Hello... Just wanted to post on here a solution to an issue that many people are having with their HP all-in-one multifunction printer/scanner/copiers.

I have an HP Photosmart C5180, and after about 4 years of light use, it started displaying "ink system failure". It was able to be cleared up with a hard reset, but would always come back after one print job. Then finally it stopped turning on at all... would just power cycle non stop displaying the HP logo and loading bar on the screen the whole time. Sometimes the exclamation point would light up when it was cycling....
