My Epson sx430 keeps going offline, I reinstall it and its ok for a short time, then goes offline again. Any ideas?
The problem is the IP address has changed.
And the definition was fixed - hard-coded - in the printer driver!
Yes, that's Epson's fault.
You'll need to be using an account with Admin rights to fix it.
Quick fix:
1. On the printer, use setup/tools.
2. Find the IP address (you probably only need the 4th number).
3. On your computer, find your printer and then its properties.
4. Then find the printer port. You need to reconfigure it.
5. Change the IP address (4th number) to match what you found on the printer.
6. Note: the port will still have the same (wrong) name, but the right IP underneath
7. This will work until something changes on your router, e.g. a new tablet connects.
Long term fix:
8. On your router, assign a fixed IP address to your printer if you can.
9. Make it well out of the way of DHCP range (e.g. add 100 to the 4th number).
10. You could turn DHCP off but that might cause other issues.
Best fix:
10. Epson to make sure their printers can cope with the decades-old DHCP protocol.
