4.1 CLEANING THE PRINT HEAD AND PLATEN ROLLER
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 media 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
