Had a lot of bother with printers.  The first one I got would print a page, and then reel out several pages containing only one line of symbols.  Until I punched it in frustration and it very, very gingerly pulled through a single untouched blank page.  This wasn’t a permanent fix, however, but it felt good at the time.  Please note: I don’t condone the use of violence against printers, but it’s a good, if messy way to take them apart for recycling.
