How to test your fax machine
Follow these four simple steps to check if your fax machine is sending properly.
1. Prepare your test fax
Create a single-page or multi-page black & white test fax. The content is irrelevant, so feel free to be creative.
2. Send the test fax
Send your test fax to one of our test numbers from the fax machine or printer you wish to test.
3. Await fax arrival
Wait a minute or two for your fax to appear above.
4. Review your received fax
Check the orientation, quality, masked sender number and your sender ID.
FAQ: Common Questions About Our Fax Testing Service
Faxbeep is a free online service that lets you test your fax machine's sending capabilities. It provides test fax numbers in the US, UK, and Australia that you can send faxes to, and then view those faxes online within minutes.
Your faxed document becomes publicly visible on the website for 30 days before automatic removal. If you need your fax removed sooner, click "Request removal" on its detail page. We recommend not sending sensitive or confidential information through this test service.
If you've sent a fax that contains private or sensitive information, you can request its immediate removal. At the bottom of every fax detail page, you'll find a "Request removal" link. Click it and your fax will be promptly removed from the service.
