The "Fax Hardware Test" failed

Solution:

•Turn off the device by using the Power button located on the device control panel and then unplug the power cord from the back of the device. 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 Fax Setup Utility (Mac OS), make sure the device is not busy completing another task, such as receiving a fax or making a copy. Check the display for a message indicating that the device is busy. If it is busy, wait until it is finished and in the idle state before running the test.

•Make sure you use the phone cord that came with the device. If you do not use the supplied phone cord to connect from the telephone wall jack to the device, you might not be able to send or receive faxes. After you plug in the phone cord that came with the device, 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 device directly to the telephone wall jack.

After you resolve any problems found, run the fax test again to make sure it passes and the device is ready for faxing. If the Fax Hardware Test continues to fail and you experience problems faxing, contact HP Support. Go to www.hp.com/ support. If prompted, choose your country/region, and then click Contact HP for information on calling for technical support.
