Running a SmartCal Media Calibration

The printer must set media parameters for optimal operation prior to printing. To do this, it automatically determines the media type (web/gap, black mark/notch, or continuous) and the measure media characteristics for printing.
  1. Make sure media is loaded (and also ribbon if you are using thermal transfer mode) properly in the printer and the top cover of the printer is closed.
  2. Press
    POWER
     to turn printer power on and wait until the printer is in the Ready state.
    The STATUS Indicator lights solid green.
  3. Press and hold
    PAUSE
     and
    CANCEL
     simultaneously for two seconds, then release.
    The printer feeds and measures a few labels and adjusts media sensing levels. When it completes measuring, the STATUS indicator lights solid green.
After initial calibration to a specific media, additional calibrations are not necessary for newly-loaded media as long as it is of the same type as the prior media used (media type, vendor, batch, size, etc.). The printer automatically measures the newly-loaded media and adjusts for any small changes in its characteristics when printing.
After you load a roll of new media from the same batch, you can synchronize the labels and get the media set for printing by simply pressing
FEED
 (Advance) once or twice.
If the printer should fail to recognize and correctly calibrate to the media, see Manually Calibrating Media.
