b. 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 tim-
ing, feeding paper.
ing, 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.
to prevent against double feed of paper.
c. 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.

d. Paper remaining quantity detection method
• The paper remaining quantity is judged from the number of rota-
tions of the remaining quantity sensor from starting the lift-up
operation of the paper feed tray to turning ON the upper limit
sensor.
