Image Capture has wrong IP address for scanner
I'm on Catalina 10.15.7. My Epson AIO WP-4530 has worked with this computer for years without fail. Today, though, Image Capture could not make a "connection" to the scanner. I noticed in Image Capture that it was looking for the scanner at 192.168.1.98, but the correct IP address is 192.168.1.97. There's no way to change that in Image Capture. The printer component was working normally. I opened the setup page on the printer (by directing Safari to the correct IP address) and found that the IP address listed there for Bonjour was, the incorrect one, although the printer, itself, said its IP was correct, 192.168.1.97. I changed the IP for Bonjour, saved, and exited.
Image capture still listed the scanner address as 192.168.1.98 and still could not connect to it.
I installed another instance of the printer/scanner using Epson Printer Finder, made the second instance active, and Image Capture then found the scanner instantly and scanned normally.
I deleted this new instance of the printer, went back to the original instance in Settings/Printers & Scanners, and tried Image Capture again. It still works, but it still lists the incorrect IP for the scanner.
So weird, I still don't know why the glitch occurred or why this process solved the problem or if IC listing an invalid IP address for the only scanner it finds is a potential problem. Just thought I'd post it here, in case someone else finds the experience useful.
