Konica KM512 MN Printhead

The Konica KM512 MN Printhead is a robust, shear mode, piezo on-demand print head commonly used in high-quality printing applications. It has 512 nozzles arranged as 256 nozzles per line (two rows) with a nozzle spacing of 70.5 microns and a native resolution of 360 dpi. The droplet size is 14 pico liters, making it capable of delivering fine detail. This printhead supports binary mode and 4-level greyscale mode and operates at a firing frequency of about 7.6 to 12.8 kHz, depending on specific sub-models.

It is compatible with a range of ink types including oil-based, solvent, and UV inks. The print width is approximately 36.1 mm. It is used in various printers such as Agfa Anapurna Mv and Mw models (for varnish and white ink, respectively), HP Designjet 9000s/10000s, Seiko Colorpainter 64s/100s, OCE CS 6060/6100, and other industrial printers.
