Solve fax problems
This section contains fax setup troubleshooting information for the printer. If the printer is not set up correctly for
faxing, you might experience problems when sending faxes, receiving faxes, or both.
If you are having faxing problems, you can print a fax test report to check the status of the printer. The test fails if
the printer is not set up correctly for faxing. Perform this test after you have completed setting up the printer for
faxing. For more information, see
Test fax setup.
