Adjusting the Print Quality
One of the nice features of the
PANDUIT
®printers are their high print quality.They are equipped with two
different methods of adjusting the quality of the print;pr int darkness and speed.When adjusting for optimum
print quality, a bar code verifier system should be used.The human eye is a poor judge of the relative widths of
the bars in a symbol, a characteristic that is extremely important for good bar code quality.

PRINT (DARKNESS)

This adjustment allows the user to control (within a specified range) the amount of power that is used to activate
the individual print head heat elements.It is impor tant to find a proper print darkness level based on your
particular label and ribbon combination.The pr inted images should not be too light nor should the ink from the
ribbon “bleed.”The edges of each image should be crisp and well defined.
The Print Darkness can be set using the front panel LCD panel or by downloading the setting using the Print
Darkness software command.Once the range has been selected, the PRINT Potentiometer on the front panel
can be used to make finer adjustments.
The primary adjustment for Print Darkness is the PRINT potentiometer on the front panel. It provides a
continuous range of adjustment, allowing you to make precise changes.Use a small cross-point screwdriver,
turning clockwise for darker print and counterclockwise for lighter print.

NOTE: The PRINT potentiometer adjustment will affect the darkness in all of the command code speed ranges,

i.e.if the PRINT potentiometer is adjusted for lighter print, the darkness will be lighter in all speed ranges

selected by the command code.
