Expected page output and replacement cycles
Lexmark calculates page yields for 82K6U and 82K6X cartridges using ISO/IEC 19798 standard coverage testing. High-duty enterprise workflows will experience variations based on coverage area, graphic density, and batch size, with ultra-high yield units drastically extending maintenance intervals for intense colour output.

Selecting capacity and managing stock
If you print heavy text documents and high-volume reports, stocking the 55,000-page 82K6UK0 black cartridge offers the lowest maintenance overhead. If you print marketing collateral with rich photos and graphics, pair it with 82K6U colour toners to prevent frequent replacements. We dispatch genuine Lexmark toner cartridges directly from warehouses in Perth, Brisbane, Sydney, Melbourne, and Adelaide. Free delivery applies on all orders over $99. Every purchase is backed by our full 30-day returns policy.
Pro Tip
When replacing high-capacity toners like the 82K6U series, gently rock the cartridge horizontally five to six times before installation. This evenly redistributes settled toner particles after transit, ensuring smooth, consistent print density from the very first page.
If only one colour has run dry, there's no need to replace the rest - a single Genuine 82K6UK0 cartridge (from $191.11) is the lowest-cost way to keep printing.
For maximum yield, the Genuine 82K6XC0 Cyan Extra High Yield cartridge (from $689.19) offers the lowest cost per page of any option in this range and qualifies for free delivery.
Frequently Asked Questions
Can I mix 82K6X extra high yield and 82K6U ultra high yield toners in the same printer?
Yes, Lexmark CX825 and CX860 printers allow you to mix 82K6X (22,000-page) and 82K6U (55,000-page) cartridges freely across different colour slots without causing calibration or recognition issues.
Why do colour cartridges in this series have a higher cost per page than black?
Ultra-high yield colour cartridges require complex chemical toner formulations to maintain precise colour temperature and adhesion at maximum print speeds, whereas black toner uses single-pigment carbon formulas produced at much higher volume scales.
How does print coverage affect actual enterprise toner lifecycle?
ISO testing assumes 5% coverage per colour. Enterprise printing with heavy background tints, corporate logos, or full-page graphics often increases coverage to 15-20%, which reduces page yields proportionally below the rated 22,000 or 55,000-page maximums.
Is 82K6UK0 the same as 82K6U Black?
Yes, 82K6UK0 is the official Lexmark part number for the 82K6U series Black ultra high yield toner cartridge. The "K" in the part number designates Black, while "C", "M", and "Y" designate Cyan, Magenta, and Yellow respectively.
