4.1 WHEN TO CLEAN 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 from dirt and adhesive that constantly accumulate on the print surface.
Furthermore, dirt can accumulate along the media path, affecting parts like sensors and guides, and reducing
their performance.
You can get the cleaning kit and the cleaning sheet from your SATO reseller or technical support center.
The cleaning kit
• Clean the printer head, platen roller, media sensor and media guide when you have used one roll of media.
• Clean other parts when you have used six rolls of media.
The cleaning sheet
• Always clean the print head when there is any burned glaze on the surface of the print head. Clean the
print head when you have used six rolls of media.
