More on Paper Size Detection
The side guides contain ratchets that turn a gear wheel at the center of the
sensor. The gear wheel contains terminals. The output of the sensor changes
when the gear wheel rotates over the wiring patterns on the rectangular part of
the width sensor.
The bypass tray hardware only determines the paper width. The base copier
hardware determines the length.
