B. Paper lifting operation
Set paper in the paper feed tray and insert the paper feed tray into the
machine. The lift plate lifts up.
Paper is lifted by the lift motor (CLUM).
When the paper feed tray 1 upper limit detector (CLUD1) detects the
top of paper, the lift motor (CLUM) stops and the contact pressure
between paper on the top and the paper pickup roller becomes the
proper level when paper is picked up.
When the paper remaining quantity is decreased, the lift plate lifts up
in each case to maintain the contact pressure between paper on the
top and the paper pickup roller at the proper level when paper is
picked up.
C. Paper size detection operation
This model does not have a function to detect the paper size in the
cassette.
The paper size in the cassette is changed on operation panel.

Function and operation
Function and operation
D. Paper feed operation
The paper feed motor (CPFM) is turned ON, and then the paper feed
clutch (CPUC1) is turned ON.
The power of the paper feed motor (CPFM) is transmitted through the
paper feed clutch (CPUC1) to the paper pickup roller and the paper
feed roller.
The paper pickup roller descends to pick up paper on the top and feed
it to the paper feed roller.
The paper feed roller feeds paper to the paper transport section.
At that time, the separation roller rotates to prevent double-feed.
