Fax troubleshooting checklist

If you encounter problems sending and receiving faxes, then check the connection first:

1Check for a dial tone on the telephone line by plugging an analog telephone into the wall jack, DSL filter, VoIP device, or cable modem where you connected the printer. Make sure you plug the telephone into the same port.

If you do not hear a dial tone, then contact your line provider.

2While the printer is connected to the telephone line, check for a dial tone by plugging an analog telephone into the port of the printer.

If you do not hear a dial tone, then use the checklist below. Listen for a dial tone after checking each item.

If you hear a dial tone but still have problems sending and receiving faxes, then see the other topics in this section.

Connection checklist

Make sure that the printer and other devices on the line (if applicable) are set up and configured correctly according to your setup scenario.

Make sure that the cables are connected to the correct ports.

Make sure that the cables are securely plugged in.

Check the cable connections for the following hardware, if applicable:

Power supply Answering machine Cable modem Splitter

Telephone

VoIP adapter

DSL filter

RJ11 adapter

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

2Select a sending speed, and then press .
