Ricoh GEN6 MH5320 New Printhead (Cable: 447mm)

Ricoh GEN6 Printhead (MH5320 Series) – High Precision & Long Life

The Ricoh GEN6 MH5320 series printhead is engineered for UV-based inks, delivering superior print quality and outstanding reliability. With a service life more than twice as long as the previous MH5421/MH5441 models, this printhead ensures long-lasting performance and reduced downtime.

This model is the 2-color version (MH5320), while the 4-color version (MH5340) is also available. Featuring a minimum 5pl droplet size and improved jetting accuracy, it produces smooth, high-resolution prints without visible graininess. Equipped with 1,280 nozzles, the MH5320 achieves a native resolution of 600 dpi, while its grayscale jetting at up to 50 kHz boosts productivity without compromising image quality.

The printhead includes a 447 mm cable (total length 500 mm) and is composed of two parts: J376-03 (head) and J352-04 (445 mm cable).
