    note:
    If you are also installing optional 550-sheet trays, place the optional trays on top of the 2x550-sheet paper tray accessory first, and then place the printer on top of the optional 550-sheet tray(s).
      caution:
    Due to the weight of the printer, HP recommends that four people move the printer to place it on top of the 2x550-sheet paper tray (or the optional 550-sheet tray).
    All trays must be closed when moving the printer.
     
      warning:
    Back surface may not align on all models. The M856 and E85055 are larger than the accessory. Align the front surface and not the rear of the printer.
