Step 4Calibration and Tilt
Look at the preview scan below.
The paper tubes on or near the center line show the best place to scan lumpy (3D) small objects.
The tubes further away all seem to lean in towards the center line. This is because the scanner sensor is mounted on the center line and uses mirrors and a lens to capture the entire width of the glass.
Note that there is no tilt up or down. Only sideways. Sort of like walking down the middle of a road and seeing the trees and buildings leaning in over you.
It also helps to place an accurate drafting ruler in different positions to check for accuracy.
