Printronix: GAP NOT DETECTED

A “GAP NOT DETECTED” error means that the printer was not able to find the gap/mark between labels. There are a few potential causes for this error:

  1. The printer has not performed a media calibration on the labels
    • Solution: Calibrate your printer.
  2. The labels are not feeding out of the printer correctly (most often because the labels were back-fed too far into the printer)
    • Solution: Ensure that at least 1 label is sitting past the roller.
  3. The media sensor is in the wrong place (it should be underneath the labels, lined up with the gap)
    • Solution: Ensure that the media sensor is sitting directly under the labels, so the gap between the labels will pass over the sensor when feeding/calibrating.
    • After adjusting the sensor, please calibrate your printer again.
  4. The printer is set to the wrong media type (Gap vs. Mark)
    • Solution: Ensure that the Sensors > Control > Gap/Mark Sensor is set to the value that matches your labels.
