How to Change Printer Thermal Ribbon for SATO CLNX Printer

This article demonstrates how to change the ribbon in your Sato RFID printer

SATO CLNX RFID printers use a thermal transfer ribbon to print text, barcodes, and RFID data onto labels and tags. Over time, the ribbon will be consumed and must be replaced to ensure consistent print quality and reliable RFID encoding.

This guide walks through the process of removing a used ribbon and installing a new one on a SATO CLNX printer. Following these steps will help prevent print errors, ribbon wrinkles, and damage to the print head, ensuring the printer continues to operate correctly.

Prerequisites

  • SATO CLNX RFID Printer

  • Replacement roll of thermal ribbon

Additional ribbon can be purchased from local suppliers such as Peacock Bros. For information on which size ribbon is suitable for your printer, email: support@ramp.com.au
