Recalibrating a label printer will resolve the following types of issues: 

  • The label printer prints, then skips a label (or is skipping labels).
  • The label text is overlapping onto the next label. 
  • The print position is drifting up or down the label. 
  • The labels stop printing in random locations. 
  • The label prints but then the Feed button on the printer starts to flash red. 


This article covers troubleshooting steps for the following models of printers - refer to the appropriate section, below, for details: 

  • Zebra LP2824
  • ZebraLP2824+

  1. Make sure the printer is turned off and that the media is loaded.
  2. Press and hold the Feed button, then turn on the power. 
  3. When the status light blinks, release the Feed button.
  4. The printer will advance the media to measure and verify the length of the individual labels or tags. The printer will then print a status summary and remain in diagnostic dump mode.
  5. To begin normal operation, tap the Feed button. The printer will print “out of DUMP” text and then advance a label.
