[sane-devel] Canon ImageCLASS MF743cdw

[Chris Richards]

Greetings all, 

I just bought this AIO Canon.  It has both USB and Network, and I have
it on the network.  So far it's been doing what I need, but I have to
use a Windows VM to talk to the scanner.  I've captured network packets
when using the windows VM, and it appears to be using ports 8510/8512. 
If I use the SANE Pixma configuration file to talk to it, I can see it
sending packets over the network to the printer, but it fails to ID the
printer. 

The Windows INF file seems to indicate driver support for the following:


"Canon MF745/746"=MF746C_USB,USB\VID_04A9&PID_27FA&MI_00
"Canon MF742/744"=MF742C_USB,USB\VID_04A9&PID_27FB&MI_00
"Canon MF741/743"=MF741C_USB,USB\VID_04A9&PID_27FC&MI_00
"Canon MF645"=MF645C_USB,USB\VID_04A9&PID_27FD&MI_00
"Canon MF642/643/644"=MF642C_USB,USB\VID_04A9&PID_27FE&MI_00
"Canon MF641"=MF641C_USB,USB\VID_04A9&PID_27FF&MI_00
"Canon MF745"=MF745C_USB,USB\VID_04A9&PID_2800&MI_00
"Canon MF642/644"=MF644C_USB,USB\VID_04A9&PID_2801&MI_00
"Canon MF Scan"=MFSCN_NW,CANON_MFNP&MFSCN
"Canon MF745/746"=MF746C_NW,CANON_MFNP&MF746C
"Canon MF742/744"=MF742C_NW,CANON_MFNP&MF742C
"Canon MF741/743"=MF741C_NW,CANON_MFNP&MF741C
"Canon MF645"=MF645C_NW,CANON_MFNP&MF645C
"Canon MF642/643/644"=MF642C_NW,CANON_MFNP&MF642C
"Canon MF641"=MF641C_NW,CANON_MFNP&MF641C
"Canon MF745"=MF745C_NW,CANON_MFNP&MF745C
"Canon MF642/644"=MF644C_NW,CANON_MFNP&MF644C 

When I plug the printer in via USB and run sane-find-scanner, it gives
me the following:

<trying to find out which USB chip is used>
could not claim USB device interface
found USB scanner (vendor=0x04a9 [Canon], product=0x27fc [MF741C/743C])
at libusb:003:008 

I dunno if any of this is helpful, but if anyone cares to take a stab at
this, I'm willing to test. 

Thanks in advance.
