The scanlines from the individual cameras are mechanically aligned (by means of a small
electric motor) in the vertical direction. The Vertical Alignment and the Horizontal Stitching
may be done automatically by means of either SCANtest 6, Test 11 or as part the Scanner
Maintenance calibration procedure.

The Automatic Thickness Adjustment Control (ATAC) automatically adjusts for media
thickness up to 0.6 inch (15 mm). The motor driver board (MDA) and the motor for the
ATAC system are located in a non-removeable Original Guide Plate.
The scan-area is illuminated by one white fluorescent lamp. The light output from the lamp is
stabilized by feedback to the lamp power supply board (LME).
Each CCD-Camera in the scanner contains one 7500 x (3+1) pixel (RGB Triplets +
Panchromatic B/W) CCD. The output signals from the CCDs are Light Profile Corrected at
pixel level.
All scanning and image processing functions are contained on only two boards, the Camera
Board (CBF) and the Controller Board (SUC).
The computer Interface Module (IMD) contains:
