Theory of Operation

2-35

The drum is driven by a closed-loop servo motor. Through a single reduction belt
drive, the servo motor rotates the drum at a high speed for imaging and a constant low
speed for image transfer to paper. The Y-Axis uses an active tension system to allow
the pulley to float while the spring actively adjusts the tension.

Note

The drum rotates in different directions for each process.

Warning

Always keep your fingers away from the drum drive system; it
uses a closed-loop servo drive system. Since the motor speeds
up if it senses the drum drive system slowing down, fingers
caught in the drum belts and gears can be severely injured.
