Ricoh Gen6 Printhead (MH5320) – Standard Cable, 447mm

This Ricoh GEN6 head (MH5340 series) is compatible with UV based inks. The service life of the MH5320/MH5340 is more than double that of the MH5421/MH5441 that preceded it. This is the 4 colour head. The 2 colour head is MH5320.

A minimized 5pl droplet size and improved jetting accuracy yields excellent print quality without graininess. With 1,280 nozzles, this head achieves high-resolution 600dpi printing. Greyscale features a maximum frequency of 50kHz, allowing for increased productivity.

This prinhead is available with a cable (including connector) of either 145mm or 447mm. This printhead has a cable of 447mm and a total length including the printhead of 500mm.

This printhead is made of the two skus: J376-03 (head) and J352-04 (cable 445mm).
