My Firewall is Blocking Printer/Scanner

Hi,

Thank you for writing to Microsoft Community Forums.

I understand that you have issue scanning images.

It would be great if you can answer these questions to assist you in a better way.

·         What is the make and model of the scanner?

·         What happens when you try to scan?

·         Are you using Windows Defender firewall or any other security software?

·         Are you aware of any changes made to the computer recently?

Meanwhile, you can try the following steps and check.

Thank you for your reply!

It says on the printer that it is a Canon TS5050, although it is listed on my computer as a TS5000.

When I try to scan, an error message pops up and the scanner does nothing. I have reinstalled Windows on my computer, to no effect.

I have Windows Defender Firewall and Avira Antivirus in operation. I tried turning off my firewall, or resetting it to default, but the scanner still would not work. This would suggest it is not a firewall-related issue, but I'm not sure. I also tried to play around with outbound rules, which didn't help either.

In terms of changes made to the computer: I recently was using Nox and Bluestacks emulators and turned off my firewall to do so. I may have accidentally changed something while doing that.

I would appreciate any help you could offer. Thanks

Hi,

Thanks for replying.

• When you say “When I try to scan, an error message pops up”, what’s the complete error message that you receive?

• How is the printer/scanner connected to the PC?

  e.g. wired/wireless

Meanwhile, I suggest you refer and follow the suggestion from the article on Scanner Does Not Work and Scanning Problems and see if that helps.
