About two months ago, my 8400 flashed "replace right print head" and nothing could bring it back to life (eg, print head cleaning, resetting). As I use QImage to print an anti-clogging page every four days and had been doing so for more than two years, and printing large prints every couple weeks, I thought maybe the print head had gone bad or, more likely, that it was dirty and needed a good cleaning; many videos recommended Magic Bullet and because I needed to order it, I turned off the printer. When the Magic Bullet arrived finally, I kept meaning the print head, but I kept putting it off and was even thinking I'd get rid of the printer. Then I upgraded to Win 11.
This morning, I installed drivers for the 8400 and after a moment about a dozen unclog jobs came pouring out. No errors, I let 'em run. Any ideas what might be going on or suggestions as to what to do next. Of course, I could just cross my fingers and hope for the best.
