Tray up/down mechanism

The driving force of the tray motor transmits to the tray driving pulley through the gears. Moving the tray moves

up and down through the tray driving belt. After the paper loads, and the top cover is set, the pickup solenoid

turns on to lower the call roller. When the tray moves up, the call roller is raised by the top surface of the paper,

and the shield plate on the up sensor is released from the up sensor which turns off the tray motor.

Also, when the top surface of the paper lowers during printing and the up sensor is shielded, the tray motor again

rotates forward to raise the paper.
