Ver.1.2
c. The paper is transported to the Registration Roller (1121), activating the Registration Sensor (1045).
d. After a specified period of time, the Clutch (1105) is turned ON and the Registration Roller (1121)
and the Registration Pinch Roller start rotating. The paper is transported to the OPC Drum area.
After lowering the Pressure Plate (1295) during the specified period of time, the Clutch is turned
OFF and the Feed Roller (1244) stops rotating.
e. After the trailing edge of the paper passes the Registration Sensor (1045) and after a specified
period of time, the Clutch (1105) is turned OFF. The Registration Roller and the Registration Pinch
Roller stop rotating.

Laser Unit
1. Laser
This Laser uses the semiconductor laser. The beam power on the drum surface is approximately 0.4
mW.
2. Collimator Lens and Cylindrical Lens
These lenses converge and focus the laser beam, converting it to parallel light.
3. Aperture
This controls the size of the laser beam.
4. Polygon Mirror and Polygon Motor
The polygon scanner consists of a 6-sided mirror, directly driven by a DC motor, revolving at 42,000
rpm. The laser beam is reflected against these mirrors and swept over the recorded width in the
scanning direction.
5. Beam Detection (BD) Lens and Beam Detection (BD) Sensor
The BD Lens receives the reflected light from the Polygon Mirror and redirects it into the BD Sensor,
which converts the laser beam into electrical signals and sets the start timing for the scanning line.
