Hello guys,
I had issues with the old printer heads and decided to replace them. I bought new HP brand printer heads and installed them. after printing a test page and afew other documents. The printer started giving me " Printhead has a problem: and it says that both printhead have the "problem". I tried cleaning the contacts and the printheads and the printer and shuting the printer down. Nothing seems to work. Any advice? this is an Officejet pro L7580. Any help is appreciated. thanks
