Printhead Pressure Adjustment
1.
Selecting 2 ips from the
printer or the label
software, print several
test labels.
2.
During the test printing,
use the LCD panel to
lower the darkness
setting until the labels
print gray instead of

1.
On the toggle assemblies, loosen the Upper knurled nuts found above the adjusting nuts.
2.
Looking down at the printer, use the adjusting nuts to increase (clockwise) or decrease
(counter-clockwise) pressure until the darkness is uniform across label.
3.
Once uniformity is achieved, adjust the darkness level on the LCD until printing is clear.
4.
Tighten the Upper knurled nuts against the Adjusting nuts.
Too much pressure
applied to the toggles
will shorten the life of the
Printhead. Choose the
lowest pressure that
produces the desired
print quality, which will
maximize Printhead life.
