This Ricoh MH5320 printhead (GEN6 series) comes with a 447 mm cable and is designed for use in a wide range of UV printers. It is fully compatible with UV-based inks. Compared to the previous MH5421/MH5441 models, the MH5320/MH5340 series offers more than double the service life.

The MH5320 is a 2-color head, while the MH5340 version supports 4 colors.

Thanks to its minimized 5 pl droplet size and improved jetting accuracy, the printhead delivers excellent image quality without visible grain.

Equipped with 1280 nozzles, it supports high-resolution 600 dpi printing. Productivity is further enhanced with a maximum grayscale frequency of 50 kHz.

The unit includes a 447 mm cable, giving a total assembly length of 500 mm including the printhead.

This model is supplied under two SKUs:

J352-04 (445 mm cable)
