Fax error 346 is a common issue encountered when trying to send a fax. This error occurs when the receiving fax machine fails to answer the call or when the line is too noisy for the fax signal to be properly transmitted. To resolve this error, you can try to resend the fax at a different time when the line may be less busy or use an alternative method of sending the document, such as email. It's important to ensure that the fax number is entered correctly and to verify that the receiving fax machine is functioning properly. URL-https://printersofflines.com/b....log-post/hp-fax-erro
