2.7 FOCUS ADJUSTMENT
Before installing the DS6100, the operator should select a specific reading area
by means of the optical system for manual adjustment of the focal length.
The focus adjustment is obtained by rotating a regulation screw which moves
the internal lenses and therefore causes the laser beam focusing position to
change.
Seven marks, numbered from 0 to 6, are printed on the regulation screw to
indicate the different positions of the internal optics. The diagram in par. 3.3
shows the reading performance that can be obtained from DS6100 scanners
when operating with different focus positions and barcode label densities.
Even though the screw is marked with seven positions, the focus adjustment
is continuous and not by step; this allows an optimum adjustment around the
selected position.
WARNING
The scanner must be disconnected from the
power supply during this operation to avoid
hazardous visible laser light.
Refer to the following instructions when adjusting the focus:
1) Unscrew the focus regulation cover (Figure A,
3
) near the laser output
window for access to the focus adjustment screw.
2) Carefully turn the screw counterclockwise until the number 0 is aligned
with the notch as shown in the following figure.
3) Now turn the focus adjustment screw clockwise to reach the desired
position (refer to the reading diagrams in par. 3.3).
