To prevent damage during shipping, two shipping screws are attached to the transparency unit to secure its lamp assembly. You must remove these screws before using the transparency unit.

2.Use a Phillips head (cross
head) screwdriver to remove the shipping screws, as shown at right.
3.Install the screws in the storage holes.
Storage holes
If either screw is left in a shipping hole (the outer holes) while using the transparency unit, the unit may be damaged.
Before transporting the scanner, remove the transparency unit, reinstall the shipping screws, and turn the transportation lock on the side of the scanner to the 
locked position. See “Transporting the Scanner” on page 55 for instructions.
