Exit diverter solenoid, SOL12-225 - Actuates to divert the paper from the buffer to the top
tray. In the non-actuated condition, it allows the paper to pass to the stacker. Refer to

Top exit sensor, Q12-107 - A flag sensor located in the upper exit paper guide. It senses
paper passing out to the top tray. Refer to

Compiler exit sensor, Q12-106 - A reflective sensor located on the top jam clearance
paper guide. It senses paper passing out to the stacker. Refer to
Compiler
This section includes the functions of paper pusher, upper and lower paddles, tamping, sta-
pling, paper ejection, pressing and support.
Paper Pusher: The final roll at the stacker exit, (see
stiffness. The paper pusher moves down as each sheet leaves the final roll, and pushes the
sheet down to the ejector unit. The components associated with the paper pusher are:
•
Paper pusher motor, MOT12-265 - A stepper motor located at the inboard end of the com-
pile exit upper guide. The motor drives pinions that engage with racks integral with the
pusher. Refer to

Paper pusher upper sensor, Q12-092 - A flag sensor that detects the pusher in the upper
position. Refer to

•
Paper pusher lower sensor, Q12-094 - A flag sensor that detects the pusher in the lower
position. Refer to
Figure
•
Stapler gate safety switch, S12-319 - A micro switch located at the inboard left of the
paper pusher. This switch disables the +24V supply to the stapler 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
Fig-
Figure 8 Paper pusher components
Upper Paddle: As the paper pusher moves down with the first sheet, the paddle unit moves to
the lower position. As the paper pusher returns to the upper position, ready for the next sheet,
the paddles rotate to position the first sheet correctly in the ejector. The sheet is correctly posi-
tioned when its trailing edge is in contact with the upright posts in the stapler module.
The number of cycles the paddle rotates depends on the size and orientation of the paper. The
paddle unit remains in the lower position and every sheet in the set is positioned in this way.
When the final sheet in the set has been positioned by the paddle, the paddle unit returns to
the upper position.
