•
Image processing is made up of the following blocks.
1. Photoelectric Conversion (CCD Sensor)
•
Light reflected off the original is received through mirrors and lens by the CCD Sensor
which, in turn, outputs the corresponding data to the HGB Board.
2. HGB Board
•
After converting the data received from the CCD to an analog signal, the board converts
it to 8-bit image data (A/D conversion). It further makes various corrections and outputs
the resultant image data to the MFB Board over an optical cable.
3. MFB Board
•
This board compresses the image data received from the HGB Board, stores it, and
uncompresses it.
•
The image memory has a standard capacity of 16MB and can be expanded up to 64MB
(optional).
4. PH
•
Emits a laser beam according to the image data provided by the MFB Board to expose
the surface of the PC Drum.
