6) Paper detection sensor : Detects the remaining paper in the tray.
Side fenceDriving Multi-Purpose Tray (MPT)
MPT can load 50 sheets of the standard paper. When opening the tray to load the paper, the
base plate goes down by a cam and positions where it is separated from the pickup roller in
orde to put the paper in easily.
When loading the paper, unfold the extension by pulling it to the most and load 50 sheets or
below in the tray and adjust the fences to fix the paper firmly.
When a feed signal is entered, the segment gear is relased by operating the solenoid and the
power of the main motor is delivered to the pickup roller in MPT. Accordinly, the rotation of the
pickup roller allows the cam move together and the base plate goes up by stength of the spring,
then the pickup roller contacts the paper generating a feeding power and starts to feed the
paper from the paper on the top.
If the pickup roller makes one rotation, the segment gear meshes with the solenoid and the
power of the main motor is blocked to stop the rotation of the pickup roller,and then the base
plate goes down again and return to home position.
The paper separation method uses the friction pads, and the friction of the pad and the pressure
of the spring separate the paper one by one sheet.
