Theory of Operation
Manual Feed & Registration
■ Manual Feed No Paper Sensor (Photo Sensor)
Detects presence/absence of paper in the Manual Feed Slot by the
change in actuator position.
Upon detecting the sheet, the Regi Roller rotates for a predetermined
duration to feed the sheet. The sheet is caught between the Rollers so
that it may not fall from the Manual Feed Slot.
The Rollers stop immediately when the Registration Sensor detects the
presence of paper.
■ Registration Sensor (Photo Sensor)
The Registration Sensor detects paper when the paper leading edge
reaches the Registration Chute. When paper is fed from the Manual Feed
Slot, the Registration Sensor measures the paper length. The On time of
the Registration Sensor is converted into the paper length.
On: The paper activates the Actuator.
