This machine uses a feed roller [B] and friction pad mechanism [C], with drive
from the main motor transmitted when the by-pass feed clutch [E] turns on.
The friction pad prevents all but the top sheet of paper from feeding.
Therefore, during paper feed, the top sheet of paper is separated from the
stack and fed towards the registration rollers.
Before placing the paper on the by-pass feed table, the user must lower the
by-pass feed table by using the lever [A]. This is to ensure that the paper is
placed between the friction pad [C] and the feed roller [D]. Then, before
starting to copy, the lever must be raised to move the paper stack into
contact with the feed roller.
When there is no paper on the by-pass feed table, the paper end feeler [B]
drops into the cutout in the by-pass feed table and the by-pass feed paper
end sensor is activated.
