I have a splitter out of the back of my Ooma Telo; one line goes to a DECT phone base and another to the fax line of an HP OfficeJet 6500. Within the last month, I have suddenly lost the capability to fax on the 6500 via Ooma. In terms of troubleshooting, I turned ECM off, decreased the transmission rate to 9600, tried new phone cords, and ensured that faxing is enabled via My Ooma. My ISP is Comcast.
When I do attempt a fax, the 6500 dialer calls out (using *99) and I can see the recipient fax machine name on the 6500 screen. The document handler feeds the document and it appears that the fax went through, but I always get a "failed transmission" message that indiates "Error 345."
Has anyone else encountered this problem or something similair?
If you are using an Ooma Telo try using *98 followed by a pause.
HP Error Codes: 344, 345, 346, 347, 348, 349 ECM, 350 ECM, 351 ECM, 352 ECM, 353 ECM, 354, 355
•The remote machine failed to respond to a fax command from the local machine because the connection was interrupted. These errors can occur if the phone lines in the area to be faxed are old or there is noise (static on the phone line). Other reasons can include power outages and other power-related problems.
•The call-waiting service can cause this error. The click, heard for an incoming call, is actually a momentary disconnect of the line.
•The remote user pressed the Stop key while the reception was in progress.
•Under rare conditions, incompatibility between the two machines might cause the remote machine to abandon the call.
•Retryt the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
•Disable ECM. Errors might still occur, and might result in a degraded image quality on the received page. However, the ability to send the entire document will be improved. Click here for instructions on enabling and disabling ECM (c00060802) (in English).
•Try sending at a lower transmission speed.
