Solving Problems
Connected to a DSL phone line without DSL filter.
Solutions
To connect to a DSL phone line, you need to use a DSL modem equipped with a built-in DSL filter, or
install a separate DSL filter to the line. Contact your DSL provider.

There are some problems in the DSL filter when you connect to a DSL phone line.
Solutions
If you can not send or receive fax, connect the printer directly to a telephone wall jack to see if the printer
can send a fax. If it works, the problem may be caused by the DSL filter. Contact your DSL provider.
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.
