1. Scanning LSI
MN86076 (IC51) is a Scanning LSI and generates Shading Correction, MTF Correction, Reduction/
Enlargement, and Gray Scale Error Diffusion. The Image Signal is converted to binary signal and
transported.
2. Scanning Mechanism Control CPU
M30620 is a 16 bit type of CPU that controls scanning mechanism. It controls Scanning Motor,
Scanning Lamp, Verification Stamp, Sensor Detection, and Solenoid Drive Control.
3. Scanning Motor Drive Circuit
Scanning Motor Drive Circuit is controlled by SLA7042M and SLA7044M
(SC PCB IC70, ADF PCB IC1).
