Thank you everyone for the suggestion and information, removing the RIFA smoothing capacitor did the trick! I'm happily printing from the XLEnt Word processor
Side question - I didn't get a chance to use the printer before it gave up the magic smoke. Is it just me, or is it literally impossible to load a single sheet of paper without removing the ribbon? The paper feed seems to be designed in such a way that the paper doesn't curl around the platen tight enough to make it behind the ribbon guide. No matter where you place the head or angle the paper, it always knocks the ribbon off. Am I doing something wrong?
Thanks again for helping me get my 1025 back to life.
