5.1 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. The printer cleaning kit and 
cleaning sheets can be purchased from your authorised SATO representative.
When to clean with a cleaning kit
 For the print head, platen roller, paper sensor, and label guide: clean after using up every other roll of 
media.
 For other parts: clean after finishing every six rolls of media.
When to clean with the cleaning sheet
 For print head: clean after using every six rolls of media, or when you find any burned glaze on the surface 
of the print head.
