My scanner used to work till yesterday. Now when I try to scan, document is on the scanner, click scan from the cannon quick menu (as before), and it wakes up the printer/scanner, and seems to start scanning. Then after several long minutes (longer than before), it gives me the error: 2,157,50.
I've restarted the printer several times, restarted the PC (OS- MS Vista), and restarted the network.
The printer prints fine, both airprint from iOS devices and the PC.
The scanner doesn't seem to work.
Solved! Go to Solution.
I downloaded the driver again, reiinstalled, didn't work.
I turned off firewall...and it works!
Now I have to disable the firewall every time I want to scan, but at least it works!
Go into your firewall settings and allow access to your Canon scanner software. May have been blocked due to an update!?!
