Rear tamper motor
(MOT12-227)
Figure 14 Rear tamper components
Stapling: The stapling functions of the HVF, are distinct from those of the booklet maker and
are performed on each set immediately after compiling the last sheet of each set. A single,
travelling stapler unit is used. When 'one staple' is selected, the stapler unit remains at the out-
board end of its travel, and the corner of each set is stapled. When two or more staples are
selected, the stapler unit travels from outboard to inboard between each staple, then travels to
the mid home position where it remains during the tamping and ejection functions. The stapler
unit then returns to the home position. The components associated with the stapling function
are:
Principles of Operation
Rear tamper home
sensor (Q12-181)
Rear tamper away
sensor (Q12-183)
•
Stapler head motor, MOT12-247 - A DC motor that drives the closing of the stapler jaws
and the forming of the staple from a straight bar. The motor is an integral part of the sta-
pler and cannot be serviced. The high current to the stapler necessitates multiple wires
between the HVF PWB and the stapler unit.
•
Stapler primed sensor, Q12-134 - This is an integral part of the stapler and cannot be ser-
viced. It detects the staples in the correct position, ready for forming and stapling.
•
Cartridge sensor, Q12-317 - This is an integral part of the stapler and cannot be serviced.
It detects the presence of cartridge, correctly fitted in position.
•
Stapler jaw home sensor, Q12-318 - This is an integral part of the stapler and cannot be
serviced. It senses that the stapler jaws are correctly positioned, ready for a stapling
cycle.
•
Low staples sensor, Q12-133 - This is an integral part of the stapler and cannot be ser-
viced. It senses when the staples are running low and warns the user.
•
Stapler gate safety switch, S12-319 - This is described also in the paper pusher section,
in this document. The stapler gate safety switch is a micro switch located at the inboard
left of the paper pusher. This switch disables the +24V supply to the stapler motor drive
circuit, when the paper pusher is away from the lower position. This is to ensure personal
safety when it is possible to reach the stapler jaws, under the paper pusher. Refer to

•
Stapler unit home sensor, Q12-135 - A flag sensor, located at the outboard end of the bed
of the stapler unit. It detects the stapler unit in the home position. Refer to
•
Stapler unit mid home sensor, Q12-176 - A flag sensor, located towards the inboard end
of the bed of the stapler module. It detects the stapler at the inboard end of its travel.
