4.5 ADJUSTING PRINT QUALITY

Print quality can be optimized with regular cleaning and maintenance of the print head and components along
the label path. Additionally, you can fine-tune print quality by adjusting print darkness and print speed settings.

4.5.1 Adjusting Print Darkness

This adjustment allows the user to control (within a specified range) the amount of power applied to the
individual print head heat elements. It is important to find a proper print darkness level based on your
particular label and ribbon combination. The printed 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.
PRINT DARKNESS — The Print Darkness can be set from the Normal
Mode menu. There are five settings, from 1 (lightest) to 5 (darkest). The
default setting is 3.
Once the range has been selected, the setting of the Print potentiometer
can be used to make finer adjustments.
Print potentiometer — The fine adjustment for Print Darkness can be
done by adjusting the Print potentiometer on the front operator panel. It
provides a continuous range of adjustment, allowing you to make precise
changes. Maximum print darkness is obtained by turning the
potentiometer all the way clockwise and maximum counterclockwise
setting will give the lightest print.
Note:
The Print potentiometer adjustment will affect the darkness regardless of the speed and darkness ranges
setting.

4.5.2 Adjusting Print Speed

Besides varying the rate at which labels are printed, this adjustment can
be used to regulate any changes in print quality.
PRINT SPEED — Print Speed can be set from the Normal Mode menu.
Setting range differs by print resolution and print mode.
