Main Features and Advantages
A worn printhead may cause faded areas, missing dots, vertical lines, or inconsistent image density. Replacing the printhead helps restore sharp text, graphics, photos and barcode printing on SD260 cards.
The printhead is designed as a replacement component for the Datacard SD260 card printer. The SD260 is a 300 dpi direct-to-card printer supporting both full-color and monochrome printing.
The printhead transfers images from the ribbon to the card through thermal printing. A properly functioning printhead helps maintain stable image density and detailed output across repeated card-printing jobs.
A replacement printhead provides a practical solution when an existing printhead becomes worn or damaged. Because the SD260 uses an operator-replaceable printhead, replacement can help return the printer to normal operation without replacing the entire printer.
