SEPARATION MECHANISM

-----
Coefficient
----- Coefficient of friction between the friction rollers and the original.
----- Coefficient of friction between originals.
This model uses an FFR (Feed and Friction Roller) original feed system with
three sets of rollers (feed, friction and pick-up roller). The feed [A] and friction
rollers [B] have grooves in them which interlock with one another. The rollers
interlock to decrease damage to the originals [C], especially pencil written
originals, from direct roller-to-roller pressure.
The pick-up roller sometimes sends more than one original to the feed and
friction rollers. When this happens, the friction rollers strip the extra original
originals are stopped.
