11.1.3.3.3. Controlling the Movement of Sheets
When the leading edge of a sheet has moved past the Inlet Flapper, the Intermediate Feed Roller and the
crescent Roller start to move the sheet forward.
The Intermediate Feed Roller is normally not in contact with the Path Bed. When the leading edge of a
sheet reaches the Intermediate Feed Roller contact section, the Feed Plate contact Solenoid (SL4S)
causes the roller to come into contact with the Path Bed so as to move the sheet. The contact is broken as
soon as the leading edge of the sheet reaches the Paper Positioning Plate. This series of operations is
executed each time a sheet arrives.
When the leading edge of the first sheet reaches the Paper Positioning Plate, the Paper Positioning Plate
Paper Sensor (PI18S) turns ON. The arrival of the second and subsequent sheets will not be checked since
the first sheet will still be over the sensor. The Crescent Roller keeps rotating while the sheets are being
output, butting the leading edge of each sheet against the Paper Positioning Plate, and ultimately, keeping
the leading edge of the stack in order.
The Alignment Plate Motor (M5S) drives the Alignment Plates for each sheet so as to set both left and right
edges of the sheet in proper alignment.
1. The Solenoid turns ON while the paper is being moved so that the Feed Plate comes into contact.

2. The Solenoid turns OFF when the paper butts against the Paper Positioning Plate. The Feed Motor
continues to rotate.
