officejet 5740 getting fax error 345 BUT receiving party receives the fax

[cimteltony]

Hi,

We are using an HP Officejet 5740 e-All-in-One Printer. We were trying to fax one specific long-distance number and kept getting result of "Error 345". After several attempts with the same error, we called the receiving party and they said the fax is coming through. What we don't understand is: "Why is this 5740 giving the error even though the faxes are going through?" We verified the 5740 firmware is current. Any help is appreciated.

Welcome to the HP Support Community.

I'd be happy to help.

Error 345 indicates 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.

A noise from call waiting service disrupted the call. Disable Error Correction Mode (ECM) if necessary.

Let me know if this helps.
