Zebra Technologies T300 Printer User Manual


 
Turn the printer on by pressing the Power Switch on the rear of the printer.
The Power light will turn on. The printer performs a set of internal diagnos-
tics, and after the diagnostics have been completed (within 1 - 10 seconds)
the motor may start briefly.
If loading the printer with media for the first time or if you are changing the
type of media you’re using, perform a calibration. See “Calibration” on
page 18.
The thumbwheel on the side of the printhead allows the printhead pressure to
be adjusted for media narrower than the width of the printhead. To adjust,
rotate the thumbwheel to the left until the print quality along the edge starts
to lighten. Then rotate the thumbwheel to the right just enough to achieve
uniform print quality across the label. See Figure 4.
Refer to picture 10 on page 7. If you are using narrow media, hold the ribbon
spindle while turning the ribbon tension adjustment knob clockwise. For
full-width media, set the knob to the counter-clockwise direction. If your
media is somewhere inbetween, experiment until you get good results.
