Scanning System 

This printer employs a semiconductor laser diode as a light source. This laser diode is 
switched according to the transmitted image data (video signal). 

The generated laser light scans over the OPC belt through a polygon mirror and lens, by 
which method electrostatic latent images will be formed on the OPC belt. 

(1) 

Structure of the Scanning System (Refer to Fig.4-24.) 

The scanner unit is located as shown in Fig.4-8. 

The scanner unit consists of the following parts; 

c

Laser Unit: 

Light emitting source incorporating a laser diode. 

d

Cylinder Lens: 

Condenser for the laser beam. 

e

Polygon Mirror: 

Hexahedral mirror for scanning the laser beam. 

f

F-

6

 

Lens: 

Focus lens for the laser beam. 

g

Scanner Motor: 

Motor to rotate the polygon mirror. 

h

Mirror: 

Reflecting mirror for the laser beam path. 

i

LDC: 

Laser diode control circuit. 

j

PD: Beam 

detector. 

k

BTD Mirror: 

Beam timing detector mirror to guide the laser beam 
to the PD sensor.
