By-pass Tray
The by-pass paper sensor [A] detects when paper is placed on the tray.
The CPU energizes the by-pass clutch [B]. Then the by-pass feed roller [C]
starts to feed paper to the registration roller [D] through the relay roller [E].
The by-pass feed roller shaft has two cams (1), (2). These cams release the
bottom plate to press the stack of paper against the by-pass feed roller.
There is no width sensor.
To prevent bad effects from too much friction between the feed roller and friction
pad, the by-pass feed roller contains a metal plate.
