4. Operation
The R37901900 printhead functions as an integral part of the SATO CL4NX Plus thermal label printer. Once correctly installed, its operation is managed by the printer's internal software and hardware. The printhead heats specific elements to transfer ink from a ribbon (thermal transfer printing) or directly activate heat-sensitive paper (direct thermal printing), creating the desired image or text.
Ensure your printer drivers are up-to-date and that you are using appropriate label media and ribbons (if applicable) for optimal performance and printhead longevity.
