Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Check where the phone line, the line or cable from your phone service that is... check where the phone line is plugged in.
On the Epson, it should be plugged into 'LINE' or the 'L' jack on the Epson. Not into the 'Phone' or 'P' jack or 'handset logo' jack.
How does it work once that is corrected?
OK. Your phone line may be lacking a dial tone now. Or the Epson might be 'broken'. The phone tech is a wise decision at this point, probably.
