All the feed rollers and transport rollers (with the exception of the feed belt
drive rollers [A]) begin to rotate together with the feed motor [B]. The feed belt
drive clutch [C] is energized according to the appropriate original feed timing.
When the clutch is energized, the feed motor drive will be transmitted through
the gears [D] and timing belt [E], and the feed belt brake clutch shaft [F] to
the feed belt drive rollers. The feed belt brake clutch [G] stops the feed belt
rotation when the feed belt drive clutch is de-energized to prevent
multi-feeding of originals. When the feed belt brake clutch is energized,the
rotating clutch disk [H] is stopped by the clutch which is fixed on the frame.
