Principles of Operation
Figure 20 Hole punch components
• Chad bin present sensor, Q12-118 - A flag sensor, detecting the presence of a chad bin,
under the hole punch module. Refer to
Figure 21 .
• Chad bin level sensor, Q12-193 - A reflective sensor, detecting the presence of chad,
through a hole, high in the side of the chad bin. Refer to
Figure 21 .

Tray 6 Inserter
The Inserter, enables the user to insert a sheet at a pre-defined point in a set. For example it
may be used to insert cover sheets or separators. The media inserted can be hole-punched,
stapled or folded, as required. The active components of the Inserter are:
• Inserter motor, MOT12-261 - A stepper motor, located at the rear of the inserter. This
motor runs forward to drive the paper tray up and to feed the paper, and the motor runs in
reverse to drive the paper tray down. This is a variable speed motor, under the control of
the software. The variable speed is used to synchronize the inserted media with the
printed sheets coming from the IME, and compensates for any speed mis-match. In the
forward direction, this motor turns the retard roll in the reverse direction, via a torque lim-
iter. The retard roll thus acts as a retard pad, continually renewing its point of contact with
the paper, thereby increasing its life and effectiveness. Refer to
Figure 22 .
• Inserter clutch, CL12-260 - Located at the rear of the inserter, this clutch passes the drive
to the feeder roll and nudger roll. Refer to
Figure 22 .
• Inserter Pickup sensor, Q12-315 - A reflective sensor, located on the underside of the
inserter top cover. The pickup sensor controls the electric clutch to start feeding. Refer to
Figure 22 .
