Running a Fax Test from Your Printer's Control Panel - HP LaserJet Pro M1212nf Multifunction Printer

This video shows how to run a fax test from your printer's control panel.
You would want to run a fax test if you are having problems sending or receiving faxes.
A fax test can also help you to verify that your fax machine is working properly,
and that its connections are set up correctly.
Before you run the fax test, load plain, white paper into your printer.
Next, press the Setup button (which looks like a wrench) on the printer's control
panel.
Use the arrow buttons to select Service, and then press the OK button.
Use the arrow buttons again to select Run Fax Test, and press OK.
Press OK again to begin the test.
The printer will check the faxing hardware and the phone connections.
After the test is complete, a report prints, which details the results of the test.
Follow the tips or troubleshooting steps on the printout to help resolve any fax issues
that are found.
