Stuck on "warming up"
Sorry, forgot to get back to ya..
anyway, remove control panel cover, remove button panel, you will see a little tab right at the top, push that down and unlock and discconect, remove small ribbon on the underside. use torx driver and remove screws so that you can remove the whole top gray housing, you want to access where the scanner bulb comes to rest, there will be a black plastic cover over the scanner bulb, REMOVE THAT PIECE, its about 2" wide by 10" long, unclip it by putting small screwdriver in small rectangular slots and pry lightly to the right, there are little tab locks in there.
With that removed, just put things back loosely to see if the warming up stops when turning on or trying to use scanner, if everything works well, do alittle cleaning and put thing all back together.. this should solve your warming up promlem..
