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 :)
