What does Error 350 mean on an HP OfficeJet Pro 8720

Hi,

Error Code 350 means the following:

Check for poor line conditions. Older phone lines, static on the line, power brownouts, or other power-related problems can cause communication failures. Call the telephone provider if line conditions fail to improve.
Stop key was pressed on the receiving fax machine before the fax completed. Contact the person receiving the fax to see if they are cancelling the transmission. If not, send the fax again but at a slower transmission speed.
Call waiting service made a click sound that is heard for an incoming call, momentarily disconnecting the fax call. Disable error correction mode (ECM) if necessary.

I suggest going to Fax and clicking the gear icon or Setup button, select Preferences and locate Error Correction Mode, then toggle the option Off and check for any difference.

If the same persists you should contact your Phone Service provider.
