3.13.7 Drive Mechanism with Stepper Motor
A stepper motor drives the total paper transport including the document feeder. Transport speed is
adjusted to the resolution selected and is trimmed via a parameter.
The drive system has the following components:
a stepper motor
a flat belt drive
a round belt
an electromagnetic clutch with gear
The stepper motor is mounted on the inside of the right hand side sidewall. Rubber elements are used to
provide cushioning.
This aids in noise reduction.
When a scan command is issued the stepper motor starts. A flat woven belt transmits the drive power to
the following parts:
- the first shaft of the paper return mechanism
- the two robber roller pairs
- the electromagnetic clutch that drives the initial feed rollers
- via a round belt to the push-back roller
Tension of the flat belt can be adjusted by moving the stepper motor. If tension is too loose the belt can
slip, which can result in distortion of the scanned image or the scanner issuing an 'over length document'
message.
The following illustration is a side view from the right showing the drive with the cover open.
