When paper is placed on the tray, the by-pass tray paper feeler [A] is pushed up
and the actuator leaves the by-pass tray paper sensor [B].
After image processing in the printer control board, the CPU energizes the by-pass
feed solenoid and the by-pass feed roller [C] starts to feed paper to the registration
roller [D]. The by-pass feed roller has two cams [E] and these cams release the by-
pass tray bottom plate to press the stack of paper against the by-pass feed roller.
This machine uses a feed roller and friction pad mechanism, with drive from the
main motor transmitted when the by-pass feed clutch turns on. The friction pad
only allows the top sheet to feed to the registration rollers.
When the paper leading edge activates the registration sensor [F], the registration
clutch [G] turns on.
