MX-4101N  PAPER FEED SECTION  F – 4
2.  Operational descriptions
A. Hand feed
The pickup roller moves up and down to press the paper surface,
separating the paper on the top of the paper bundle and sending it
to the paper feed roller section.
The paper feed roller feeds paper to the transport section to pre-
vent against double feed with the separation roller. The manual
paper feed clutch controls ON/OFF of the pickup roller and the
paper feed roller. Paper is sent to the resist roller by the manual
transport roller.
B. Tray paper feed
(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 tim-
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.
(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.
(4) 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.
