I have Colorqube 8580, which has some issues. It will continuously boot and errors are 94.526 (Y-axis fault) and 91.721 (Printhead tilt fault). It will warm up until ~28% and boot. Usually, it makes kind of jerking sound (maybe from the drum) before error.
It seems to have some paper jam problem as well. When I try to test paper path in service mode, it will always jam. Paper is rather oily when I pull it out.
