Introduction

The Platen Assembly and the Media Rollers of the Printer are parts subject to wear and damage in the same way as are automobile tires. The Platen Assembly and/or the Me- dia Rollers should be replaced if they show damage such as cuts or nicks on their sur- faces or excessive wear. Badly worn Platen Assemblies and Media Rollers can cause poor quality printing, improper tracking of the media and contribute to label jamming when trying to dispense labels.

There are two replacement kits for the Platen:

•AN16753-021: For Printers using media with a removable liner

•AN16753-022: For printers using linerless media.

This guide will detail how to install a replacement Platen Assembly.

Refer to the User’s Manual for guidelines on cleaning the printer to increase the working life of the Platen Assembly and the overall efficiency of the printer.
