@Fish72, Welcome to HP Support Community!

Check for poor line conditions and resend when conditions improve. If available, try sending the fax through another wall jack and make sure you are using the phone cord that shipped with the fax machine.

Also, refer to the document HP Printers and Fax Machines - Fax Error Code Descriptions for any help with fax issues.

Hope this helps! Keep me posted.
