[sane-devel] Canon TR8520 will print but not scan

[Tim Schoell]

I am fairly new to Linux.  I"m running Ubuntu 20.04.  I can get you the 
hardware detail if you need, but you'll have to tell me how.

I have having trouble getting my new Canon TR8520 to scan.  It prints 
just fine, but I can't get my computer to recognize the scanner.  I've 
tried both WIFI, and directly connecting with a USB cable, and nothing.  
This is the version of the SANE backend I have installed:  scanimage 
(sane-backends) 1.0.25git; backend version 1.0.30

I've tried many ways to edit the pixma.conf file to manually enter the 
address of my scanner, but nothing works.  In fact, I get he following 
errors when I run scanimage -L:

[19:38:55.493124] [bjnp] udp_command: ERROR - no data received
[19:38:55.493269] [bjnp] bjnp_init_device_structure: Cannot read mac 
address, skipping this scanner
[19:39:07.504136] [bjnp] udp_command: ERROR - no data received
[19:39:07.504216] [bjnp] add_scanner: ERROR - Cannot read scanner make & 
model: bjnp://192.168.0.29

192.168.0.29 is the address I get from my printer for it's location.

Any help would be GREATLY appreciated.
