This head is compatible with UV, Solvent and Aqueous based inks. Specifically, the aqueous ink compatibility and service life of the MH5320/MH5340 is more than double that of the MH5421/MH5441 that preceded it.

* Results obtained using ink and evaluation procedures defined by Ricoh

System compatibility

A new, straightforward alignment method using printhead surfaces enables high precision positioning accuracy and easy alignment. Printhead replacement is simple. In addition to official MH cables, customers may design cables compatible with their application as needed with the existing cable structure.
