When your ZT111 printer encounters a head open error, you'll typically see a steady red light (status) and a solid yellow light (pause) illuminated.
If so, follow the steps below to resolve the error.
Open the media door.
Examine the printhead assembly to ensure the printhead is closed. In the images below, you will see the correct and incorrect ways to secure it.
If the error doesn't clear, examine the printhead closed sensor to ensure it's free from debris, dust, or contamination. You can use a dry lint-free cloth to clean the sensor eye.
If the error is still appearing after completing all steps, please open the printhead and turn off the device. Close the printhead completely and turn on the printer. Please contact the support team for further assistance.
