KD3008-CF10A Printheads Thick film thermal printhead (11.8 dots / mm) KD3008-CF10A The KD3008-CF10A is a A4-size thick-film thermal printhead, developed mainly for handy printers for personal computers. Applications Plain-paper printers Low speed ticket vendors Measuring terminal printers Features 1) A new pin connector structure greatly reduces the size and weight. 2) A newly developed 144-bit IC levels the strobe partition and reduces the noise level. 3) One rank resistance value of 1250 3% eliminates provides good printing quality on rough paper.
