Product Overview
The Genuine Ricoh MH5440 (Gen5) is the 4-color version of Ricoh’s widely used Gen5 industrial inkjet printhead series, offering high-resolution quality and multi-ink flexibility. Featuring 1,280 nozzles arranged in four staggered rows of 320 nozzles, it delivers native 600 dpi resolution with excellent image quality. Multi-drop greyscale technology provides variable droplet volumes starting from 7 pL (binary) up to approximately 21 pL* (practical range; official capability extends higher depending on ink), enabling smooth tonal reproduction across 4 grey levels. With jetting frequencies of 30 kHz in binary mode and 20 kHz in greyscale mode, the MH5440 balances quality and productivity. Fully compatible with UV, solvent and aqueous inks, this head uses isolated ink paths supporting up to four colors and includes an integrated heater and thermistor for stable viscosity control. Its stainless-steel construction and proven durability make it a popular choice for multi-color industrial systems used in labels, packaging, textiles and wide-format graphics.

Technical Precision & Operational Advisory
- Electrostatic Discharge (ESD) Protection: Always wear a properly grounded ESD wrist strap when handling the printhead. Piezo electronics are highly sensitive to static electricity.
- Power Isolation Warning: Completely power off the printer and disconnect the main power supply before connecting or disconnecting the FFC ribbon cable or fluid lines.
- Cable Replacement Protocol: It is strongly recommended to replace the head cable with a new genuine Ricoh cable when installing a new printhead to ensure reliable signal transmission.
- Fluid System Preparation: Thoroughly flush the ink system with the appropriate cleaning fluid for the ink type (UV, solvent or aqueous) before first use. Only use inks within the recommended viscosity range (10–12 mPa·s).
- Temperature Control: Utilize the integrated heater and thermistor to maintain optimal ink temperature and viscosity for consistent droplet formation during production.
