MH5421F
Ricoh MH5421F is a high-performance aqueous/high-viscosity recirculating printhead in Ricoh's Gen5 series. The 'F' denotes an internal structure and anti-corrosion treatment optimized for aqueous/special inks. Compared to the conventional MH5420 (Gen5 2-color version), the MH5421F has been specially optimized for ink compatibility (particularly with aqueous textile inks and aqueous pigment inks) and internal ink circulation, significantly reducing the risk of clogging and drying of aqueous inks.
