Details of the optical system
In the optical system process, the printer utilizes a semiconductor laser diode as a light source. This laser diode is controlled by fast switching which matches the transmitted image data (video signal).
The generated laser light scans the OPC belt through a polygon mirror and lens. The electrostatic latent images are formed on the OPC belt.
The Optical printhead unit consists of following parts:
No. | Description |
|
|
1 | PD: photo detector |

2 | Polygon mirror: hexahedral mirror that reflects the laser beam |
|
|
3 | Cylinder lens: laser beam condenser |
|
|
4 | Laser unit: laser diode light emitting source |
|
|
5 | LDC: laser diode control circuit |
|
|
6 | BTD mirror: beam timing detector mirror to guide the laser beam to PD |
|
