Cannot Send Faxes

The following causes can be considered.

The connection line is set to PSTN in a facility where a private branch exchange (PBX) is being used.

Solutions

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

Sending faxes without entering an access code in an environment in which a PBX is installed.

Solutions

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.

The recipient's fax number is wrong.

Solutions

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.

The recipient's fax machine is not ready to receive faxes.

Solutions

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

The data being sent is too large.

Solutions

You can send faxes at a smaller data size using one of the following methods.

The header information for outgoing faxes is not registered.

Solutions

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.

Your caller ID is blocked.

Solutions

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