Printheads
Thick film thermal printhead (8 dots / mm)
KD2008-CF10A
The KD2008-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 1000 3% eliminates provides good printing quality on rough paper.
