following information is covered here:
• Cleaning the Print Head, Platen and Rollers
• Adjusting print quality
• Replacing the protective fuse
• Replacing the protective Print Head
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. This is done with a
printer cleaning kit or cleaning sheets (for print head cleaning only), available separately from
your authorized SATO dealer. When the cleaning materials run out, be sure to obtain only
certified replacements from your dealer.
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 paper, or each time after printing 150m.
♦ For other parts: clean after finishing every six rolls of paper, or every time after printing 900m.
When to clean with the cleaning sheet
♦ For the print head, clean after using every six rolls of paper, or every time after printing 900m.
