Maintenance & Troubleshooting Manual

1

Introduction

This Maintenance Guide contains information to assist skilled and trained technicians in the maintenance,
troubleshooting, and repair of the TRAK 3ntr 3D printers. It is far from complete; however, directly
addresses the most commonly encountered issues that require maintenance, service, and/or
troubleshooting with the TRAK 3NTR A2/A4 3D Printers.

Scope of the Maintenance Manual:

•

Diagnostic Checklists/Flowcharts

•

Repair Procedures

•

Maintenance Procedures

•

Upgrade Procedures

Although there is a Main Diagnostic Checklist available as a starting point for printer troubleshooting, this
guide is most efficiently utilized browsing the table of contents to select the applicable Repair Procedures
section content.

CAUTION

- Information contained within this manual is a reminder for trained personnel only. This

manual does NOT replace training

–

untrained personnel should not perform any maintenance on any

3ntr machinery even if dutifully following the procedures depicted into this document.
