How can I check the dial tone?

Faxing

A dial tone lets you know if the telephone line is working or if the printer is properly connected to the telephone line. If you encounter problems sending and receiving faxes, then make sure you can hear a dial tone on the line and through the printer.

Make sure the telephone line and the wall jack are working

1Plug an analog telephone into the wall jack.

2Listen for a dial tone through the telephone handset.

If you hear a dial tone, then the telephone line and the wall jack are working.

If you do not hear a dial tone, plug the analog telephone into a second wall jack, and then listen for a dial tone. If you hear a dial tone, then the telephone line is working but the first wall jack is not working.

Make sure the printer is connected properly to the telephone line

1While the printer is connected to a telephone line through the port on the back of the printer, plug an analog telephone into the port of the printer.

2Listen for a dial tone.

If you hear a dial tone, then the telephone line is working and properly connected to the printer.

If you do not hear a dial tone through both the wall jack and the printer, then see the “Fax troubleshooting checklist” on page 156.

How do I adjust the speaker volume on the printer?

Listen to the dial tone to check if the telephone line is working and to check if the cables and devices are connected properly in your telephone network. If you set the printer to receive faxes manually, then make sure that you set the ringer volume loud enough for you to hear it.
