10.3.2 Paper separation mechanism

• Rotation of the transport motor is transmitted through the tray 1 paper feed clutch to thereby drive the feed roller.
• The feed roller rotates to take up and feed paper into the main body.
• Double-feeding of paper is prevented by the separation roller provided with a torque limiter.

10.3.3 Paper feed control

• Rotation of the transport motor is transmitted through the tray 1 paper feed clutch to drive the feed roller to take up and feed the paper.
• The paper taken up and fed in is conveyed onto the registration roller.
• The paper is pressed against the stationary registration roller so that a loop is formed in the paper. The feed roller is then stopped. The loop
thus formed in the paper corrects any mechanical skew in the paper.
• As the trailing edge of the paper reaches a point impapertely before the feed roller, the feed roller is stopped.

10.3.4 Paper empty condition detection control

• The paper empty message "PAPER EMPTY TRAY1" is displayed on the panel when the empty sensor actuator unblocks the tray1 paper
empty sensor.
• No mechanism is provided for detecting a paper near-empty condition. The paper supply level indicator replaces this function.
