I have a Brother MFC-J470DW multifunction scanner/printer/fax. It's connected to my Win7 Pro 64 bit PC via Wifi, using Infrasturcture mode, with a fixed IP.
It's configured in my Windows Printer setup properly, and I can print to it with no problem.
But when I open the Brother Control Center 4 app, and select Scan, it says:
MFC-J470DW cannot be found
If I go into CC4 Device Settings / Remote Setup, I get a similar message.
If I go into CC4 Device Settings / BRAdmin, it opens the BRAdmin Lite app, and it sees the device at it's proper IP address. If the device is in Sleep mode, BRAdmin shows that. If I wake it up, BRAdmin shows the device is Ready.
I've been through the Brother FAQs and web site troubleshooting, and don't find a solution for this scenario, so I'm trying here.
