Genuine Memjet DuraLink Industrial Single-Color Printhead (2.1 pL / 222.8 mm)
OEM Part Number: Memjet DuraLink Series / Single-Channel Modular Architecture | High-Speed Pigment Thermal Inkjet Modular Single-Pass Print Bar Engine
Product Overview
The Genuine Memjet DuraLink Single-Color Printhead (2.1 pL / 222.8 mm) is an authentic original equipment manufacturer thermal drop-on-demand (DoD) inkjet print engine engineered specifically for heavy industrial production, continuous high-speed digital web presses, wide-format corrugated lines, and commercial publishing platforms. Designed as a scalable modular building block, DuraLink printheads can be seamlessly stitched and tiled across custom-width print bars spanning from 222.8 mm up to 2.5 meters wide, providing digital press integrators with industrial throughput and modular serviceability.
Featuring an active print swath width of 222.8 mm (8.77 inches) housing 70,400 active addressable nozzles dedicated to a single dedicated fluid channel (5x nozzle redundancy across 10 interleaved rows), the DuraLink printhead delivers continuous high-speed jetting with exceptional line reliability. The module operates with light-fast, water-resistant aqueous pigment inks and incorporates continuous micro-fluidic recirculation swept directly across every thermal chamber. Firing precision 2.1 picoliter (pL) native micro-droplets at native physical resolutions up to 1600 × 1585 DPI at web speeds up to 204 m/min (668 ft/min), DuraLink combines high optical density with thermal durability for high-volume 24/7 printing operations.

Key Features & Operational Advantages
- Modular Scalable Print Bar Design: Individual 222.8 mm modules can be stitched together into seamless custom print bars spanning up to 2.5 meters wide, allowing field replacement of single modules without discarding entire print bar assemblies.
- 5x Redundant Nozzle Matrix (70,400 Nozzles): With 10 rows dedicated exclusively to a single ink channel, DuraLink provides 5 physical nozzles per pixel column. If an individual nozzle is blocked by debris, automated fallback algorithmically fires adjacent redundant nozzles, preventing visible white streaks during live production.
- Continuous Through-Chamber Recirculation: Rapid fluid flow constantly circulates directly behind every firing nozzle, purging micro-bubbles, preventing pigment settling in opaque formulations, and extending nozzle decap times during press idle.
- High Linear Web Velocity (204 m/min): Optimized thermal drive electronics achieve industrial speeds up to 204 m/min (668 ft/min), matching conventional flexo/offset line speeds on corrugated board, paper webs, and commercial packaging lines.
CRITICAL TECHNICAL & OPERATIONAL ADVISORY
1. Recirculation Pressure Differential & Negative Meniscus Balancing: The DuraLink module requires precision differential pressure regulation across supply and return ink ports while strictly preserving negative meniscus pressure (-1.5 to -3.0 mbar) at the silicon faceplate. Incorrect pressure balancing will immediately result in nozzle weeping, face flooding, or de-priming air ingestion during high-frequency firing bursts.
2. Fluid Chemistry Exclusivity: The DuraLink thermal silicon array is manufactured exclusively for certified Memjet aqueous pigment ink formulations. 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 engine is fully powered down and power supplies are discharged before mating or unseating PCIe/LVDS 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 stations must utilize cleanroom-grade wet-wiping microfiber rollers charged with genuine Memjet maintenance fluid. Ensure capping stations maintain an airtight, humidified seal during standby to prevent residual pigment crusting at the micro-nozzle orifices.

*Platform Differentiation Note: The Memjet DuraLink printhead is a single-color, high-redundancy modular unit (70,400 nozzles/module, 222.8 mm width) designed for stitched multi-head print bars. It is fundamentally distinct from the 4-color DuraFlex series (A4 222.8 mm and A3+ 324.4 mm CMYK monolithic heads), DuraBolt (wide 324.4 mm bolted arrays), and legacy dye-based VersaPass (216 mm) systems. Confirm module part configuration and print bar controller firmware prior to 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 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.
