2.5 Stapler drive
Copies discharged into the bins in the "Staple mode" can be stapled by stapler
assembly automatically. In addition, manual stapling can be performed on copies
placed into the bin tray by pressing the the "Staple" key.
(1) The operational components in the stapler include the stapler swing motor,
stapler drive motor, staple position sensor, stapler swing position sensor, stapler
safety switch, cartridge detecting sensor, staple detecting sensor, stapling
position detecting sensor, and stapler.
(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 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) Stapler motion is detected by stapler swing position switch. (The cam connected
to stapler drive gear turns the switch on and off) When stapling fails by staple
jam etc., stapler drive motor returns to the initial position, and sends signals to
the main unit.
