CLEANING AND MAINTENANCE

4.1 INTRODUCTION

This section provides information on user maintenance for the GT Series printers. The following information is covered here:

•Cleaning the Print Head, Platen and Rollers

•Adjusting print quality

4.2CLEANING THE PRINT HEAD, PLATEN AND ROLLERS

The print head not only generates printouts of barcodes, but also graphics and text. To produce optimal printing, it must be kept clean in spite of the dirt and adhesive that constantly accumulates on its print surface. Furthermore, dirt can accumulated along the label path, affecting parts like sensors and guides, and reducing their performance.

Therefore, it is important to clean these important components periodically. A printer cleaning set and a set of cleaning sheets is provided with every printer. If any of the cleaning items need replacement, contact your authorized SATO dealer.

When to clean with the supplied cleaning set

♦Printer head, platen roller, paper sensor, and label guide: clean after using up every other roll of paper, or each time after printing 150 m.

♦Other parts: clean after finishing every six rolls of paper, or every time after printing 900 m.

When to clean with the supplied cleaning sheet

♦Printer head, platen roller: clean after using every six rolls of paper, or every time after printing 900 m.
