b-1) Cassette paper loading
In case of paper pick-up from the cassette, while the main motor rotates, the pick-up
solenoid (SL101) is turned ON. Then, cassette pick-up roller, cassette feed roller,
separation roller and feed rollers rotate, and a sheet of paper is fed into the fax.
In case of paper pick-up from the multi-purpose tray, while the main motor rotates, the
multi-purpose tray pick-up solenoid (SL102) is turned ON. Then, the multi-purpose pick-
up roller rotates, and a sheet of paper is fed into the fax.
NOTE
Loading operations
a) Maulti-purpose tray
When the ECNT board receives the nPRNT signal from the SCNT board,
the printer starts the initial rotation. When the initial rotation ends (main
motor warm-up, scanner motor warm-up, high-voltage control sequence,
and fixing unit warm-up are completed), the multi-purpose tray pick-up
solenoid (SL102) is turned ON.
As a result, the cam rotates, the lifter that paper is loaded is lifted, and the
paper comes in contact with the multi-purpose tray pick-up roller. At the
same time, the multi-purpose tray pick-up roller makes two rotations and a
sheet of paper on the multi-purpose tray is picked up.
b) Cassette feeder
When the SCNT board inputs the nPRNT signal to the ECNT board, the
main motor (M1) starts rotation. When the main motor reaches its
prescribed speed, cassette pick-up solenoid (SL101) are turned ON. As a
result, the cassette pick-up roller, cassette feed roller, separation roller and
feed rollers are driven by the main motor rotation.
The cassette pick-up roller makes one rotation with the pick-up solenoid
ON, and picks up the paper in the cassette. Then, the unnecessary sheets
are removed by the separation roller and the picked up paper is fed to the
pre-feed sensor (PS102).
