MFC-665CW Scanner keeps saying Connection Failed

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.

    Yep it's hard to scan over the network, or even to a local storage like memory card

    I have the same problem. I used to be able to use the scan button to scan and now it says connection failed. It doesn't matter if I shut firewalls off or not.

    Has anyone solved this problem? Please post back here.

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.

I have a brother mfc-490cw and was having this same troubling issue. I have mine connected with the LAN. What I did to get it working again was press the MENU button. Then I went under the NETWORK item. On my machine there is a factory reset choice. I selected YES to the factory reset and then also selected YES to rebooting and when it came back up I was once again able to SCAN.

Hope this can fix your issue.

Make sure you IP address in the printer settings matches the IP address with the settings in your computer. If you hit (on the actual printer)
Menu using the arrow keys go down to LAN hit OK with the arrows keys go down to WLAN (for wireless) hit OK (TCIP should be highlighted )hit OK again You will see the IP address...copy it down somewhere
THen go into your computer Control Panel Printers/faxes double click on printers and faxes find Brother printer Right click and select properties Select ports CONFIGURE your PORT name OR IP address slot should match the one you took of the printer. CLick ok...
that should work...Hope it helps someone!

I used to be able to scan without issue, but experienced this same problem today. The printer showed as offline in my system tray even though it was not. I checked the Brother support site and saw that there was a new firmware update issued on 3/26/09, so I downloaded the update and installed it.

During the process, the printer beeped repeatedly as the firmware update was happening, and at the end of the update the system tray suddenly showed that the printer was now online. I can now scan from the Control Center, though as of right now if I try to scan by pushing the scan button on the printer itself I am still getting the "Check Connection" message.

So, it's not completely fixed but I am able to scan without issue from the Control Center interface.

How do i scan? using a brother MFC 685-cw..can't seem to use the scanner.. anyone help?

I have a Brother MFC 7840W and have struggled with the wireless features. Not sure how you have this configured but if wireless suggest you find a way to connect via LAN or USB...I cannot make mine work via wireless but hardwired works fine. To fix, I had to 'reset' the MFC (functions on the MFC itself) and then reinstall the software selecting USB as the connection method. Sounds crazy but once I did it worked.

Brother MFC 665CW can no longer scan since networked

That's rather normal, if your printer doesn't have scan-to-email functionality, you won't be able to scan unless you connect it via USB to a selected machine.

Brother printer/scanner - need to scan multiple pages to one doc

I suspect the scanner is not saving in .pdf format. Generally, if it scans to .tif files each page is in it's own file --- I know that can be very annoying.

Please change the scanner to save as .pdf using the following instructions:

Please let me know if this has been helpful or if you'd like any further assistance. Thank you.

Scanner - MFC 7420

Get the manual, and you may need the install disk too. Look carefully at the usb port on the copier so you get the correct usb cord.

Will not scan

This was on the Brother web site..

I cannot scan after installing the scanner driver using Windows®/ Mac OS® 8.x-9.x.
Description: Please follow the instructions below

Turn off your machine, disconnect and then reconnect the USB cable to your computer.
  1. Start "Device Selector" by double clicking "Device" in //Library/Printers/Brother/Utilities/Device Selector folder, or by clicking " Model" on the upper-left corner of the Brother Control Center 2.0 and selecting "other".
  2. Select USB as the connection type. Your machine name will appear on the list. Select your machine and click OK
  3. Close the Device Selector
  4. Open your scanning application and test.

Guess it's a long shot.. Hope it helps.

MFC-440CN: Prints but does not scan

Go to system/computer control panel, select "scanners and cameras". you should see your brother system in there (if u were able to print to it but not scan). Right click on it, select properties, and select "Network Properties" Tab. Choose select "specify your machine by address" rather by "by name". Most home/home office users dont have a local domain server at home, so even though your printer was named, it cannot be located by tcp-ip using the name, but rather by ipaddress. This solves the issue.
