OEM Wide-Format Water-Based Component
Original Mutoh DE-49732 DX2 Colour Printhead Assembly
OEM Part Number: DE-49732 / MY-49732 (Cross-Ref: Epson F055090 / Mimaki IH47V / Roland 22805318) | MicroPiezo DX2 3-Line Drop-on-Demand (DoD) Water-Based Aqueous Colour Printhead
Classic DrafStation & Falcon Series DX2 Architecture Notice
The Mutoh DE-49732 Printhead Assembly (engineering cross-reference MY-49732 / Epson F055090) is an authentic OEM replacement module engineered specifically for Mutoh’s classic wide-format aqueous CAD, proofing, and signage plotters: the DrafStation RJ-800, RJ-4000, RJ-4100, RJ-6000, and RJ-6100 series. Operating on the classic MicroPiezo DX2 Colour architecture, this unit integrates 3 independent fluid manifolds with 31-pin dual ribbon connections, passivated exclusively for aqueous dye, water-based pigment, and textile sublimation ink chemistries.
Product Overview
The Original Mutoh DE-49732 DX2 Colour Printhead is an industrial drop-on-demand (DoD) piezoelectric replacement component designed for precision architectural line drawings, GIS maps, photographic reproductions, indoor trade show graphics, and transfer sublimation. Working in tandem with the dedicated DX2 Black head on dual-carriage models (or deployed across multi-head setups in 6-color RJ-6000 presses), this colour assembly provides distinct fluid pathways for three separate color channels within a single chassis.
Featuring 96 active addressable nozzles partitioned across 3 independent linear rows (32 nozzles per row), the DX2 Colour architecture delivers native optical resolutions up to 720 DPI (and 1440 DPI multi-pass modes). Delivering consistent droplet geometry and acoustic pulse stability, this head restores sharp line definition, clean text edges, and smooth gradient fills across coated bond papers, proofing media, and banner films.

Key Features & Operational Advantages
- Classic 3-in-1 Colour Manifold: Consolidates 3 discrete color lines (typically Cyan, Magenta, Yellow) into a single compact housing, preserving tight mechanical alignment between channels.
- Aqueous Fluidic Passivation: Optimized for high-surface-tension water-based inks, preventing chamber foaming, de-priming, and drying during long technical CAD printing shifts.
- Cross-Platform Compatibility: Serves as the factory OEM replacement across legacy Mutoh, Roland Hi-Fi JET, Mimaki JV2, and Kodak wide-format printers using DX2 color technology.
- Direct Drop-In OEM Fitment: Built to exact factory dimensional tolerances, restoring original droplet trajectory and carriage height clearance without mechanical modifications.
CRITICAL TECHNICAL & SERVICE ADVISORY
1. DX2 Colour vs. DX2 Black Differentiation: The DE-49732 is the Colour (3-channel / 3-nipple) assembly. It is not interchangeable with the DX2 Black (1-channel / single-nipple) printhead (Mutoh DE-49731 / DF-43988). Ensure you are replacing the correct carriage position prior to unpacking.
2. Strictly Aqueous / Non-Solvent Notice: This head is engineered exclusively for water-based dye, pigment, and sublimation inks. Never introduce eco-solvent, mild-solvent, or UV inks into this assembly. Solvent carriers will dissolve internal adhesives, causing cross-channel leaks and permanent actuator failure.
3. FFC Ribbon Cable Inspection & Replacement: Always inspect and replace flat flexible data cables (FFC) during installation. DX2 driver circuits on older mainboards are highly vulnerable to short circuits caused by worn, frayed, or ink-contaminated ribbon pins.
4. Damper & Cap Top Servicing: Replace old dampers and service the rubber capping station seals concurrently. Dried ink residue on aged cap tops prevents effective vacuum pulling and leads to immediate nozzle dropout on newly installed heads.

Condition: 100% Brand New, Genuine OEM Factory-Original Mutoh / Epson replacement printhead assembly in sealed factory packaging with 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.
