I have a Brother MFC-665W. It is on a LAN using DHCP. I want to scan, and when i pushed the Scan button the LCD on the printer says "Check Connection". I can print to the printer, copy, and fax from it, but it doesn't want to scan. I've tried to scan from a PC using the Control Center 3, but when i try a prescan it gives me a Failed to Connect to device message. I've also tried setting static and clearing memory from unplugging the power, while press and hold the red stop button turned plugged back the power, but still the same have the same issue.
I think I solve the issue for scanning so far. Here's what you do goto control panel -> Scanners and Cameras. Then right click into propertise, then check Specify your machine by address. It should already have the printer IP address listed in the box below. If not our can goto to your router and see the ip in the DHCP Client List .
After this I'm able to use the Control Center 3 scanning.
I think the problem was the NODE name list in the setting in my winxp pro does not match the actual NODE name the printer is using.
