10-2. Image Processing Flow
• Image processing consists 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 MFB2 Board.
2. MFB2 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.
• Compresses the image data, stores it, and uncompresses it.
• The image memory has a standard capacity of 32MB for the 35-cpm copier and the 25-
cpm copier and 16MB for the 20-cpm copier, and can be expanded up to 64MB
(optional).
✽ 20-cpm copier: U.S.A. and Canada Only
3. PH
• Emits a laser beam according to the image data provided by the MFB2 Board to expose
thesurfaceofthePCDrum.
