I've tried posting this twice. I'm breaking it up into parts to see if 
it posts.

My investigation of the CanoScan 8400F has so far found the following.

chips :

Scanner chip = GL843    [1]
  I'm trying to get the datasheet on this. It's not
  downloadable yet that I can see. I'll use the 842 datasheet for now.
  I suspect the main differences between the 842 and 843 are increased
  memory support and increased resolution support. The 8400F supports
  3200x6400 scanning and any transparency up to 6x22cm.

Samsung K4S6411632H-UC75, 64Mb, 4Mb x 16 x 4 banks  SDRAM = 8MB. [2]

Wolfson WM8199CDS image digitizer [3]

Allegro L6219DS Dual full-bridge PWM motor driver. [5]

A few other chips I didn't identify.
