Ricoh GEN6 Printhead (Cable: 447mm) - MH5320

This Ricoh GEN6 head (MH5320 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 2 colour head. The 4 colour head is MH5340.

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 printhead has a cable of 447mm and a total length including the printhead of 500mm.
