A Simple Way to Test a Fax Machine

Generally when I've had to test a fax machine connection I've had to call a friend up in an office somewhere and we send test faxes back and forth to make sure my fax machine is working in both directions.

Recently I've found this harder since fewer people I know are using fax machines and often the problem comes up on weekends and late at night when it's hard to reach a friend.

HP offers a test faxback service for this purpose that can be used at any time all by yourself:

It lets you fax the service and get a response in a few minutes.
