Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Temperature Toner Fixing: Designed to heat and permanently bond toner onto paper in Lexmark MS321/MS421/MS521/MS622/MX421/MX522/MB2442/MB2338 series printers, ensuring crisp and durable prints.
  • Precision Alignment: Equipped with robust gears and bearings to maintain precise paper alignment during high-volume printing, minimizing misfeeds and ensuring consistent output quality.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a durable aluminum/steel alloy and heat-resistant ABS plastic construction, this fuser unit withstands harsh high-temperature environments while maintaining structural integrity. Its corrosion-resistant materials outlast standard plastic components in humid or industrial settings.*

  • 2. Modular Design for Easy Maintenance

    • With a modular design featuring replaceable parts and standardized connectors, you can swiftly repair or upgrade individual components without replacing the entire unit. This reduces downtime compared to non-modular fuser systems.*

  • 3. High-Temperature Performance Reliability

    • With precision-engineered heating elements and airflow slots, this unit ensures consistent toner fusion at optimal temperatures, supporting fast printing speeds (up to 30 pages/minute) for commercial workloads. Outperforms basic fusers in maintaining quality under continuous use.*

  • 4. Commercial-Grade Scenario Adaptability

    • Designed for high-volume Lexmark printers (e.g., MS621, MX522), this fuser unit handles 24/7 operation demands, minimizing malfunctions in busy office or industrial settings. Ideal for environments requiring uninterrupted output versus home-use alternatives.*

  • 5. Eco-Friendly Compliance Certifications

    • With EPR certifications from Germany and France (EPR_Germany_Packing, EPR_France_Packing), this unit meets strict environmental regulations for recycling and waste management, unlike non-certified competitors.*
