Section II Operation
2.1 Normal feeding (copy)
• Original feeding begins with the last page.
(1) When the start button is pressed, the paper feed motor and pick-up solenoid
are energized. The pick-up roller moves down towards the stack of originals
and transports the original on the top of the stack to the paper feed roller. The
entrance gate is opened and the paper feed roller rotates to feed the original to
the registration roller. Double feed prevention is provided by the lower paper
feed/double feed prevention roller.
The paper feed motor stops a predetermined time after the lead edge of the
original passes by the registration sensor. The original is held in place by the
resistration roller.
(2) The transport motor is energized and the registration roller begins to rotate.
The original is then transported to the original holding roller.
The original is scanned as it passes between the original holding roller and the
platen glass.
The paper exit switching solenoid is then energized and the paper exit-switching
claw is switched to the upper paper discharge position.
After the trail edge of the original passes by the original holding roller, the
transport motor stops.

(3) The paper feed motor and pick-up solenoid are energized again. The pick-up
roller moves down towards the stack of originals and the next original is fed.
The paper exit rollers rotate to discharge the original. During paper discharge
the deceleration clutch is released to ensure that the paper is neatly stacked in
the exit tray.
