Hey all, I ran out of black ink on my hp deskjet 5150 and quickly refilled it with decent quality ink. However when I went to print again, it went halfway through a page before declaring the printer to be out of ink (the half page that printed came out beautifully). Of course, the ink cartridge is just telling the computer it's printed as many pages as it was designed to do. Does anyone know of a way to either reset the ink level, or fool the computer into thinking the print cartridge is just fine? I already tried ditching the prefences thinking that serial # of the cartridge must be recorded somewhere. No luck any help?
