Use the arrow keys to change the print contrast. The higher the
number, the darker the print; the lower the number, the lighter the
print.
The print contrast controls the darkness of the printing on your
supply. The range is –100 to +100 and the default is 0. You may
need to increase or decrease the print contrast depending on your
supply type.
The correct print contrast setting affects how well your bar codes
scan and how long your printhead lasts.
The gray scale test checks the uniformity
of the printing. The printed sample
should be uniformly gray across the
supply. If you see voids, especially on
the edges, keep the sample and call
Service.
