The by-pass feed table [A] can load only one sheet of paper.
When a sheet of copy paper is set in the by-pass feed table, the leading edge
of the copy paper activates the relay sensor [B] which sends a low signal to
the main board. The CPU energizes the relay roller clutch [C] after 500
milliseconds to feed the copy paper. Then, copy paper is fed from the 2nd
relay rollers [D] to the registration rollers [E].
