Epson printer message: "DNS error. Check DNS settings."
Quick answer
While scanning to a shared network folder, the printer could not resolve the destination computer's network address via DNS. Epson recommends using a static IP address in the destination path instead of a computer name, and verifying DNS settings on the printer, server, and network.
Before you try the solution
- 1. Copy the complete message exactly as shown, including any code, letters, or punctuation the panel puts around it.
- 2. Find the printer's exact model number. The same-looking code can mean something different on another model family.
- 3. Let the current print, scan, or update operation stop before touching controls, paper paths, or covers.
