L7680 Error Message- Missing or Damaged Cartridges

[Marko]

Hi, this is my first post hope you can HELP I have a HP Officejet Pro L7680 All-In-One running Windows XP. My warranty expired in 2008. I getting a error message and a yellow light flashing on my printer that reads the following ink cartridges appear to be missing or damaged. There is also a symbol K. One last thing says Refer to Printer Documentation. It seems that it is frozen, I tried to move the arrow buttons but it does move. I turned the printer on and off, removed the power cord, USB ECT. The one problem that may or may not caused this could be is that I did not use hp cartridges, I used refurbished ink cartridges. Is there anything I can do fix this problem. I know how costly it can be to bring it in to be serviced. Or am I screwed for being cheap and trying to save money purchasing those ink cartridges. Hope you can HELP!! P.S. Do Not have the manual any more.
