Technology by field
The RICOH MH5422/5442 is the next advanced performance print head in the “RICOH MH5420/5440” and “RICOH MH5421/5441” family of print heads.
With 1,280 nozzles configured in 4 x 150npi rows, native droplet of 7pl, and enhanced specification for jetting accuracy and velocity resulting in higher and reproducible print quality. RICOH MH5422/5442 offers optimum jetting performance at a new maximum frequency level of 50kHz, enabling increased productivity in binary mode.
*Where RICOH MH5442 is used.
This head is compatible with UV, Solvent and Aqueous based inks. Specifically, the aqueous ink compatibility and service life of “RICOH MH5422/MH5442” is more than double that of the “RICOH MH5421/MH5441”.
*Results obtained using ink and evaluation procedures defined by Ricoh
RICOH MH5422/MH5442 has enhanced non-wet coating provides a more durable nozzle surface for continued robust printing including print head maintenance.
*Result obtained using ink and evaluation procedures defined by Ricoh
A new, straightforward alignment method using printhead surfaces enables high precision positioning accuracy and easy alignment.
RICOH MH5422/MH5442 has a detachable I/O cable design.
