MX-C250 OPERATIONAL DESCRIPTIONS 11 – 10
6. Paper feed tray section
A. Electrical and mechanism relation diagram
B. Paper lifting operation
This model feeds paper from the top of the paper stack in the feed
tray. The paper lift plate lifts the paper stack to the feed roller by
way of a spring under the plate. A constant pressure of the top
sheet of paper to the feed roller is maintained through use of this
mechanism. This model also incorporates a paper empty detection
sensor but does not have a paper remaining detection mechanism.
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.
D. Paper pick up operation
The fusing drive motor (FUM) is turned ON, and then the paper
feed clutch (CPUC1) is turned ON.
The power of fusing drive motor (FUM) is transmitted through the
paper feed clutch (CPUC1) to the paper transport roller and 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.
To prevent a double feeding, the separation roller apply counter
force to the paper from bottom side.

Paper feed roller (Paper feed tray 1)
Paper feed roller feeds the top piece of paper in the cassette to the registration roller set in
the machine.
