Maybe there's an unspotted error somewhere, the perfection
610 is a tricky scanner and there are some sections of the driver
dedicated to its handling.
However, I was unable to test it personally since I do not
own such a scanner.
If you search for "color shuffle" in the code you'll see
that the scan area gets modified for the 610 because the color
shuffling algorithm will eat some data.
For such a scanner, I'd suggest to scan a bigger area
and then refine by software.
