 Chapter 11   Adjustments
The pressure of the thermal printhead against the ribbon or media is 
factory-adjusted. However, the use of thicker or thinner media than 
normal could require the printhead pressure to be readjusted.
Using a straight-slot screwdriver, turn the adjustment screw clockwise 
for more pressure (+) or counterclockwise for less pressure (-). Print 
a few labels and check the printout. Increased pressure generally 
gives a darker printout and vice versa. Repeat until the desired 
result is obtained.
To return to the factory setting, tighten the screw (+) as far as it goes 
and then loosen it (-) six full turns.
Caution!
Do not use a higher printhead pressure than necessary because it 
may increase the wear of the printhead and shorten its life.
