I'm a major beginner with networks and all of this, and the way to get this scanner to function is beyond me.
This is the error readout after attempting to add the device directly to the pixma backend config file. It's the only reaction I've gotten trying to connect over wifi. Without listing the device in the config file, both sane-find-scanner and scanimage -L run (both run as root) show nothing. Error message below: [bjnp] udp_command: ERROR - no data received (timeout = 5000) [bjnp] bjnp_init_device_structure: Cannot read mac address, skipping this scanner [bjnp] udp_command: ERROR - no data received (timeout = 5000) [bjnp] add_scanner: ERROR - Cannot read scanner make & model: bjnp:// 192.168.68.110:8612/timeout=5000 Meanwhile, when connected by usb I get this readout in response to running sane-find-scanner, which lists codes that correspond to what's listed on the backend supported device charts for this printer/scanner model. Can't parse what the "Pipe error" bit means. Feedback message below: found USB scanner (vendor=0x04a9 [Canon], product=0x1854 [TR4500 series]) at libusb:001:005 could not fetch string descriptor: Pipe error # Your USB scanner was (probably) detected. It may or may not be supported by # SANE. Try scanimage -L and read the backend's manpage. Any guidance on how to get it working would be greatly appreciated. Thank you!
