hello those sensors are down? because the only thing I take out is the fuser, I changed the filimina, before the printer printed but I cushioned the sheet by the broken filimina, then I bought the filimina that came to me without the special grease and placed it, in the fuser everything enters one way, impossible to confuse me in assembling the fuser
not to assemble the fuser but when I take it out I think I don't remember that model precisely you also have to disconnect or remove the cables that go to the tonner sensors and papers are mobile plastic pieces that interrupt the passage of the lus between two black turrets
