2.9 RELAY ROLLER AND POSITIONING PLATE
MECHANISM
When the first sheet of paper comes to the booklet unit, the
booklet transport motor turns on to drive the relay roller [A].
The two relay rollers are out of contact with each other before
the paper comes. When the leading edge of the paper passes
trailing edge sensor 1, the relay roller solenoid is energized to
make the two relay rollers contact each other to transport the
paper to the positioning plate [B]. When the trailing edge of the
paper passes to the trailing edge sensor, the relay roller
solenoid is de-energized. This solenoid on/off cycle is done for
each sheet of paper.
Before paper comes, the positioning plate moves up from the
home position to a position that is suitable for the selected
paper size in order that the middle of the paper just comes to
the stapling position.
The positioning plate motor drives the positioning plate using
pulse counts.
Only when the first sheet of paper reaches the positioning
plate, the positioning plate sensor [C] detects the paper.
