Xerox WorkCentre 7755/7765/7775 CC Assembly For K CRU (Charge Corotron Assy For Black)

Achieve consistently sharp, professional black text and graphics with the Xerox Charge Corotron Assembly for Black CRU designed for the WorkCentre 7755, 7765, and 7775 models. Built for the Xerox Color 500 series, this component helps maintain peak print quality by delivering precise corona charging throughout the black imaging process. Replacing worn or degraded charge components with a genuine Black CRU ensures reliable toner adhesion, even solid fills, and fewer print anomalies, so your documents look as good on the last page as they do on the first. With this CC Assembly, you’ll experience smoother operation, fewer service calls, and a longer life for your printer’s imaging system, all backed by Xerox’s commitment to performance and compatibility.

• Premium compatibility with WorkCentre 7755/7765/7775 — engineered to integrate seamlessly with the printer’s black charging path in the Color 500 series, ensuring optimal electrical charging and consistent results across diverse jobs and media types. This compatibility minimizes downtime and reduces the risk of misalignment that can occur with third-party substitutes.
• Reliable black image formation — the Charge Corotron Assembly maintains uniform corona charging for blacks, reducing mottling and improving the density of solid black areas in text, logos, and page backgrounds. Expect crisper text, richer blacks, and more faithful reproduction of high-contrast graphics on every page.
• Enhanced print quality and consistency — with precise electrode alignment and controlled current, you’ll see stable black density, fewer streaks, and better overall fidelity from page to page, even across long print jobs or mixed media schedules. The result is professional-grade documents that convey clarity and detail.
• Easy installation and maintenance — designed for straightforward replacement in compatible devices; user-friendly connectors and mounting points make swaps quicker and cleaner, minimizing downtime and the need for specialized tools. A proper installation reduces the likelihood of misfeeds or charging issues that can disrupt workflow.
• Cost-effective, OEM-grade reliability — Xerox-authorized CRU built to meet or exceed original specifications, helping extend printer life and reduce per-page costs. Choosing the Black CRU supports consistent performance and lowers the total cost of ownership over the life of your WorkCentre.
