My HR department's fax machine is down, and I'm looking for a reliable test fax number to help troubleshoot the issue. The web interface for the Canon MF455dw says it's ready to send faxes, but when I try, it shows a TX Error report indicating busy or no signal. This has been going on for over a week. Any suggestions?

You might want to check with local businesses like libraries or real estate agents, as they often still have fax machines. They might allow you to send a test fax to see if it works!
Hey, it sounds like you're having a frustrating time. Sometimes the issue is with the receiving end, not just your machine. Have you tried sending faxes to various numbers to see if it’s an issue on their side?
There’s actually a quick solution! Canon has a free fax testing service. You can send a fax to 1-855-392-2666, and it will send back a test confirmation sheet. It's a great way to figure out if the problem is on your end or the receiver's.

Thanks! I’ll give that a try.
