Hp Office Jet Pro 8600 A910, suddenly can't send fax. Reveiving faxes are ok.

Question

We can't send any fax, but we can still receive a fax. This happened suddenly without any changes (on device or our telephone line) When sending a fax it dials and gives a busy tone. After that we get a error sheet pointing out Error 388, communication error. Following things we did:- Tried sending fax on our other phone line to rule out broken phone cable/connections.- Called to phone and from phone to fax which worked.- Printed out T90 testsheet. All tests passed.- Tried faxing with ECM off or in other words turned off the error connection mode.- Tried faxing with lower connection speed setting.- Checked other settings to see if there was anything wrong, but all okay.- Powered off, disconnected power cable for at least 15 seconds. Is the fax broken or anything else we can try?

Hi , I see you have been troubleshooting an issue with your Officejet Pro 8600 no longer able to send faxes, and I think I may have found some more information for you. Can you specify your your exact printer model for me? In your post title you say it is an 'Office Jet Pro 8600 A910' but and A910 is an Officejet 8500A. How Do I Find My Model Number or Product Number? Seems like an odd question, but the printer make a copy? It could be an issue with the scanner mechanism.
 Is the printer connected directly to a wall outlet or is it in a surge protector or a power bar? We want to connect it to a wall outlet just so we can eliminate the power source as the root cause. See this document for more information about Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector (Note: This document is not limited to Laserjet printers.)
 HP regularly releases firmware updates that may also correct the problem you are experiencing.

It's usually located in the setup menu, under tools. The fax test report will let you know if it finds any problems and how to correct them. Once everything passes on the fax test report, you can Test Your HP Fax Machine with the HP Fax Test Service.  I reviewed the error code you provided from the Interpreting Error Codes in Fax Communication Error or Fax History Reports document.  Error 388: There is too much noise on the line for a valid connection between two fax machines to complete. The noise problem might go away over time. Retry the fax reception when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve. Have you touched base with the phone company to make sure they have not changed anything on their end? Does this same error occur with every number you try to dial?  You could see if anything in Fax Sending Fails Intermittently or Fails for Only One Recipient is helpful as well.  Please let me know if these steps resolved your issue, or if there is anything else I can do to help.  I look forward to hearing from you!   Thanks,
