Lexmark C240X10 Black Toner — Extra High Yield

Experience consistently outstanding print quality with the Lexmark Unison Original Extra High Yield Laser Toner Cartridge in Black Pack. Engineered for long-lifecycle reliability, this cartridge delivers crisp text, deep true blacks, and uniform grayscale across high-volume workloads. Built around Lexmark’s innovative Unison™ toner technology, it maintains exceptional image integrity from the first page to the last, even as your color output scales or your business documents become more demanding. The Black Pack is designed for offices that print in bulk and demand predictable results, reduced downtime, and a smarter, more sustainable printing solution. Whether you’re preparing professional reports, invoices, contracts, or customer communications, this cartridge helps you present a polished, legible, and trustworthy impression with every page.

• Exceptional print quality and consistent performance. Unison™ toner technology is a breakthrough formulation that synchronizes toner, drum interaction, and fusing within Lexmark printers. The result is consistently sharp type, clean lines in graphics, and uniformly dark blacks across text and dense areas. With this cartridge, you won’t see fading or uneven density as pages accumulate; you’ll enjoy reliable readability on every document, from executive summaries to marketing materials. The consistency reduces wasted reprints and eliminates the guesswork that often accompanies high-volume printing.
• Extra high-yield design for fewer replacements. This Black Pack is purpose-built to deliver an extended page yield, helping you minimize interruptions in busy workflows. By reducing the frequency of cartridge changes, your team spends more time printing and less time swapping supplies. The higher yield profile also translates into lower total cost per page, making it a smart choice for multi-user offices, administrative departments, and departments with heavy day-to-day printing needs. The long-life cartridge is engineered to withstand frequent print runs without compromising image quality, so longer jobs stay consistent from start to finish.
• Shake-free print system for cleaner, more reliable outputs. Lexmark’s shake-free print system prevents toner movement inside the cartridge, which minimizes the risk of smudges, streaks, or misfeeds during high-speed or high-volume printing. The result is smooth, even coverage on both text and graphics, with fewer occasional inconsistencies that can occur in other toner systems under demanding print conditions. This feature is especially valuable in busy offices where throughput matters as much as page accuracy, helping you maintain a professional, printer-ready appearance on every page.
• Designed for sustainability and responsible use of resources. The Unison toner family is part of Lexmark’s commitment to eco-friendly printing. The Extra High Yield cartridge is optimized to maximize pages per cartridge, reducing packaging waste and the frequency of replacements. Lexmark’s sustainability programs support responsible recycling and end-of-life management, making it easier for businesses to align printing activities with corporate environmental goals. In addition, the cartridge’s efficient toner usage helps you get more life out of your printer’s consumables while maintaining performance standards that matter to your team and clients alike.
• Easy installation, compatibility, and user-friendly handling. The Black Pack is designed for straightforward, drop-in replacement in Lexmark printers that support Unison toner. With precise alignment and secure sealing, installation is quick and hassles are minimized—so IT staff and office users alike can swap cartridges with minimal downtime. The packaging and protective seals are crafted to preserve toner quality until use, ensuring you get the performance you expect from the moment you install the cartridge. This ease of use makes it a preferred option for shared printers and offices that rely on smooth, predictable supply chains for daily operations.
