After producing several good prints, the miserable lines reappeared, ruining a print. Though one of the cartridges was low, I decided to redo the print head alignment. While waiting for one of the test sheets to print, the machine just stopped dead and shut down. It wouldn't restart. Nothing. I waited. I changed the (presumably) empty cartridge. Still nothing.
I looked into getting the newer comparable model, which would cost the same as this one did years ago. I'm not giving up on this one though, I have it on good advice that a new print head assembly would cure the problem, guaranteed.
Though it doesn't resemble a yellow citrus fruit, I think I have a lemon printer.
