Patricia’s HP printer, which I used to use to scan, has died (don’t know if it’s a bad power supply, or it’s just bricked). My Brother DCP-L2540DW laser, which is a great printer, refuses to scan. I can see it with Simple Scan, but I get a message that it cannot connect to the scanner. I went to the Brother web site, and installed their own drivers from rpm (actually from a bash script), and still no joy. A Google search indicates that others have had similar issues, but none exactly like mine (for instance, they can’t print, either, whereas the printer works fine). Any suggestions for trouble shooting?
