Paper Fed From The Multi-Purpose Tray - Xerox 7300B - Phaser Color Laser Printer Service Manual

Paper Fed from the Multi-Purpose Tray

1. The hopper-plate is pushed down by the release lever to signalling the MPT roller
home position sensor (A).
2. The registration motor rotates in the direction shown, driving the MPT feed roller
causing the cam to turn. The cam pushes the release lever allowing the hopper
plate to pick the paper from the MPT feed roller. At this time, the registration roller
assembly does not move, as its one-way clutch gear idles.
3.
After the transfer belt entrance sensor senses the leading edge of the paper, the
paper is transported forward for a specified length. The paper stops when its
leading edge reaches the registration roller assembly (A).
4. Concurrently, the cam pushes down the hopper plate, which is locked by the
spring-loaded release lever (C).
5.
After completing the paper feed operation, the registration motor rotates to drive
the registration roller assembly (A). During this time, the MPT feed roller does not
rotate because of the one-way clutch gear.
