What Happens If Dust Is Detected? - Ricoh B132 Service Manual

What Happens if Dust is Detected?

If dust is detected, the position where the scanner stops below the ARDF exposure
glass to scan the original is moved by 0.7 mm.
The scanning position can be shifted two times in 0.7 mm increments, towards the
scanning reference point at the upper left corner of the exposure glass.

If dust is detected after the scanner has been moved two times, an alert is
displayed, but the job does not stop.
Then, at the start of the next job, the scanner stays at position c. But if dust is
detected at c, the scanner goes back to home position (a) and the dust detection
process starts again.
