5.1.8.1Line Splice Adjustment
Line splicing is matching or aligning the cameras so they all will encounter a line parallel to the row of the cameras at the same times. If the cameras do not encounter the data at the same times, the line will appear broken.
If one camera encounters data before adjacent cameras do, that means it is tilted too far towards the front of the scanner. If it encounters data after its neighboring cameras, it is tilted too far back.
In case of very slight misalignment, adjustment can be made electronically. For greater misalignment, adjustment can be made mechanically by actually tilting the camera either forward or backward. This is done by turning an adjustment screw on the camera block.
This adjustment can be made with any high contrast document containing parallel unbroken lines. Any break appearing on the monitor will signal a line splice problem.
5.1.8.1.1 Adjusting Line Splice Mechanically
Procedure for Mechanical Line Splice Adjustment:
1.Using “Splice and Merge Adjustment” in the diagnostics software, scan a test document, view each camera boundary, and then diagram the overall splice condition of the system on a piece of paper. Each line represent a camera and the picture shows the splice relationship among the cameras
2.Pick a reference camera by which you will adjust all the other cameras. Any camera can be the reference camera; however, for ease of adjustment, use a camera which is located roughly half way between the two extremes.
3.The splice is adjusted by turning an adjustment screw on the camera blocks. Turn the screw clockwise to tilt it back, delaying the data, or turn it counterclockwise to tilt it forward, to get the data earlier.
Adjust the camera closest to the reference camera first and then go on to the next closest camera in that direction.
