Calibrate the Printer
Auto Calibration
By default, the printer automatically calibrates on power up or when the printhead is closed.
During auto calibration, the printer determines the label length and sensor settings.
The results of the auto calibration are stored in the printer’s memory and are retained even if
printer power is removed. These parameters remain in effect until the next calibration is
performed.
Manual Calibration
Perform a media and ribbon sensor calibration to reset the sensitivity of the sensors so the
media and ribbon are detected more accurately. If you change the type of ribbon or media,
your printer may operate better if you perform this calibration.
For instructions, refer to Calibrate Media and Ribbon Sensor Sensitivity on page 74 .
Note • If the control panel settings for MEDIA POWER UP or HEAD CLOSE are set to
LENGTH, NO MOTION, or FEED, the printer starts printing without auto calibrating. See
Select Media Power-Up Option on page 80 or Select Head Close Option on page 80 .
