Set the print head to substrate gap
between 0.2 and 2.0mm.
The air pressure should then be
increased until a good quality print is
apparent. As a rough guide, during
printing this should be 2.5-3.5 bar on
the printer’s rear air pressure gauge.
Print contrast levels should be set in
relation to the print speed.
For example, if the print speed is high,
the print contrast may have to be raised
to achieve good print quality.
If the print speed is lowered, the print
contrast should be reduced
accordingly. As a general rule contrast
levels should be kept as low as the line
speed and print quality requirements
will allow. This will ensure that the print
head life will be used to its optimum.
Contrast levels that are too high may
also contribute to poor print quality or
ribbon breakage (especially when
printing barcodes or horizontal lines).
The maximum contrast level for any
print speed is 120%.
Faded print
Print quality is dependent on the
following:
Quality of the substrate and ribbon
being used, print contrast, print speed
combination and the condition of the
machine being used to print.
The age and storage conditions of the
ribbon can also affect the print quality.
Keep the print head clean by using
Cleaning Pens (P/N VPR0223),
Cleaning Fluid (P/N WJ-111) and Print
Head Cleaning Wipes (P/N MT25215).
Never touch the print head with an
abrasive material or metallic object.
Recommendations:
Clean the print head and platen
Increase the pressure
Increase the contrast
Reduce the print speed
Review ribbon.
