Chapter 7 Print Unit
Adjustment
When you print, the thermal printhead must be pressed against the
print roller so that heat can be transferred from the printhead to the
transfer ribbon or direct thermal paper. The pressure should also be
great enough to provide sufficient friction to drive the paper past the
printhead. Too little pressure gives a weak printout quality, while
too much pressure can cause ribbon wrinkling and unnecessary
printhead wear.
The printer's factory setup is for full width, thermal transfer printing
(2.0 – 2.5 kp on each knob). When you change the media (to thicker,
thinner, or narrower), it may be necessary to adjust the printhead
pressure, using trial and error.
Do not use any more pressure than is necessary to obtain the desired
print quality.
