My HP 2610 defalt has changed to fax instead of print mode

Without doing anything to my knowledge, my printer now automatically has moved to a 2600 series fax mode instead of the 2600 series print mode that I have been using since I purchased it three years. When I click on print anywhere, HP Photosmart 2600 series fax shows up on the name line. Next to the icon of the machine is a black circle with a white check mark in it. The same circle and check mark appear in printer information in my computer's control panel. I read the owner's manual and followed the instructions to reset the factory defaults. When I reset the defaults, the printer mode I have been using for years is restored, but only for the document that is open and ready to print. When I want to print another document, the fax mode has returned. How can I restore my normal print mode? It is annoying to have to manually change the mode each time. Your assistance will be greatly appreciated
