Cannot Send Faxes

Select PBX in Settings > Fax Settings > Basic Settings > Line Type on the printer's control panel.

If your phone system requires an external access code to get an outside line, register the access code to the printer, and enter # (hash) at the beginning of a fax number when sending.

Select Settings > Fax Settings > Basic Settings > Header and set up the header information. Some fax machines automatically reject incoming faxes that do not include header information.

Contact your telecommunication company to unblock your caller ID. Some phones or fax machines automatically reject anonymous calls.

Check that the recipient's number registered in your contacts list or that you entered directly using the keypad is correct. Or, check with the recipient that the fax number is correct.

Ask the recipient if the recipient's fax machine is ready to receive a fax.
