4) Paper Separating Mechanism
The paper separating mechanism ensures that only the top sheet of paper is fed in by
separating the second sheet of paper from the top one. This is accomplished by the
Torque Limiter fitted to the Separator Roll shaft which stops the Separator Roll when
there is a change in friction between the Feed and Separator Rolls.
* For details of the paper separating mechanism, see "12-14. Drawer Paper Take-Up
Mechanism".
