(3) Paper Supplied from MPT
1. In the usual case, sheet receiving is depressed by the arm for rise and fall at a
home position.
2. When a regist motor rotates in the direction of (b), the arm for rise and fall
drives and sheet receiving is rotated. The paper on sheet receiving goes up
to the position where a lift rise sensor is turned on, and feeding is attained
because the arm for rise and fall goes up.
3. The hopping motor is shared with the tray and MPT feeding uses the inversion
of tray feeding.
If a hopping motor reverse-rotates, a pickup roller and a feed roller will drive and
a paper will be sent out.
4. After an entrance sensor (2) is turned on by the paper tip, a paper is sent by
speciication length. A paper will stop, if the tip reaches the 2nd register strike
roller Assy.
5. A regist motor rotates in the direction of (a) simultaneously, and a paper is
conveyed with the 2nd regist roller Assy. A hopping motor is rotated until a
paper arrives at the position of the image drum cartridge (black).
6. A hopping motor is rebooted, in order to make paper feed to the following paper,
when an after the end escapes from the hopping sensor.
7. When operation of 4 to 6 is repeated and a lift rise sensor turns off, a regist
motor is rotated in the direction of (b), and the arm for rise and fall is driven,
and it goes up until a lift rise sensor turns on the paper on sheet receipt.
8. After the completion of paper sending operation, when a lift rise sensor detects
off, a regist motor is rotated in the direction of (b), and sheet receiving is
returned to a home position by dropping the arm for rise and fall.
