PROCEDURES
ADJUSTING THE PRINT QUALITY
The CT400 and CT410 printers are equipped with two different methods of adjusting
the quality of the print; print darkness and speed. When adjusting the printer 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.
Darkness (Print)
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 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.
The print darkness level can be set by downloading the setting using the <ESC>#E
Print Darkness software command (see Section 4, Programming Reference). There
are five ranges 1 through 5, with the lightest setting being 1 and the darkest setting
being 5. The <ESC>#E Print Darkness command also provides for darkness ranges
matched to the type of media used. Setting “A” is used Direct thermal media and “B”
for coated thermal transfer media.
Once the range has been selected, the PRINT Potentiometer on the front panel can
be used to make finer adjustments.
