First, a disclaimer: I hate printers. I mean, I really do. It’s a voodoo industry, full of cheap-yet-secretly-expensive devices, that seem intent only on never working exactly as they should. They are consistent in their inconsistency, and reliably rubbish. Inkjet printers have ink that costs enough to make you think they need harvest unicorn blood, and laser printers are the size of a unicorn stall. Or weird little gears and gizmos go out of whack, like some sort of fiendish goblin contraption, and it literally costs more than a computer to get the part replaced.
All that being said, there are a few, tried and true, reliable things that fix 95% of the problems people call me about when it comes to printers. Theres lots of OTHER things that go wrong, but this little procedure is what I always try first, and it generally does the trick.
