The laser/scanner is not a FRU. If the laser/scanner mirrors are contaminated, the entire product must be replaced.
      caution:
    The ADF and scanner cover are not captive and can open suddenly when the product is placed front-side face up. Always support the ADF and scanner cover before placing the product front-side face up.
    Do not lift the product grasping the front door and Tray 2 cavity.

      caution:
    Do not touch the spongy roller surface unless you are going to replace the roller. Skin oils on the roller can cause paper pickup problems.
