M4) returns the stapler
back to it's home position.)
d) Once the cam sensor (PS4) detects that the stapler drive has returned home,
the swing motor drives the stapler back to the stapler swing home sensor
(PS2).
e) Step a - d are repeated until the sensor bin paper sensor no longer detects
paper in the bin assembly.
(3) Safety protection is provided the stapler safety switch (MS6), if the paper holder
is moved more than 10mm (by foreign objects like fingers) the stapler drive
motor is disabled.
