JV400-SUV Hybrid Solvent-UV Gen5 Architecture Notice

The Mimaki M014400 / MP-M014400 Printhead Assembly is the authentic OEM industrial drop-on-demand replacement module engineered exclusively for Mimaki’s solvent-UV hybrid roll-to-roll printers: the JV400-130SUV and JV400-160SUV. Operating on the Ricoh Gen5 (MH5420 core) architecture, this specialized head features internal chemical passivations designed to withstand the combined chemical aggression of aggressive solvent diluents and reactive UV photoinitiators found in Mimaki SU100 hybrid ink chemistry.

CRITICAL TECHNICAL & SERVICE ADVISORY

1. Platform Specificity Across the JV400 Series (SUV vs. LX): The M014400 is engineered specifically for Mimaki JV400-SUV models (SU100 solvent-UV ink). Do NOT cross-install this printhead into JV400-LX latex printers, which require M022651 / M014384. While both use the Ricoh Gen5 MH5420 form factor, internal manifold materials and voltage drive waveforms are configured strictly for their respective fluid formulations.

2. Staggered Carriage Slant & Registration Calibration: In the 4-head staggered JV400-SUV carriage, replacing a printhead requires optical mechanical slant alignment followed by service mode electronic registration (`[#] ADJUST` > `HEAD SP-ADJUST` and `SLANT ADJUST`) to align all 4 heads across forward and reverse scan passes.

3. Mandatory Head ID Voltage Registration: After physical mounting and cable attachment, the technician MUST enter the alphanumeric Head ID value (printed on the head barcode label) into the printer’s Service Mode menu (`[#] PARAMETER` > `HEAD ID`). Running without registered voltage parameters causes drop deflection, ink misting, or premature piezo fatigue.

4. Faceplate Maintenance Precautions: Never wipe the nozzle faceplate with dry shop wipes or coarse towels. Clean only using approved lint-free foam-tipped swabs moistened with genuine Mimaki SUV cleaning liquid. Regularly inspect and clean the rubber capping station seals and wiper blades to avoid cured resin buildup along the nozzle orifices.

Condition: 100% Brand New, Genuine OEM Factory-Original Mimaki / Ricoh Industrial Replacement Printhead Assembly in sealed factory packaging with factory shipping preservation fluid intact.

Manufacturer Warranty: Covered under standard OEM parts limited warranty against material and manufacturing defects out-of-box prior to ink introduction. No warranty applies once active ink or flush fluid has been introduced into the micro-fluidic chambers, or if damage results from head strikes, media jams, electrostatic discharge, or improper cable seating.

Return Policy: Precision industrial electronic component. Unopened, factory-sealed boxes with intact tamper-evident seals are eligible for standard commercial return. Once the vacuum seal is broken, protective nozzle tape removed, or the head mounted onto a carriage frame, returns cannot be accepted due to fluid priming, static risk, and electrical contamination hazards.
