Maybe using copy of the lexmark backend naming it lexmark2 or copy from
logitech1 backend (see http://gkall.hobby.nl/logitech-pagescan-usb.html)
to lexmark2 backend??
A quick check on your file seems that there are not many commands needed
to do a scan, so pasting into a backend will be not so much work.
I can take a look how i can paste it in a copy of the logitech1 backend.
