since upgrading to the bundle and the firmware as well. nothing about this printer works in any way. will not print, the material handler does not work in any way.. i have unhooked the material handler and the top air portion. the machine still doesn't work. i have tried rolling it back with the bundle parts un attached. nothing. it still see the bundle parts . does not work. in the process of boxing the bundle parts back up. untill this is fixed do not buy the material station. just junk.
