HP Office Jet Pro 8600 all in one

Question

I fax documents from word with my printer. Every once in a while, but more frequently as of late, the document will fax, shows send in the log, I hear the the fax completely send and hang up, but then it will fax it over and over, even though I only set it to fax one time. Only way then to stop it from sending is to turn off printer and then I either have to reboot my computer or log off to get it to clear. When computer comes back up, I turn printer back on and it is ready for use. It has done this since I bought it, but like I said seems more frequent.
It is an HP office jet pro 8600 all in one, running on Windows 8.1. It is hard wired, not running wirelesslym with desktop. Anybody have any clues as to what is causing this and how to fix it.  It is so frustrating.  Thanks.

Hi LFoskey,
Does the printer send multiple faxes when you fax directly from the printer, or only when you fax from Word?
You can check for a firmware update in cause the issue is being caused by the printer itself;
HP Officejet Pro 8600 N911a Firmware
HP Officejet Pro 8600 N911g_n Firmware (Plus and Premium models)
Please also try the HP Print and Scan Doctor, it can quickly resolve any issues including but not limited to;
Driver Check : Checks for missing or corrupt driver files.
Device Manager : Checks for problems in Device Manager that would prevent printing.
Device Online : Checks if the product has been paused or set to offline, and then sets the status back to online if necessary.
Print Queue : Checks for and clears pending print jobs in the print queue (a log of print jobs waiting to print).
Port Match : Checks the port settings for the HP product.
Device Conflicts : Checks for conflicts with other drivers, such as other printer brands.

Please post back and let me know if there are any symbols other than green check marks and what they are next to of course. The wrench is not always easy to spot as the wrench and the check mart are in the green circle. 
If you see only green check marks ( ), the tool did not find any problems.
If you see green wrenches ( ), the utility identified an issue and corrected it automatically.
If you see yellow exclamation points ( ), the test failed and required user action, but the step was skipped.

I look forward to hearing from you. Thanks.
