My printer was working fine yesterday. The BB core got jammed, so I took it out, cleaned it up, and was going to put it back in, when I noticed that the spring that pushes the printcore down had sprung out of place. So, I took the entire print head off of the rails and disassembled it so I could get the spring back into place. I also took out the AA core at this time to clean it up. I put it all back together again, and there seemed to be no problems until I tried to load the printcores back into place. Right now, for both printcores, the screen on the printer says "empty slot", which it should, since there aren't any print cores in there.
The problem arises when I tell it to "Load" either printcore. When I press this button, the machine will home itself out, then ask me to lower the fan bracket (the blue light turns on as well). I press confirm, and the screen prompts me to press the core in place. When I do this, the printer must recognize it, because the light turns orange and it asks me to close the bracket again. The printer then homes itself out again and all seems fine until it still says "empty slot" when I look at the printcore/material selections on the screen.
The exact same thing happens to both printcores. I have cleaned the connections in back of the print cores with isopropyl alcohol, tried restarting the machine, and repeating the printcore installation process a few times.
