XpertJet PrecisionCore Architecture & I3200-E1 High-Density Core Distinction

The Mutoh DH-41206 Printhead Assembly is an authentic factory-original OEM replacement component engineered for Mutoh’s high-throughput commercial sign production printers: the XpertJet 1641SR Pro and XpertJet 1682SR Pro series equipped with the full-width 8-row MEMS carriage platform. Operating on the industrial Epson I3200-E1 PrecisionCore MicroTFP core (the solvent-passivated "E" derivative), this assembly doubles the active nozzle count of the I1600 series to 3,200 active nozzles across 8 parallel lines. It features reinforced manifold seals and factory encryption parameters tailored to Mutoh's high-frequency drive electronics running MS31 and MS41 eco-solvent inks.

CRITICAL TECHNICAL & SERVICE ADVISORY

1. Transducer Differentiation (DH-41206 I3200-E1 vs. DH-40694 I1600-E1 vs. Aqueous I3200-A1): The DH-41206 uses the 8-row I3200-E1 core with 3,200 nozzles. It is not interchangeable with the 4-row DH-40694 (I1600-E1) printhead or water-based heads (I3200-A1 / DH-40559). Installing an aqueous head into an eco-solvent system will dissolve the internal bonding adhesives within hours.

2. Dual-Head Staggered Calibration (XPJ-1682SR Pro): On dual-head platforms, replacing a printhead requires mechanical slant alignment followed by automated optical registration via Mutoh's integrated DropMaster 2 / FeedMaster sensor calibration or manual alignment in Service Mode to guarantee seamless pass blending.

3. Mandatory Head-Rank ID Calibration: After mechanical installation, the technician MUST enter the alphanumeric Head-Rank ID (printed on the barcode label) via the Mutoh Maintenance Engineer Software (`MSA`). Running without registering the factory voltage rank leads to incorrect drop velocity, satellite misting, and premature piezo actuator failure.

4. Faceplate Maintenance Precautions: Never wipe the delicate orifice faceplate with dry shop wipes or coarse paper towels. Clean only using approved lint-free foam swabs moistened with genuine Mutoh MS31/MS41 cleaning liquid. Regularly inspect and clean the rubber capping station seals and wiper blades to avoid dried solvent ink build-up along the nozzle row.

Condition: 100% Brand New, Genuine OEM Factory-Original Mutoh 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.
