Theory of Operation
Tray 2 Multiple Sheet Feed Prevention
The sheets loaded into Tray 2 are occasionally stuck together along the
edges, which can cause a multiple feed or a jam. The Nudger Roller feeds the
sheets to a position between the Feed Roller and the Retard Roller. Normally,
when only one sheet is fed, both the Feed Roller and Retard Roller rotate to
allow the sheet to pass.
