PAPER TRANSPORT DRIVE

The vertical motor [1] drives the timing belt [2] that rotates the transport roller [3].
The rotation of the transport roller also drives the paper feed roller when the paper feed
clutch engages the feed roller (not shown above).
The edge of the vertical encoder [4], attached to the shaft of the transport roller, passes
through the gap of the vertical encoder sensor [5] as the encoder wheel rotates. The vertical
encoder sensor reads the coded markings on the rim of the vertical encoder and sends this
information to the CPU. The CPU uses these readings to control the on/off timing of the
transport belt and the paper feed roller:
When servicing the machine, work carefully to prevent scratching, breaking, or
bending the vertical encoder wheel.
