Overview
The Start Power Chain comprises the

their mechanical drive systems. The Start Power Chain is activated when the user presses the
Start button on the User Interface with the machine powered.
The Main Motor operates at three speeds, depending on the type of blank media being pro-
cessed. Motor speed is controlled by the IOT CPUIOT CPU PWBA which uses its address and
data buses to write control data to decoder circuitry on the IOT Drive PWBA.

Main Motor
The Main Motor is a multispeed motor whose speed is controlled by a clock signal from the IOT
CPU PWBA. As shown in Figure 1, the Main Motor drives the following machine elements:
• The Mag Roller, the Auger, and the Pickoff Roll (BPO) in the Developer Subsystem
• The Intermediate Belt Transfer (IBT) Cleaner Cam and the IBT Cleaner Auger
• The IBT Second Bias Transfer Roller (BTR)
• The Waste Toner Auger, the Waste Toner Bottle Entrance Auger and the Toner Bottle
• The Photoreceptor (PR) Drum Brush, the PR Drum Cleaner Auger Rear and the PR Drum
Cleaner Auger Front
MAIN MOTOR
Motor speed is controlled by the IOT CPU PWBA which uses its address and data buses to
write control data to decoder circuitry on the IOT Drive PWBA. As shown in
vidual outputs from the decoders are sent through drivers to the motor.
