The original separation system uses an FRR (Feed and Reverse Roller) system.
The pick-up roller [A], feed belt [B], and separation roller [C] are driven by the feed-
in motor [D].
To drive this mechanism, the feed-in motor turns in the forward direction.
When two sheets of the original are fed by the pick-up roller, the separation roller
turns in the opposite direction to the feed belt and the 2nd sheet is pushed back
towards the original tray. When there is only one sheet between the feed belt and
separation roller, the separation roller rotates in the same direction as the feed belt.
This is because the separation roller contains a torque limiter.
