Fax issues
Run the fax test report rst to see if there is a problem with your fax setup. If the test passes and you are still
having problems faxing, check the fax settings listed in the report to verify that the settings are correct.
Run the fax test
You can test your fax setup to check the status of the printer and to make sure it is set up correctly for faxing.
Perform this test only after you have completed fax setup on the printer. The test does the following:
● Tests the fax hardware
● Veries that the correct type of phone cord is connected to the printer
● Checks that the phone cord is plugged into the correct port
● Checks for a dial tone
● Tests the status of your phone line connection
● Checks for an active phone line
To test fax setup via the printer control panel
1. Set up the printer for faxing according to your particular home or oice setup instructions.
2. Make sure the cartridges are installed and that full-size paper is loaded in the input tray before starting
the test.
3. On the Fax screen, ick to the right and touch Setup , touch Setup Wizard, and then follow the onscreen
instructions.
The printer displays the status of the test on the display and prints a report.
4. Review the report.
● If the fax test failed, review the solutions below.
● If the fax test passed and you are still having problems faxing, verify that the fax settings listed in
the report are correct. You can also use HP's online troubleshooting wizard.

● Turn the printer o by pressing (the Power button) located on the front left side of the printer and
then unplug the power cord from the back of the printer. After a few seconds, plug the power cord in
again, and then turn the power on. Run the test again. If the test fails again, continue reviewing the
troubleshooting information in this section.
● Try to send or receive a test fax. If you can send or receive a fax successfully, there might not be
a problem.
● If you are running the test from the Fax Setup Wizard (Windows) or HP Utility (OS X), make sure the
printer is not busy completing another task, such as receiving a fax or making a copy. Check the display
for a message indicating that the printer is busy. If it is busy, wait until it is nished and in the idle state
before running the test.
