This feature checks the ADF exposure glass for dust that can cause black lines
in copies. If dust is detected, a message is displayed, but the process does not
stop.
Dust Detect: On/Off: Front

Issues a warning if there is dust on the narrow scanning glass of the ADF when
the original size is detected before a job starts. This function can detect dust on
the white plate above the scanning glass, as well as dust on the glass. Sensitivity
of the level of detection is adjusted with SP4020-002.

Before switching this setting on, clean the ADF scanning glass and the
white plate above the scanning glass.

not detected and the warning remains on.

on the ADF exposure glass).
