Since my other printer stopped working, I decided to try to get an new printer. I went shopping around, then saw a very good deal on an old HP DeskJet 820Cse at a local used computer store. It's a good (but slow) color inkjet from the late 1990s. It only cost me $30, too. But anyways, it's been working fine for about a week, when all it jams. I open up the printer, fix the jam, and it works again. I turn the printer on the next day. It sounds normal turning on, then it makes a whirring sound and an extremely loud CLUNK. Does anyone know what this could be?
