The PF motor pinion gear
ASF hopper
rotates CW direction (right
release lever
side view), and the drive of
the PF motor is transmitted
to the LD roller shaft
through the Clutch lock
tooth and the Clutch gear.
After the LD roller pushes
down the Paper return plate
into the ASF frame, the ASF
hopper is released by the
tension force of the
Compression spring 2.50.
And, a paper is picked up
with the frictional force
between the LD roller and
the Pad hopper.

Overview
1
Paper return While the LD roller rotates
plate
CW direction (right side
2
view) continuously, the top of
a paper is loaded to the PF
roller. In this rotation, the
ASF hopper returns to the
open position and the Paper
return plate is released from
the LD roller. In this time,
this plate returns papers to the
stand-by position in ASF unit
for next paper loading
operation.
Then, when the rolling LD
roller & the Clutch come at
the above "Step1" position,
the Clutch lever is locked
with the Change lever again.
In this time, the drive of the
PF motor is interrupted and
the drive is transmitted only
to the PF roller side for the
paper feeding sequence.
