Manually Calibrating Media

Use these steps to manually calibrate the printer for the loaded media.
This Advanced mode is typically used to calibrate the printer to media that is not correctly recognized during SmartCal media calibration.
You may have to perform manual calibration several times. This involves moving the media sensor each time until the printer completes the calibration process and returns to ready state.
  1. Place the printer in Advanced Mode (see Activating Advanced Mode) and press
    PAUSE
     () while the STATUS indicator () is lit yellow.
    The SUPPLIES indicator () flashes yellow, after which the PAUSE indicator () flashes.
  2. Open the printer and verify the media sensor is in the center position for label/gap (transmissive) sensing.

    For black-mark or notch media, set the media sensor to the proper location to sense the mark or notch.
    For pre-printed media with print located on the front of the label or on the back of the liner, position the sensor to a place where it will minimally sense/encounter the pre-print.
  3. Remove 80 mm (3 in.) of labels from the liner, then place the label-free area of the liner over the platen (drive) roller such that the leading edge of the first label is under the media guides.
  4. Close the printer and press
    PAUSE
     () one time.
    The Media indicator () flashes while the printer measures the media liner. When complete, the Pause indicator () begins to flash.
  5. Open the printer and reposition the media to locate a label directly above the movable sensor.
  6. Close the printer.
  7. Press
    PAUSE
     () one time.
The printer feeds and measures several labels. If it is able to determine the correct media type (gap, black mark, or notch) and measure the media length, it returns to Ready state.
