Printhead Pressure
The pressure of the thermal printhead against the ribbon or
direct thermal media is factory adjusted. However, the use of
thicker or thinner media than normal could require the printhead
pressure to be readjusted.
Turn the adjustment knob clockwise for increased pressure, or
counterclockwise for less pressure. Print a few labels, preferably
test labels, and check the printout. For help printing test labels,
see “Setting Up the Printer” on page 59. Increased pressure
generally gives a darker printout and vice versa. Repeat until the
desired result is obtained.
To find the basic setting, turn the knob counterclockwise until
there is no pressure left. Test with a piece of media under the
printhead. You should be able to pull it out without more than
just a little resistance. Then turn the knob four full turns
clockwise. Fine-adjust using the trial-and-error method.
Printhead pressure adjustment
Do not use a higher printhead pressure than necessary.
Unnecessary pressure may increase the wear of the printhead
and shorten its life.
