Hi SANE developers,

I'am trying to scan from a Canon MF623Cn which is a AIO device
from Canon's i-SENSYS MF620 series.

I'am a bit confused by the naming 'i-SENSYS' and 'PIXMA' from
SANE's POV. What is the difference (or is there a difference)
between i-SENSYS and PIXMA? Especially, can we use the bjnp
protocol (bjnp://myscanner.my.domain:8612) for Canon's i-SENSYS
devices when connected via IP?

The device is connected via IP and I added device's URL
(bjnp:// to 


But this results in:

 $ sudo scanimage -v -L
 [bjnp] udp_command: ERROR - no data received (timeout = 1000)
 [bjnp] bjnp_init_device_structure: Cannot read mac address, skipping this scanner
 [bjnp] udp_command: ERROR - no data received (timeout = 1000)
 [bjnp] add_scanner: ERROR - Cannot read scanner make & model: bjnp://

I am grateful for any help / Thanks
