(8) Staple unit
The stapler staples paper. The ST shift motor slides the stapler
horizontally with the paper lead edge according to the staple positions
(forward, backward, 2 positions).
The ST rotating motor (STTM) rotates the stapler from the save position
to the stapling position, and can slide the staple replacement position
horizontally and can discharge paper.
(9) Stapler
The stapler can staple max. 30 pages of 80g paper. It is composed of the
drive DC motor (STM), the home position sensor (STHP), the staple
empty sensor (STLS), the cartridge empty sensor (STNC), and the self-
priming sensor (STSP) which detects a staplable position.
(10) Stapling
1) The stapler is moved from the staple replacement position to the
slidable position.
2) The stapler is shifted to the stapling position.
3) The stapler is rotated to the stapling position.
Put paper to be stapled in the staple tray.
4) Paper is stapled.
5) The stapler is rotated to the standby position.
When in one-position stapling, a bundle of paper is discharged to the
tray 2 (paper exit section), and the procedure goes to (10)
6) The stapler is shifted to the second stapling position.
7) The stapler is rotated to the stapling position.
8) Paper is stapled. (Second stapling)
9) The stapler is rotated to the standby position.
The bundle of paper is discharged to the tray 2 (paper exit section)
10) After completion of a job, the stapler is shifted to the staple
replacement position.
11) The stapler is rotated to the staple replacement position.
For one-position stapling, however, procedures (6) - (10) are not
performed.
(11) Paper exit after stapling
1) The joggers F/R are moved to the paper exit position.
2) The stopper solenoid is turned off.
3) The pressure release solenoid is turned on to shift the pusher to the
paper exit position, and the paper bundle is discharged to the tray 2
paper exit section.
4) The pressure release solenoid is turned off and the pusher is
returned to the home position.
C. Tray 2 paper exit section
(1) Paper transport
Only in paper exit to the tray 2, the final roller is driven by rotating the
paper exit motor (T2OM).
(2) Elevator operation and tray 2 paper full detection
The elevator motor is rotated to move the tray 2 up and down so that
paper is discharged at the fixed position according to the quantity of
paper loaded in the tray 2.
The tray 2 full is detected when both the tray 2 upper limit sensor which is
linked with the tray 2 upper limit actuator and the tray 2 lower limit sensor
are on.
