I have a Windows 7 PC and am having some issues getting the HP CM1312nfi mfp to Scan to PC. The PC has AVG Internet Security running as a firewall. I am assuming I need to make an exception in the Firewall but I am not sure what apps are required. I can print and scan from the PC. I have installed the ToolboxFX software as per HP's instructions but when I go to scan to a PC from the MFP I get an error that says this function isn't configured. Great HP.
