2.1.4.1 MP Tray

Paper feeding from MP Tray

The power is transmitted from the transport motor (M2) as follows to take up paper from the MP.

1)The transport motor (M2) turns counterclockwise → 2)The idle gear turns clockwise. →The MP Cassette paper take-up solenoid (SL1) turns ON. → 3) The paper take-up roller turns counterclockwise. → Paper is taken up.
