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.
If the test fails, review the report for information on how to fix any problems found. For
more information, see The fax test failed.
