Scanning glass dust detection control

In the case of 2-side scanning with this equipment, dust and smudges on the scanning glass
(attached when scanning the back side) can cause lines on the image.
To prevent this symptom, there is a dust detection correcting function with this equipment.

This function makes the reader controller to shift the scanning glass to the scanning position

at detection timing for detecting the degree of smudges on scanning surface.

In the case of smudges detected at the scanning position, the scanner unit is shifted to

smudge-free position to prevent image fault.

There are 3 scanning positions to be detected in the order as shown below. If there is smudge
at the first position, the scanning position is shifted to the next scanning position to execute

scanning of the backside.

If smudge is detected at all 3 scanning positions, a user message is displayed to encourage
cleaning of the scanning glass (DF operation is available when this message is shown).
