Genuine Memjet DuraBolt Industrial Printhead (324.4 mm)
OEM Part Number: Memjet DuraBolt Platform / Bolted Module Array | High-Speed Pigment Thermal Inkjet Single-Pass Print Bar Engine
Product Overview
The Genuine Memjet DuraBolt Industrial Printhead (324.4 mm) is an authentic original equipment manufacturer thermal drop-on-demand (DoD) inkjet print engine designed specifically for high-speed single-pass corrugated packaging, folding cartons, wide web commercial documents, and industrial direct-to-shape lines. Engineered with Memjet’s proprietary silicon MEMS architecture, the DuraBolt module features an expansive active print width of 324.4 mm (12.77 inches). By integrating multiple precision-stitched thermal inkjet dies across a rigid, factory-aligned bolted structural frame, the DuraBolt delivers seamless wide-swath digital jetting without manual die alignment.
Engineered to operate with high-durability aqueous pigment inks, the DuraBolt module incorporates full multi-channel internal ink recirculation across every thermal chamber. This continuous micro-fluidic through-flow prevents pigment settling, purges micro-bubbles, and prevents nozzle dehydration (decap) during machine idle periods. Firing high-density native micro-droplets at native physical resolutions up to 1600 DPI and linear speeds up to 150 m/min (500 ft/min), the DuraBolt module features an onboard ASIC data controller, precision multi-zone thermistors, and integrated fluid manifold couplings to ensure consistent optical density and long service life in heavy industrial production lines.

Key Features & Operational Advantages
- Expansive 324.4 mm Printline: Extra-wide single-module coverage reduces overall module counts across corrugated web lines and folding carton print bars, eliminating stitch-line calibration errors and mechanical registration drift.
- Pigment Continuous Recirculation: Micro-fluidic flow paths circulate aqueous pigment behind every individual firing chamber, eliminating nozzle crusting, preventing pigment agglomeration, and ensuring immediate print readiness after line stops.
- Rigid Factory-Bolted Sub-Assembly: High-precision mechanical datum pins and factory-bolted silicon mounting ensure exact planar flatness and drop-placement alignment across the entire 324.4 mm swath.
- High-Speed Industrial Throughput: Delivers full 1600 DPI imaging at conveyor speeds up to 150 m/min, providing high productivity for digital packaging converting lines without sacrificing fine vector detail or barcode clarity.
CRITICAL TECHNICAL & OPERATIONAL ADVISORY
1. Recirculation Pressure Differential & Negative Meniscus Balancing: The DuraBolt module requires calibrated differential pressure between the supply and return fluidic manifolds while maintaining a strict negative meniscus pressure (-1.5 to -3.0 mbar) at the nozzle plate. Incorrect sub-tank pressure settings will cause nozzle weeping, face flooding, or air ingestion during high-speed firing bursts.
2. Fluid Chemistry Exclusivity: The DuraBolt thermal silicon array is manufactured exclusively for certified Memjet aqueous pigment ink formulations. Never introduce solvent-based inks, oil-based carriers, UV-curable chemistries, or unapproved flush solutions. Contact with non-aqueous fluids will cause irreversible delamination of the thermal heater stack and dissolve structural bonding epoxies.
3. Mandatory ESD Grounding & Power Sequencing: Silicon MEMS heater arrays and high-speed CMOS shift registers are Class 1 ESD-sensitive components. Technicians must wear a grounded ESD wrist strap and work in a static-controlled environment. Always power down the printer engine and discharge power supplies prior to connecting or unseating LVDS data cables or board interconnects.
4. Wet Capping & Silicon Faceplate Maintenance: Never wipe the silicon nozzle plate with dry cloths, paper wipes, or standard foam swabs. Maintenance stations must utilize automated wet-wiping systems with certified cleaning fluid and lint-free microfiber elements. Ensure capping assemblies maintain an airtight, humidified seal during standby to prevent residual pigment dry-out on the orifice array.

*Platform Differentiation Note: The DuraBolt printhead module features an integrated 324.4 mm bolted multi-die format designed strictly for high-throughput aqueous pigment engines. It is physically and electrically distinct from Memjet DuraFlex (A3+ 324 mm single-die modules), DuraLink (222.8 mm modules), and legacy dye-based VersaPass (216 mm) architectures. Ensure host carriage mechanics and fluidic control firmware are configured specifically for the DuraBolt engine 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 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.
