Dirt Sensor Control
Overview
The machine changes the original read position or corrects the read image depending on the
presence/absence of dust on the stream reading glass or ADF platen
roller, thus preventing dust from showing up in the image. This control is performed only when
the ADF is used and it is closed.
[Control Timing]
- At job end
- Immediately before scanning (one sheet at a time)
