[sane-devel] Canon laser multi-functional support: MFNP protocol

[Rolf Bensch]

Hi,

The MF6100 Series scanner is only working with flatbed scans and with
single page scans in adf.

Just now, I'm struggling with multiple pages in adf and duplex adf. A
patch will take a while, because I only have sporadical access to a
MF6140 scanner.

Everytime the scanner reports an error on the lcd display, I need to
wait until scanimage ends, or faster I send a ^C to terminate scanimage.
However, I always need to reconnect the usb cable before scanimage can
start the next scan.

The status of this scanner still is untested.

Cheers,
Rolf
