PT. Printerhead Wholesaler

The Kyocera KJ4A-AL print head is a high-precision industrial inkjet printhead designed primarily for UV-curable inks or other high-viscosity inks. It features 2,656 nozzles arranged across a print width of 108.25 mm and operates at a maximum drive frequency of 20 kHz, allowing print speeds up to 50 meters per minute. The print resolution is 600 x 600 dpi, and it supports drop volumes of 3, 6, and 13 picoliters for fine, high-quality printing.

This printhead includes an integrated microfilter system to remove ink impurities and a built-in heater to stabilize ink viscosity with temperature changes, ensuring consistent ink flow. The unique ink channel design reduces nozzle failure during extended use. Its dimensions are approximately 200 mm x 25 mm x 58 mm, with a dry weight around 420 grams. The KJ4A-AL is widely used in applications such as label printing, packaging, signage, and graphic printing requiring high-quality UV ink output. It is manufactured in Japan and comes with a manufacturer warranty.

Additionally, it is recommended to change the head cables when installing a new KJ4A-AL printhead to ensure optimal performance. The printhead's optimum ink viscosity range is between 6.0 and 7.0 mPa·s.
