Here's my  two cents worth:  I use the Epson 3200 and E2450 scanners. Their 
florescent lamps  work just like a cold light head on an enlarger to reduce 
grain, dust, and scratches.  So far I've had no problems with 35mm TX or 
other B/W films.  Chromogenic B/W film works very well too.  BTW I develop 
it in D76 at home.  I print with the piezo system.  Check out this taken 
with XP2 and processed with split D-76: 
http://www.panoramacamera.us/air_support.html  It has wide latitude and low 
grain, and printed like a charm.
