(2)Polygonal motor unit

This unit consists of the polygonal motor, polygonal mirror and polygonal mirror cover. a. Polygonal motor

8

This motor rotates the polygonal mirror in high speed.

The DC motor controls the rotation speed of the mirror motor as follows:

During ready: 10,000.00 rpm

During printing: 38,090.55 rpm (600dpi)

:38,951.37 rpm (FAX 15.4 ⋅ 16.0 dot/mm)

:37,490.70 rpm (FAX 16.0 ⋅ 15.4 dot/mm)

b.Polygonal mirror

One laser beam emitted from the laser diode is reflected by this mirror. As the polygonal mirror is rotated by the po- lygonal motor, the reflected laser beam moves in sync with the rotation. The direction of the movement is the primary scanning direction of the image. One scan is performed on one plane of the polygonal mirror.

As the polygonal mirror has eight planes, eight scans are performed in one rotation of the polygonal mirror.

c.Polygonal mirror cover

Polygonal mirror cover reduces the wind- age loss and noise, prevents adhesion of foreign objects onto the mirror surface and releases heat.
