OEM Replacement Component
Genuine Memjet DuraFlex A3+ 4-Color Single-Die Printhead (324.4 mm)
OEM Part Number: Memjet DuraFlex A3+ Module / 4-Channel CMYK | Monolithic Silicon MEMS Thermal Inkjet Single-Pass Print Engine
Product Overview
The Genuine Memjet DuraFlex A3+ 4-Color Printhead (324.4 mm) is an authentic original equipment manufacturer thermal drop-on-demand (DoD) single-pass inkjet print engine engineered specifically for entry-to-mid-tier industrial packaging, label production, commercial envelope presses, and folding carton converting. Built on Memjet’s monolithic silicon MEMS architecture, the DuraFlex A3+ printhead integrates a continuous 324.4 mm (12.77 inches) active print swath housing 40,960 active nozzles into a single unified die structure, eliminating die-to-die mechanical alignment challenges and seam calibration errors across the full A3+ media path.
Engineered for full process color from a single compact module, the DuraFlex printhead delivers 4 independent fluid channels (CMYK or custom 4-channel configurations) with dual-row nozzle redundancy per color channel. Operating with Memjet's light-fast, water-resistant aqueous pigment inks, the module features complete internal fluid recirculation through every thermal firing chamber, preventing pigment sedimentation, purging micro-bubbles, and extending nozzle decap times during production idle. Firing uniform 2.1 pL native micro-droplets at native physical resolutions up to 1600 × 1600 DPI, it supports web speeds up to 45 m/min (150 ft/min), making it a compact, high-efficiency engine for modern digital printing machinery.

Key Features & Operational Advantages
- Monolithic 324.4 mm Continuous Silicon Die: Spanning the entire A3+ printing width on a single piece of silicon, DuraFlex eliminates the need to align multiple individual heads, preventing color-to-color shift, mechanical stitch lines, and pass-to-pass calibration banding.
- Full 4-Color (CMYK) Single-Module Architecture: Emits Cyan, Magenta, Yellow, and Black from one integrated print engine, substantially reducing printer build volume, carriage weight, and chassis complexity compared to single-color modular print bars.
- Dual-Row Redundant Nozzle Layout: Every color channel includes dual interleaved nozzle rows (10,240 nozzles/color), providing automated nozzle redundancy to substitute inactive channels and preserve clean output across long production runs.
- Continuous Through-Chamber Recirculation: Constant fluid sweep behind every thermal firing chamber prevents pigment sedimentation, purges micro-bubbles, and keeps high-opacity pigment ink ready to fire without frequent mechanical purge cycles.
CRITICAL TECHNICAL & OPERATIONAL ADVISORY
1. Recirculation Pressure Differential & Meniscus Stability: The DuraFlex module requires precision-controlled differential pressure between its supply and return ink loops while maintaining a strict negative meniscus pressure (-1.5 to -3.0 mbar) at the silicon faceplate. Incorrect pressure balancing will immediately cause fluid weeping, cross-color contamination in the manifold, or air ingestion into the thermal chambers.
2. Fluid Chemistry Exclusivity: The DuraFlex silicon array is manufactured exclusively for certified Memjet aqueous pigment inks. Under no circumstances should the module be filled or flushed with solvent, eco-solvent, oil-based, or UV-curable chemistries. Exposure to non-aqueous carriers will dissolve silicon bonding adhesives and permanently destroy the thermal heater stack.
3. Mandatory ESD Grounding & Power Sequencing: Silicon MEMS heater arrays and high-speed CMOS driver logic are Class 1 ESD-sensitive components. Technicians must wear a grounded ESD wrist strap and work on a static-dissipative work mat. Always ensure the printer is fully powered off and power supply rails are discharged before mating or disconnecting high-density data and power interconnects.
4. Wet Capping & Microfiber Maintenance: The silicon nozzle faceplate must never be wiped with dry cloths, foam swabs, or paper towels. Automated maintenance systems must use cleanroom-grade wet-wiping microfiber rollers charged with genuine Memjet maintenance fluid. Ensure the capping station maintains an airtight, high-humidity seal during standby to prevent pigment crusting at the micro-nozzle orifices.

*Platform Differentiation Note: The DuraFlex A3+ module features a single continuous 324.4 mm silicon die configured for 4-channel CMYK printing. It is fundamentally distinct from Memjet DuraLink (single-color modular print bars, 222.8 mm), Memjet DuraBolt (high-speed multi-die bolted arrays), and legacy Memjet VersaPass (dye-based 216 mm A4 architecture). Verify the host engine controller firmware and fluid delivery module type before installation.
Terms, Warranty & Customer Protection
Condition: 100% Brand New, Unopened Factory Original Genuine OEM Component in Factory-Sealed Static-Shielding Packaging with Factory Storage Preservation Fluid Intact.
Warranty Scope: Covered by standard manufacturer DOA replacement protection against electrical continuity failures, open thermal heater elements, and physical manufacturing defects upon initial arrival. Operating lifespan and nozzle firing health are governed by ink degassing quality, certified aqueous pigment ink usage, closed-loop pressure stability, and adherence to factory maintenance protocols.
Return Policy: Precision industrial electronic consumable. Due to sensitivity to electrostatic discharge, internal fluid priming requirements, and cross-contamination risks once unsealed, components that have been removed from their static-shielding bag, filled with ink, flushed with solvents, or energized cannot be returned or restocked under standard commercial terms. Please confirm your printer engine model and fluid system compatibility with technical support prior to unsealing.
