• The major changes include the elimination of the memory compression/de-compression

• The rest of the image processing system are the same as those of the CLC1000 Series ma-
chines.
The image processing system consists of the following:
• CCD line sensor used to convert light reflected by the original into analog video signals.
• analog processor PCB used to generate digital video signals from analog video signals.
• PCBs (image processor PCB, IP memory board, ED board) used for various correction
and processing on digital video signals.
