My Brother MFC-J410W Scanner/Printer used to work fine with my MacBook Pro for both scanning and printing. Originally, the printer was detected automatically by OSX (Snow Leopard) with no special setup.
Recently, I am no longer able to scan, and I can print only by setting up the printer manually (using its IP address).
I'll appreciate any troubleshooting tips, specifically - how can I tell whether the problem is in the printer, in my Macbook or in the wireless router?
