10.4 Operation
10.4.1 Up/down control
• The paper lift-up plate is moved up and down by the transport motor.
(1) Up operation
• The bypass pick-up solenoid is energized for a predetermined period of time during rotation of the transport motor. This unlocks the
paper lift-up plate clutch and the driving force of the transport motor is transmitted to the paper lift-up cam.
• As the paper lift-up cam rotates, the paper lift-up plate which has so far been pushed down by the paper lift-up cam is raised to the paper
feed position by the spring.
(2) Down operation
• The bypass pick-up solenoid is energized for a predetermined period of time during rotation of the transport motor. This rotates the paper
lift-up cam, so that the cam pushes the paper lift-up plate down into its standby position.
