Solve fax problems

If you still have problems using fax after successfully completing the fax test on page 5, follow the steps below:

Cannot send but can receive faxes

To check that the wireless connection is working properly, print the wireless test report.

1.Perform a copy or scan to ensure that the printer is working properly.

2.Check the physical fax connections.

3.Check if other fax devices can send to the same phone number. The receiving fax device might have blocked your phone number, or it might be having technical problems.

4.If the problem persists, print the Fax Error Report and Fax Log (and if available, the caller ID report and junk fax report), and then contact HP for further help.

Cannot receive but can send faxes

1.Check the fax settings on the printer.

2.Check the physical fax connections.

3.Check if other devices connected to the same phone line can receive faxes. The phone line might be faulty or the sending fax device might be having problems sending faxes. You might also want to check if you have blocked the sender’s phone number.

4.Check the problem with the sender. If the problem persists, print the Fax Error Report and Fax Log (and if available, the caller ID report and junk fax report), and then contact HP for further help.

Cannot send and receive faxes

1.Perform a copy or scan to ensure that the printer is working properly.

2.Check the physical fax connections.

3.Check the fax settings on the printer.

4.Check if other devices connected to this phone line can send or receive faxes. There might be a problem with the phone line.

5.Reset the printer by turning off the printer and, if possible, the main switch of the power supply. Wait for a few seconds before turning on the power again. Try to send or receive a fax on the printer.

6.If the problem persists, print the Fax Error Report and Fax Log (and if available, the caller ID report and junk fax report), and then contact HP for further help.

If you have subscribed to a voicemail service on the same phone line used for faxing, you will have to receive faxes manually.

Check the printer fax settings

•• The Auto Answer feature is turned on for the printer to receive fax automatically.

•• If you have subscribed to a voicemail service from the phone company or service provider, ensure that the Rings to Answer on the printer is set to be more than that of the telephone answering machine. The printer will monitor the line and decide if an incoming call is a normal phone call or fax call. If it is a fax call, the printer will start a fax connection automatically. Otherwise, you might have to receive the fax manually by touching Fax.

•• If multiple phone numbers are assigned to the same physical phone line and the line is shared by multiple devices, ensure that the printer is set to the correct distinctive ring setting for receiving faxes.

Check the physical fax connections

•• Connect the phone cable from the port labeled 1-LINEon the back of the printer to the phone wall jack and connect a phone cable from the port labeled 2-EXTon the back of the printer to an extension phone. From the extension phone, call the phone number that failed to receive the faxes.

If you were trying to fax to an external number, be sure to include any required access code or num- bers prior to entering the number. You might also need to add a pause in the number to prevent the printer from dialing too fast; to add a pause, touch * repeatedly until a dash (-) appears on the display.

•• If you cannot make any outgoing calls because no dial tone is detected or the line is noisy, try using another phone cable in place of the one connected to the 1-LINE phone port, or move the printer to another location that has a separate phone line (if possible) and see if there are similar problems.

•• If you are in a digital phone environment (such as FoIP,

fax over VoIP), reduce the fax speed and turn off the Error Code Modulation (ECM) from the printer control panel. If needed, contact your phone company to find out if there are problems with the phone line or to learn more about the capabilities of the phone network.
