2-52 Phaser 6121MFP Service Manual
Theory of Operation
The fixed Separation Pad system plus the Retard Rollers are used for paper
separation. This ensures that only one sheet of paper is fed.
Tray 1 Media Detection
Tray media empty/misfeed conditions are detected by the registration sensor.
To reduce the number of detected paper misfeeds, another feed sequence is
carried out if a registration sensor signal transition fails to occur within a
predetermined period of time. If after the second feed attempt media is not
detected, a media empty/misfeed condition is reported.
