FAQ for Zebra GX420t Thermal Printer Ribbons

What ribbon sizes are compatible with Zebra GX420t?

The Zebra GX420t accepts ribbon widths from 1.33" ~ 4.30" (33.8mm ~ 109mm). Standard lengths include 74 meters. Choose a ribbon at least 0.5" wider than your labels for optimal coverage.

What types of ribbons work with Zebra GX420t?

The Zebra GX420t supports three ribbon types:

  • Wax: Most economical. Best for paper labels and indoor use.
  • Wax-Resin: Better durability and scratch resistance. Good for synthetic labels.
  • Resin: Maximum durability for harsh environments and polyester labels.

Choose based on your label material and durability needs.

How do I calibrate the Zebra GX420t?

If your Zebra GX420t is skipping labels or printing incorrectly, calibration is needed:

  1. Turn off the printer
  2. Press and hold FEED button while turning on
  3. Wait for the status light to flash
  4. Release - the printer will feed labels to calibrate

This teaches the printer to detect label size and gaps. Calibrate when changing label sizes.
