Just adding one more voice to the chorus on this - I’ve had the same problem. It started after I switched to the LT tank and Rigid resin, so I assumed the new cartridges had a chip issue. Looking at the thread, looks like that may have been too simplistic of an assumption. In any case, I haven’t been doing any trouble shooting because it seems like an obvious software/firmware issue and I’m just waiting it out. Will look into using Open Mode - thanks for the tip on that, all.
