Yeah. Avision is one of the biggest scanner manufactors
delivering to a lot 
OEM companies, Kodak, Visioneer, HP, Oki, ... to name a few.
I think a Google 
search will reveal that Avision manufactures about 300.000
scanners per 
month ...

Changable background color?

Btw. some Fujitsu are also made by Avision

yes, the higher end fujitsus ($900+) have a
servo/solenoid-driven 
background behind the page, opposite the read head, such
that the driver 
can choose between a black or white background. when you
enable 
overscanning, this makes it quite easy to deskew the page.

i am aware. IIRC, FUJITSU (or at least FCPA) was AVISION's
first customer. 
remember that i have an sp15c for which i sent patches to
you
