plate in position. Verify that the bar is locked in place before

10. Open the User Utility and perform a shading adjustment before
scanning.
The scanner’s default background color is black, therefore it has
never been calibrated to use the white background. When you
change the background color to white the first time, you should
perform a shading adjustment. Please see “Shading Adjustment” on
page 111 for instructions.
