ADF and scanner operation

Flatbed scanner drive

The flatbed scanner has a scanner lamp that illuminates the surface of the document. The reflections produced
are processed to create the scan image.
For flatbed scan jobs, the flatbed scanner moves across the scanner glass area to scan the front side of the
document. The motor (scanner) drives the belt and controls the scanner position. The sensor (scanner home)
detects the scanner at its home position.
For ADF scan jobs, the scanner lamp stays at the left side to scan the document.
