Fax error messages on the printer control panel Error Message: Remote Fax Error Fax Mode Unsupported What it indicates: Possible solutions: The receiving fax machine cannot receive the fax. The error on the receiving end could be due to several factors. • Resend the fax. There may have been a problem with the quality of the connection. • Decrease the transmission speed of your fax modem. • Register your user information. In some countries, you cannot send a fax without registering your fax name and fax number. Some fax machines also block faxes without sender information. The receiving fax machine does not support color fax or the scan resolution of the document that you are sending. • Enable Auto Fax Conversion. The printer automatically converts color faxes to black and lowers the scan resolution of the document. • Lower the fax quality. • Reformat the document on Letter‑size paper.
