ADF Exposure Glass: No contact vs Contact
Originals that have sticky substances on the surface may cause streaks
on the exposure glass.
To prevent these streaks, the ADF exposure glass has a mylar, which
guides the original over the glass so that it does not contact the glass.
This method has one demerit: any dust that attached to the exposure
glass will stay there and will not be swept away by originals passing
through.
However, the dust detection feature described on the next few slides can
help with this.
The machine uses the no contact type, but it can be converted to a
contact type.

To convert between contact and no contact type scanning:

to Contact Scanning
The procedure is the same as in the MET-C1
