That codes says:

"Redial count over with no response
or busy tone was not detected.
U.S.A. and Canadian models
will redial only once if a busy
tone is not detected."

The number you're dialing was first busy. When it went to redial, it detected no phone signal on the other end. If it happens to only 1 or 2 customers, then it's something to do with their lines and you can't fix that.
If it happens often, then get your phone lines checked out by your phone company, make sure your fax is not sharing the line with another other device and make sure it is not a digital line.
Other than that, you're looking at having to replace the main board in the fax. Which basically means it's time for a new fax machine.

DX-800 beeps with Incomplete Info Code = 720

Error Code 720: Cannot connect to the Pop Server. (Incorrect Pop Server IP Address) Pop Server is down.

Solution: Check the Pop Server IP Address. Contact the network Administrator

Regarding the beeping noises. The DX-800 has multiple settings for beeps, rings and the dialing monitor. If it is the latter, press MONITOR button once, then press the DOWN arrow, until silenced. Some ringer/beep settings are under Fax Parameters, some are in a special SERVICE MODE.

let us know if you can isolate which one and we can help turn it off. At least now you know what the 720 code means.

Good Luck!

Code 721 keep coming up and the machine keeps beeping. How do we fix it?

Error 721: Cannot connect to the Pop Server. (Incorrect POP Server IP Address) Pop Server is down.

Solution: Check the Pop Server IP Address. Contact the Network Administrator

Were you setting up email by chance, you need to make sure the email server settings are set correctly for your POP email provider. Otherwise you will get this message. If you don't use email, go into settings (Fax Parameters) and disable email features.
