Focus Adjustment:
The DS6300 provides a manual adjustment of the optics to optimize the reading performance by choosing the
best focus between two extreme positions. The focus adjustment is continuous and not by step; thus, allowing an
optimum adjustment around the selected position. The relative focus positions range from 0 to 100.
The adjustment can be simply made through an external screw placed on the back of the optic HEAD and
protected by a cap. The screw may be rotated either clockwise or counterclockwise in order to move the scanner
internal lenses. In particular, a clockwise rotation causes a farther focus from the scanner, while a
counterclockwise rotation causes a nearer focus to the scanner.
An internal sensor tracks the exact laser beam focusing position allowing it to be shown on the reader display or
through the Genius™ software program.
WARNING
Do not stare at the laser beam output window during this operation to avoid hazardous visible
laser light.
Refer to the following instructions when adjusting the focus:
1) Remove the regulation screw protecting cap (see following Figure) positioned on the back of the optic Head;

Display Visualization
The first line of the display shows the read code and Good Read percentage. Possible suspending commas
at the end of the code mean that the code is too long to be displayed.
The second line of the display indicates the value of the focus position according to the table below. The
indications “Too Near” or “Too Far” are represented for values outside the focus range.
