3.1 Paper feed control

3.1.1 Paper lift plate mechanism

• The paper lift plate is pressed down into the locked position (in which the paper is loaded in position).
• Load a paper stack and then slide the tray into the main body. This unlocks the paper lift plate.
• The paper lift plate (paper stack) is pressed against the feed roller.
• The paper lift plate (paper stack) is pressed upward by the springs at all times.

3.1.2 Feed roller/vertical transport roller control

• The feed roller and vertical transport roller are rotated, which feeds paper from the lower feeder unit and conveys it further into the inside of
the main body.
1. The tray2 paper feed motor is energized to turn the vertical transport roller.
2. The tray2 paper feed clutch is energized to turn the feed roller.
3. The paper is fed in by the feed roller.
4. The paper fed in by the feed roller is conveyed onto the registration roller of the main body by the vertical transport roller.
5. When the tray2 paper feed sensor is activated and then the paper is conveyed onto a predetermined point in the paper path, the tray2 paper
feed clutch is de-energized, thus bringing the feed roller to a stop. The vertical transport roller thereafter takes charge of conveying paper
further.
6. When the trailing edge of the last sheet of paper moves past the registration sensor, the tray2 paper feed motor is de-energized to bring the
vertical transport roller to a stop.
