Scanning Circuit
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 TX Motor, Scanning
LED, Verification Stamp, Sensor Detection, and Solenoid Drive Control.
3. TX Motor Drive Circuit
TX Motor Drive Circuit is controlled by SLA7042M and SLA7044M (SCN PCB IC2, ADF PCB IC1).
