4. CCD-Cameras
The adjustment procedures presented in this chapter cover all adjustments needed for
replacing the complete CCD-camera.
It will hardly ever be necessary to replace mechanical parts such as Lens, Camera Housing,
etc., and in most cases, the only adjustments necessary after replacement of the CBE/CBF-
Board are:
•
Check Scan-Width. If it is within the limits given in Section 4.2.5, page
99, then Focus will also be OK.
•
CCD-Centering, Section 4.2.6 page 109
•
Vertical Positioning, Section 4.2.7, page 110
•
Run Scanner Maintenance, Section 6.1.7, page 142 to do
Vertical Alignment and Stitching
Basic and Color Calibration
These adjustments can be made without loosening the Camera Fixing Screws and
without loosening the Focus Lock Ring / Lock Screw.
4.1 Description of CCD-Cameras
See:
Fig. 4-1 Focus Lock Mechanism, page 82
Fig. 4-2 CCD-Camera, Side View, page 83
Fig. 4-3 CCD-Camera, Top View, page 84
The CCD-Camera basically consist of:
•
Lens
•
Lens Adapter
•
Camera Housing
•
Camera Back-Plate
•
CCD Mounting Plate
•
CBE/CBF-Camera Board
•
Camera Base Plate
•
Camera Motor, on Adjustable Cameras only
The parts of the CCD-Camera are mounted on a Camera Base Plate, and the complete CCD-
Camera is mounted on a Mounting Platform, which is welded to the scanner chassis. The
Camera is positioned with the optical axis perpendicular to the scan-area by means of two
guide pins extending from the bottom of the Base Plate down into two slots in the Mounting
Platform.
When the three Camera Fixing Screws are loosened for Camera Adjustment, two tension
springs pull the Camera Base Plate down against the Mounting Platform. Another spring pulls
the CCD-Camera in forward direction to keep the Scan Width Adjustment Screw in contact
with the scanner chassis, and to the left to align the guide pins with the left edge of the slots in
the Mounting Platform.
