## Long description

Replacement kit for Zebra ZD421T thermal label printers that includes the head open sensor used to detect when the printhead has been opened.

How to use
Power down the printer and disconnect it from its power source before beginning service. Remove the printer cover or access panel to reach the printhead assembly, following the manufacturer’s service manual. Remove the faulty sensor assembly and disconnect its wiring harness. Install the replacement sensor in the same mounting position and reconnect the wiring, ensuring secure seating of the connector. Reassemble the printer, restore power, and perform any required calibration or sensor checks via the printer utilities or service mode to verify correct operation.
Usage recommendations
Use only when the printer is powered off and unplugged; follow static-safe handling and Zebra’s service instructions. After installation, run a test print and observe that the printer pauses or shows the correct status when the printhead is opened. If the printer does not detect the head position correctly, re-check connector seating and mounting alignment or consult a qualified service technician.
