B. Operational descriptions
(1) Paper feed front operation
• Set paper and insert the paper feed tray, and the pickup roller falls to turn ON the paper feed tray sensor.
• The lift-up motor drives the rotating plate to move it up.
• The paper upper limit sensor turns ON, and the rotation plate stops at the specified position.
(2) Paper feed operation
• When copy/print operation is started, the motor and the clutch are turned ON to rotate the pickup roller in the paper pickup timing, feeding
paper.
• At the same time, the paper feed roller rotates to transport paper to the transport section. At that time, the separation roller rotates to prevent
against double feed of paper.
(3) Paper remaining detection
The notifying levels of paper remaining quantity are 4 steps in total; 3 steps of paper remaining quantity and 1 step of paper empty. The result
is displayed.
