Step-By-Step Instructions To Replace The Printhead On The Zebra ZT231

Here’s how to replace the printhead on your Zebra ZT231 printer:

Step-by-Step Replacement Guide

1. Power Down & Prepare
• Turn the printer OFF, unplug the power and disconnect data cables.
• Open the media cover and remove any media and ribbon. Allow the printhead to cool to avoid burns.
2. Ground Yourself
• Attach an antistatic wrist strap or regularly touch the metal frame to prevent electrostatic discharge.
3. Release the Printhead
• Slide the printhead latch forward/unlock position.
• Tilt the printhead assembly upward—this pivots it free from the mechanism.
4. Remove the Old Printhead
• Carefully pull the printhead straight out of its clamp.
• Disconnect the ribbon cable connectors (the ZT231 typically has two).
5. Install the New Printhead
• Connect the cable connectors firmly to the new printhead (noting their keyed orientation).
• Slide the new printhead into the mechanism, aligning the locking posts with the latch holes.
• Return the latch to the locked position to secure it.
6. Clean the Printhead
• Clean the heating element strip using an alcohol swab from a Zebra Preventive Maintenance Kit or lint-free cloth with 99.7% isopropyl alcohol. Wipe end-to-end. Let it dry.
7. Reassemble & Test
• Reload ribbon and media.
• Close the printhead assembly and media cover.
• Reconnect power and cables, then power ON.
• Run a configuration/status report to verify the setup and functionality.
