The "Using Correct Type of Phone Cord with Fax" test failed

●Make sure you used the phone cord supplied in the box with the printer to connect to the telephone wall jack. One end of the phone cord should be connected to the port labeled 1-LINE on the back of the printer, and the other end to your telephone wall jack, as shown in the illustration.

2Use the phone cord supplied in the box with the printer to connect to the "1-LINE" port

If the phone cord that came with the printer is not long enough, you can use a longer 2-wire phone cord to extend the length. You can purchase the cord at an electronics store that carries phone accessories.

●Check the connection between the telephone wall jack and the printer to make sure the phone cord is secure.

●Make sure you use the phone cord that came with the printer. If you do not use the supplied phone cord to connect from the telephone wall jack to the printer, you might not be able to send or receive faxes. After you plug in the phone cord that came with the printer, run the fax test again.

●If you are using a phone splitter, this can cause faxing problems. (A splitter is a two-cord connector that plugs into a telephone wall jack.) Try removing the splitter and connecting the printer directly to the telephone wall jack.

The "Dial Tone Detection" test failed

●Other equipment, which uses the same phone line as the printer, might be causing the test to fail. To find out if other equipment is causing a problem, disconnect everything from the phone line, and then run the test again. If the Dial Tone Detection Test passes without the other equipment, then one or more pieces of the equipment is causing problems; try adding them back one at a time and rerunning the test each time, until you identify which piece of equipment is causing the problem.

●Try connecting a working phone and phone cord to the telephone wall jack that you are using for the printer and check for a dial tone. If you do not hear a dial tone, contact your telephone company and have them check the line.

●Make sure you have correctly connected the printer to the telephone wall jack. Using the phone cord supplied in the box with the printer, connect one end to your telephone wall jack, then connect the other end to the port labeled 1-LINE on the back of the printer.
