(1)Mechanism relation diagram
(2)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 pres-
sure 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.
(3)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.
(4)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.
