@batteryheadbill - thanks so much... I did the printhead cleaning multiple times, finally I replaced the printhead and still got B200! I gave up and was researching for new, comparable machine and decided to search for help one last time when I stumbled across your posts and threads so figured 1 last try and after following your instructions it works!!! Had to repeat a few times but it's back on track! Love my MX870 and you're awesome! Thank you again!!!
