Hi greenplanet,
Thank you for using the Support Forum. Please take a look at the solutions for unable to receive faxes and see if any of these solutions help with your situation. If not please consider contacting your support centre for further assistance.
Using faxtoy.net, I can confirm that the fax can send because the paper that I fax out appears on that website.
When receiving, I was using faxzero.com to send documents and although I receive confirmation from that website that the fax was successful but I never recieved anything.
How can I fix it? Do I have to change some settings on the Xerox Phaser 6128MFP?
