can be detected by the ribbon sensor. Under the
printhead, the ribbon should track all the way back,
near the printer’s firewall. See Load the Ribbon on
page 48.
2. Calibrate the printer. See Calibrate the Ribbon and
Media Sensors on page 89.
In thermal transfer mode,
the printer did not detect

the label and ribbon being used.
Calibrate the printer. See Calibrate the Ribbon and
