Scanning Circuit
1.
Scanning LSI
MN860741 (IC18) is a Scanning LSI which generates Shading Correction, MTF Correction, Reduction/
Enlargement, and Gray Scale Error Diffusion. The Image Signal is converted to binary signal and
transported.
2.
TX/RX Motor Drive Circuit
Single Motor is used for TX/RX, which is controlled by Motor Drive Chip SMA7029M (IC26).
