Epson printer message: "No dial tone is detected."
Quick answer
The printer's fax function could not detect a dial tone on the connected phone line, so faxes cannot be sent. Epson recommends checking the phone cable, or disabling Dial Tone Detection when the printer is behind a PBX system.
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.

Other Epson error codes
- No paper has been loaded that matches the paper size setting.None of the loaded paper sources contain paper matching the size configured for the print job, so the printer cannot proceed until matching paper is loaded.
- An error occurred while saving. Check and if necessary, change the memory device.The printer could not write scanned or stored data to the inserted external storage device, which may be damaged, full, or unsupported. The user should inspect or swap the memory device.
- An ink cartridge is installed incorrectly.One or more cartridges are not fully seated in their bays. The user must press down firmly on each cartridge to ensure a proper connection.
- A printer's ink pad is nearing the end of its service lifeThe internal ink pads are close to saturation. Printing continues, and the message repeats until the pads are replaced. Epson directs owners to Epson support rather than describing a user replacement.
