I built a pc for someone just before Christmas of 2002. Today she asks me to get the printer working as apparently it never had. I hooked it up but it only prints the MS Windows flag on the "Print Test Page" of it's properties menu. I did many "deep cleanings" without returning to normal. I suppose I need fresh ink, but all the colors seem to show up on different attempts, but never all together. Could the jets be clogged? How do I clean this up?
