My family used to use an Epson CX4600 (I think thats the model, can't remember off hand) All-in-One on the PC we have, but recently it just stopped printing. My Dad bought new cartridges, but they didn't change a thing. So he went out and bought a new HP, and gave me the Epson. I figure the ink nozzles probably just need cleaning, so is there an easy way to go about this?
