Hi Oreo60,

I see you are getting a 346 error code when faxing with your HP Officejet Pro 8600 (N911) series printer.  Please take a look through the document linked below.

Interpreting Error Codes in Fax Communication Error or Fax History Reports

Error Code: 344, 345, 346, 347, 348, 349 ECM, 350 ECM, 351 ECM, 352 ECM, 353 ECM, 354, 355

Definitions 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. Solutions 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. Try sending at a lower transmission speed.

Hello,

Can you successfully fax to another fax number? Can you receive faxes?

You can test this by sending a fax to 888-HP-FAXME  It will send you a return fax after several minutes. 

This error code is caused by:

• 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.

I have tried diabling the ECM.  I have also set a fax to your test fax and it came back ok.  Could it be the fax number to where I am sending it?  I have tried 2 numbers there several times.  How do I slow the transmission down? I haven't tried that yet.  Could it be because I am using a Mac now?  I have never had this problem before.

If you have sent a fax to the HPFaxMe server and received an response, then the fax system is working with the 8600.  Most likely the issue is with the individual location you are attempting to fax.  It could be due to line condition, line traffic, etc; thus I would advise attempting to fax this number again at a later time and try contacting the receiver to make sure nothing is going on at their end.

As to lowering fax speed on an 8600:

• From the home screen press the Right Arrow
• Select the Setup menu
• Select the Fax submenu
• Scroll down and select Advanced Fax Setup
• Scroll down to Fax Speed and set the speed to Slow (9600)

CHANGING THE SPEED WORKS.  THANKS
