Firewall blocking scanner

I have an HP Officejet 7610 All-In-One printer and when I turn off the firewall I can scan. With the firewall on I cannot scan. How do I tell the Firewall to allow the scanner?

Connect it with a wire, do not use it wireless is a option that will work.

If you want to use it wireless, check the firewall log file and see what is block that the printer needs and set a rule for it.

My firewall log is empty.

To be clear, I am using Avast Internet Security. When I go to Menu, Tools, Firewall, Logs, There is nothing under "Blocked Traffic.
Under Rules I see a blocked IP Address for Port Scan Detection. How do I make a rule to allow it?
