•If the printer is connected to a Digital Subscriber Line, then make sure you are using a DSL filter for the printer.

•If the printer is connected to a VoIP adapter or cable modem, then make sure that the printer is plugged into the first phone port.

•If you are using a splitter, then make sure that you are using a phone splitter. Do not use a line splitter.

Cannot send faxes

If the “Fax troubleshooting checklist” does not solve the problem, then try one or more of the following:

MAKE SURE THAT YOU HAVE REGISTERED YOUR USER INFORMATION IN THE PRINTER

If you did not enter your user information during initial setup, then enter your fax name and fax number. In some countries, you cannot send a fax without entering your fax name or company name. Some fax machines also block unknown faxes or faxes without sender information.

DECREASE THE TRANSMISSION SPEED OF THE FAX MODEM

The modem of the printer can transmit data at 33,600 bps. This is the maximum speed at which the printer can send and receive faxes. It is not necessary, however, to set the modem to its fastest transmission capability. The speed of the modem of the receiving fax machine must match or be greater than the speed at which you are sending your fax. Otherwise, your fax will not be received.

1From the printer control panel, navigate to:

> Setup > OK > Fax Setup > OK > Dialing and Sending > OK > Max Send Speed > OK

2Select a sending speed, and then press OK .

ENABLE ERROR CORRECTION

Errors and blurs may appear in the faxed document if there is too much noise on the line. This option enables the printer to transmit the bad blocks of data again and correct the errors. When a fax has too many errors, the fax may be rejected by the receiving fax machine.

1From the printer control panel, navigate to:

> Setup > OK > Fax Setup > OK > Dialing and Sending > OK > Error Correction > OK

2Check to see if error correction is set to On.

If it is not set to On, then press the arrow buttons to select On, and then press OK .
