Camera alignment
Following the scanner installation, you carry out an initial camera alignment
from the Scanner maintenance software. Thereafter, you only need to perform
this alignment depending on your needs after repeated scanning.
You must let the scanner reach the appropriate operating temperature before
making this adjustment (2 hours after you switch on the scanner). This
operation requires the
scanner maintenance sheet
provided in the Scanner
Maintenance Kit.
■
some models have a single fixed camera. Therefore, they do not require
camera alignment. The maintenance wizard will automatically detect the
scanner model and skip the camera alignment step.
■
Some models have two cameras, A, B starting from the right side of the
scanner. One is fixed and the other is adjustable.
The procedure below requires that you have installed the Scanner maintenance
software before.

To check the camera height (only for 2 and 4-cameras models)
1
Switch on the scanner and wait two hours for it to reach the optimal
temperature.
2
From the Windows ‘Start’ menu, select ‘Programs’ and start ‘Scanner
maintenance’. The maintenance wizard is launched.
3
Click ‘Next’.
4
Insert the
scanner maintenance sheet
face down into the scanner, lining up the
arrow at the center insertion point. The program immediately analyses the
alignment and stitching of the cameras. If cameras are unaligned, the program
will automatically make the necessary corrections.
5
Once the camera alignment is checked, the program moves automatically to
basic calibration.
Basic calibration ensures stable and clean scans by reducing noise and
unwanted effects caused by dust particles.
This operation still requires the use of the scanner maintenance sheet. The
program performs autaomatically the basic calibration and then moves to
Colour calibration to ensure long term stability of the linearity, colour balance,
and chromacity of your scans. You need to repeat this operation only about
once every two months of continuous scanning, or when the quality of scanned
colours becomes unsatisfactory.
