I've been using my Canon I-Sensys 8280 scanner wireless for a couple months and it worked fine, when I updated to 16.04 LTS it suddenly stopped working. It seems to be detected scanimage -L reports a couple of problems but ends up detecting my scanner
*[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://192.168.0.103*
*device `pixma:MF8200C_192.168.0.103' is a CANON Canon i-SENSYS MF8200C Series multi-function peripheral*
When I try to load the preview or to scan I get an I/O error message
*[bjnp] sanei_bjnp_write_bulk: ERROR - Scanner length of write confirmation = 0x0 bytes = 0, expected 4!!*
*[bjnp] sanei_bjnp_write_bulk: ERROR - Scanner length of write confirmation = 0x0 bytes = 0, expected 4!!*
*[bjnp] udp_command: ERROR - no data received (timeout = 500)*
I've updated the backends (scanimage (sane-backends) 1.0.26git; backend version 1.0.26)
Any idea what might be the problem and how to fix it? I'm pretty upset that it just stopped working, would not have upgraded if I had known since I have to use the scanner everyday, any help will be greatly appreciated.
