Solving Problems
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 > General Settings > Fax Settings > Basic Settings > Line Type on the 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 header information for outgoing faxes is not registered.
Solutions
Select Settings > General 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.
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.
❏ When you send the fax in monochrome, enable Direct Send in Fax > Fax Settings > Fax Send
Settings.
