Preface
The G Series Industrial printer is designed to provide industrial strength thermal printing in a small footprint. POSTEK
G2000/G3000/G6000 barcode label printers represent a new generation of printing equipment featuring high performance
capability with multiple functions. This printer stands out with its new and cutting edge technologies. Carefully designed, the
G Series Industrial model is rugged, durable and easily operated and maintained. The 32-bit embedded ARM CPU and
high-tech system platform delivers the highest quality possible.
This manual explains how to set up and begin using your G Series Industrial printer. It also provides detailed information on
configuring your printer, basic operations, care and troubleshooting.
Please read this manual carefully before using the G Series Industrial printer.
Important Notice, Read Me First
The thermal printhead can be easily damaged due to its precision construction. A printhead damaged by misuse is not
covered under the terms of the warranty. To ensure longevity of the printhead, please note the following:
1. DO NOT scrape or use tools that might damage the printhead surface.
2. To protect from corroding the printhead, DO NOT touch the printhead with bare hands.
3. DO NOT use thermal paper or thermal transfer ribbons which contain Na, K or Cl.
4. Keep printhead from any form of liquid or dampness.
5. Only use a cotton swab dipped in anhydrous isopropyl alcohol to clean the printhead.
6. Always use high-quality consumables:
•When the printhead module is closed, pressure is placed directly onto the printhead; dirt such as paper scraps, sand,
dust and glue can scrape or damage the printhead.
•The TPH is also easily damaged by static electricity, which may be generated by poor quality ribbons.
7. Always inspect consumables for high quality before purchasing.
Note: The G Series printer functions under Direct Thermal or Thermal Transfer print methods. Thermal Transfer is set as
the factory default (requires ribbon for printing). However, if you need to print on Direct Thermal materials (ribbon is not
required), please contact your printer supplier or service provider to reduce the printhead pressure. This can protect your
printhead from early performance deterioration due to direct contact with the thermal media. Any physical printhead
damage caused by direct thermal printing is not covered under warranty.
