Can't scan from Brother MFC-J470DW over WiFi connection

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.

So, after I saw the WinXP PC work properly, I ran the Brother Install Diagnostics on the Win7 PC. It said the scanner and printer driver were not installed. Odd, since it prints fine. It recommended to put the install CD in, and run Repair. I attempted that, and got to a point where you select a USB or Wireless connection. USB was selected, and it would not let me select Wireless. Doh! So I uninstalled the whole Brother package, rebooted, reinstalled from scratch, selecting Wireless when I had the opportunity, and then rebooting again. Yay, it still printed, but no CC4 control. I had NIS Smart Firewall enabled again, so turned that back off, and now the CC4 Remote Device Config saw the thing. Configured Smart Firewall to let the Brother stuff through, and now it's all working. Annoying, since on the XP PC, the Brother sw apparently setup NIS to allow it through. But it's all good now.

I'm going to split the points between Technodweeb, who got me going on the XP side of things with his ping recommendation, and Joe for his detailed Brother insight. Thanks guys!

Turn off the windows firewall from inside the control panel. Test it again.

That was a good thought. I'm using Norton Internet Security, so I turned off the Smart Firewall. Unfortunately, that had no effect on the problem.

here is another test... If you have another computer on the network, try pinging the IP address of the computer you are trying to get working. If you can ping it, then the firewall is indeed turned off, if you cannot ping it, you have more work to turn the firewall off. Norton plays some silly games in the firewall area. Even when uninstalled, it can still be active unless you use their uninstall tools.

I do not know if this will give us any good intel but before we stab at other things, lets make certain this is not an issue.

Also what is the IP address of the computer in question and the IP address of the MFC?
DwaineoAuthor Commented:
Yes, I have another PC on the network. I can ping the Win7 PC in question, with Smart Firewall disabled.

Win7 PC is
MFC-J470DW is

The Windows XP PC I pinged the Win7 PC from is

I'm in the process of installing the Brother CC4 software on the WinXP PC to see if it works from there. That PC is also setup to print on the MFC-J470DW, and does that properly.

Why does Win7 networking have to be such a pain?

The Brother CC4 software works fine on the XP machine, even with NIS Smart Firewall enabled. Scanning works, and Remote Setup works. I guess this proves there are no setup issues on the MFC-J470DW itself. And that it can do all this stuff over WiFi.

Now, if only it worked with the Win7 PC.

Hi Dwaine,
I have several Brother MFCs. My experience with them is that using a static IP address (which you said you're doing) and installing what they call the Full Driver & Software Package is the way to go. There has been a relatively recent update to the W7/64-bit package (Release Date 05/28/2013) for your model:

If you're not on that, give it a try. I've had great success in doing this with all of my Brother MFCs (although I don't have a J470DW). If that doesn't work, I'll recommend some other troubleshooting steps. Regards, Joe

One other thing – firmware. There has been an extremely recent update to that (Release Date 12/12/2013) for your model:

I've had some Brother MFC firmware updates fix serious issues in the past. Regards, Joe
Joe Winograd, Fellow&MVEDeveloperCommented:
Interesting stuff! Thanks for letting us know how it all played out. Very glad to hear all is good now. Regards, Joe

Joe and Technodweeb put me on the correct track to doing more detailed diagnosis on my end, and reinstalling the Brother software/driver package, and properly setting up the NIS Smart Firewall settings.
