Camera not shoot at center

[kentsin]

After building the scanner, I find out the camera is not taking the photo at the center position. When capture a A4 paper with a 55mm len the left camera and the right camera have a different of 9.5 cm. Which need to adjust one camera to about 5.5 cm.

I would like to ask if anyone have experience the same problem before? How I can avoid to change my design to add another dimension of movement?
