Digital ICE has NOTHING to do with, and is totally inappropriate for, the
subject of the original question, which was scanning PAPER DOCUMENTS.
Digital ICE is ONLY for scanning FILM (slides and negatives), and not even
all types of film.
Not true.
It works on paper also. It is just not called Digital ICE, Digital ICE is a
trademark name that belongs to Kodak.
There are software programs that perform the same functions as Digital ICE
on paper scans.
Polaroid has some software programs for dust and scratch removal.

Through HP Labs' innovative combination of hardware and software
technologies, HP scanners allow users to accurately recover slides,
negatives and prints that would otherwise be ruined.
There are other scanners that have the ability to remove dust and scratches
on paper scans.
My Canon Canoscan 8400F has the function in Advanced Mode. You can select
None, Low, Medium, or High.
