Compatible models and purpose - Developed for CLP-365, CLX-3305, Xpress C410W, C430W, C460FW, C480FW and for MFP 178nw, 179fnw, 150a printers, this replacement fusing unit restores optimal print quality and eliminates fusing-related errors in your compatible device. Fusing technology - The JC91-01079A fusing unit applies controlled heat to melt toner particles so they penetrate deep into paper fibers, delivering clear, smudge-resistant documents with professional print quality that resists fading and smearing. Voltage options - Choose between 110 V (JC91-01079A) or 220 V (JC91-01080A) versions to fit regional power requirements. Ensure you select the correct voltage specification for safe and efficient operation of your printers. Durable construction - Made from high-quality metal, plastic and rubber components, this black fusing unit is built in a standard size for extended service life, reduced maintenance frequency, and consistent performance throughout its operating life. Use scenarios - Office replacement: When prints begin to fade, smear, or show fusing defects, install this unit to restore professional results in everyday documents, invoices, reports, and presentations. - Multi-device environments: In small businesses using several compatible printers, deploy matched JC91-01079A or JC91-01080A units to maintain uniform print quality across devices. - Regional installation: If your facility operates in a specific voltage region, select the corresponding version (110 V or 220 V) to ensure safe, reliable operation and optimal fusing performance.
