Zebra ZD421 & ZD411 Media Calibration

• Turn the printer on and load your media roll.
• Press and hold the Pause and Cancel buttons together for two seconds.
• The printer feeds a few labels to measure spacing and adjust sensing levels automatically.
• Press the Pause button once when finished to return to ready mode.

If your labels fail smart calibration, you may need to perform a manual liner calibration.

Manual Calibration

• Press and hold Pause for two seconds until all indicators flash yellow to enter advanced mode.
• Press Pause again when the status light turns solid yellow to select manual calibration.
• Open the printer and peel about 3 inches (80 mm) of labels off the liner.
• Position the blank liner directly over the movable sensor and close the printer.
• Press Pause once to measure the liner, then open the printer and move the media so a label sits over the sensor.
• Close the printer and press Pause once more to measure the labels, then press Pause to save and exit.
