Theory of Operation
Multiple Sheet Feed Prevention
2-20
The sheets in the tray are occasionally stuck together along the edges. The stuck
sheets cause a multiple sheet feed or a jam. The sheets are fed by the Feed Roller
to a position between the Feed Roller and the Separator Pad. Normally, when only
one sheet is fed, both the Feed Roller and Separator Pad rotate to allow the sheet
to pass. However, when two sheets are fed concurrently, only the Feed Roller
rotates and the Separator Pad is locked thereby allowing the upper sheet to
separate from the lower sheet that is stopped by the friction with the Separator
Pad at rest.
The Separator Pad is pushed toward the Feed Roller by spring pressure, and is
controlled by the torque limiter (Friction Clutch) with which it is coupled.
