Unable to scan on a Brother MFC-L3770CDW Via AirPrint

I'm having the exact same issue with a Brother MFC-2750DW. I connect with AirPrint, and have followed all of your troubleshooting steps, and gotten the same results. My machine is hardwired to the network, and have always been able to print without interruption. The scan function is a total crapshoot. Image Capture works far more reliably than navigating through the Scan app in settings. And I have three frequent users who have this issue, but not at the same time.

Have you found a reliable solution?

Try using Preview and/or Image Capture to scan. If they can't see the scanner then you'll need to look into its wireless connectivity and follow the directions in this Apple document: Reset the Mac printing system to solve a problem - Apple Support

If all else fails give the demo version of VueScan a try. I use it to wirelessly scan with my Epson All-in-One unit.

Hello TrevorSeward,

It sounds like you've done some great troubleshooting. To get started, we recommend ensuring your scanner is set up correctly. You can learn how to do that here: Set up a scanner to use with Mac - Apple Support

These steps may help:

1. Before setting up your scanner, make sure macOS has the latest scanner software available to it. Check with your scanner’s manufacturer to see if any updates are available for your scanner model.

If you have a multifunction AirPrint printer and scanner, you don’t need to check for software updates.

2. Follow the instructions that came with the scanner to unpack it and connect it to your Mac.

If your Mac has a single USB-C port, and you want to connect a USB scanner, use a multiport adapter. Connect the scanner, then connect a USB-C cable to a power supply to prolong the battery life of your Mac. See Use USB-C cables with Mac.

Important: Don’t install software that came with the scanner. Your macOS computer downloads the latest scanner software automatically.

3. Choose Apple menu  > System Settings, then click Printers & Scanners  in the sidebar. (You may need to scroll down.)

4. If you don’t see your scanner in the Printers list, click the Add Printer, Scanner, or Fax button on the right.

5. Select your scanner, then click Add.

If your scanner isn’t in the list, see the documentation that came with the scanner to find out how to scan with it.

Thanks.

Thanks for reply back with that information, TrevorSeward. Since those steps posted haven't worked, and you already tested the issue in safe mode, the next recommendation would be to test your scanner in another user. Create a new test user profile with the same administrative rights. Log in to it, then see how the scanner works. This will rule out possible underlying causes with your user profile.

Then we can evaluate the report to see if we can determine the cause of the problem.

It will no longer work with the Scan option in settings. Were you able to use Image Capture in your Applications folder to initiate a scan? This is the way scanning is done when driver support is no longer available and the printer is capable to print via AirPrint.

Hello,

I solved a similar problem, that I had with an Epson scanner, by disabling the "Limit IP Address Tracking" option in the wifi config. If you this option on, try to disable it.
