I have a Brother MFC-2740DW that I have been using for many years. For over a year I have had it connected to the local network via wifi. It has a scanner function, which I normally use via the Printer application on my Mac. Today the scanner function is no longer present.
I found some advice online to reset the print system, which involves deleting the printers in the Printers and Scanners preferences app, then re-adding them back. I tried that, and still there is no scanner function.
When accessing the app, the dialog now looks like this:
This looks different from how it looked previously. But at the top right there appears to be a printer icon and a fax icon, but no scanner icon. Clicking on any of these icons show nothing.
I can access the website built into the printer driver, and for scanning it only shows the option to scan to FTP, which is not what I want.
The printer control panel has a scan option, but when using it and attempting to scan to a file (or any other option) it just says "Check Connection".
The printer still prints normally, which tells me that the wifi connection is working. Rebooting the Mac or power cycling the printer does not help.
I am wondering if this can be fixed.
I temporarily accepted an answer because the scan function appeared to have been restored. The scanner apps looks just like it used to. However, when I tried a scan, I get "Scanner reported an error" and "an error occurred while communicating with the scanner." So I am not out of the woods yet!
Because of those error message decided to reboot the Mac. After that, the scanning is connecting up, and scanning is working.
So again selecting the first answer to come in.
I don't scan very often. But over the last couple of years, every time I try to use the scanner function, the scanner icon is dimmed out. Rebooting printer and computer sometimes helps, but usually I have to reinstall the scanner driver, as described in my answer below.
Sometimes the scanner icon is not even present.
Is there some fix other than reinstalling the driver every time?
