CLEANING AND MAINTENANCE

4.1 INTRODUCTION

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

• Cleaning the Print Head, Platen and Rollers

• Adjusting print quality
4.2 CLEANING 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. Depending on the
region in which the GL4xxe series printer was bought, a cleaning set and/or a set of cleaning
sheets may be provided with the unit. If any of the cleaning items need replacement, contact your
authorized SATO dealer.
When to clean with the 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.
4.2.1 DETERMINING WHEN THE PRINT HEAD NEEDS REPLACEMENT
♦ Check for vertical streaking in the same location of every label. If cleaning the print head does
not cause the streaking to be eradicated, then the printhead may be worn. Remove the
printhead and examine it for physical damage or wear.
♦ Load a different roll of labels and ribbon, and then run test prints again. If the vertical streaks
continue to surface, then the printhead needs to be replaced. See Page "2.4 Replacing the
Print Head" on page 2-18.
