Theory of Operation
Tray 3 Multiple Sheet Feed Prevention
The sheets loaded in Tray 3 are occasionally stuck together along the edges,
which can cause a multiple sheet 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.
