If you can’t insert the shipping screw in the hole labeled CLAMP when you prepare the scanner for transportation, the TPU’s lamp assembly may not be in its home position. If this is the case, slowly raise the front of the TPU to allow the lamp assembly to slide to the home position.
Before transporting the scanner, turn it off, remove the TPU, and reinstall the shipping screw in the outer shipping hole labeled CLAMP. The transportation lock at the back of the scanner must also be in the LOCK position before you move the scanner (see Setting Up and Using Your Scanner).
Installing the Transparency Unit
Follow the steps below to install the TPU:
1Make sure the scanner is turned off. Then unplug the power cable from the scanner.
2Remove the document cover by grasping the back of the document cover as shown and easing the cover up.
