Oops!
It looks like VueScan couldn’t find your scanner Here are a few common problems people have connecting to their scanner. Make sure your scanner is plugged in and turned on before you start VueScan If you’re using a USB Scanner, try using a different USB cable or port. Old USB cables can often go bad
If you’re using a USB scanner, make sure your scanner appears in ‘About This Mac’ (in the Apple menu, then click ‘System Report’) in the USB devices section. If it doesn’t appear, you might try a different USB cable and/or a different USB port.
If you’re using a WiFi scanner, make sure your firewall and router aren’t blocking mDNS responses (UDP port 5353). Also, make sure you aren’t using a Virtual Private Network (VPN) because this will interfere with finding scanners on the network.
If you’re using a USB scanner, does it appear in the Device Manager?
Is there a yellow triangle with an exclamation point next to it? If so, what is the error message? Does it say it loaded the Hamrick Software Driver? If there are problems, you might try a different USB cable and/or a different USB port.
If you’re using a WiFi, make sure your firewall and router aren’t blocking mDNS responses (UDP port 5353). Also, make sure you aren’t using a Virtual Private Network (VPN) because this will interfere with finding scanners on the network.
If you installed VueScan from the .tgz file, read the README.txt file or install VueScan from the .deb or .rpm files here
If it’s connected with WiFi, make sure your firewall and router aren’t blocking mDNS responses (UDP port 5353) or Canon responses (UDP port 8610 and 8612). Also, make sure you aren’t using a Virtual Private Network (VPN) because this will interfere with finding scanners on the network.
