Lexmark MX431adn Toner Cartridges
Your Lexmark MX431adn uses the Lexmark 55B6000, 55B6H00 and 55B6X00 toner cartridge series. The Lexmark MX431adn is a compact monochrome laser multifunction printer built for fast, high-volume business document output. Ink Depot has been supplying reliable printer consumables for this model since Aug 2020. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance. Moving from standard 55B6000 cartridges to high-yield 55B6H00 or extra high-yield 55B6X00 options significantly reduces replacement cycles during heavy document workflows.
Expected Page Output and Replacement Cycles
Lexmark determines monochrome toner yields using standard ISO/IEC 19752 coverage testing. For high-volume office environments, selecting high-capacity toners like the 55B6H00 or 55B6X00 dramatically lowers per-page printing costs while keeping replacement downtime to a minimum.

Pro Tip
If your business relies on continuous batch printing, stocking an extra 55B0ZA0 imaging unit alongside your high-yield toners ensures zero downtime when the long-life drum reaches its end-of-life cycle.
Frequently Asked Questions
Is the 55B0ZA0 imaging unit included with the toner cartridge, or sold separately?
The 55B0ZA0 is a separate imaging unit rated for up to 40,000 pages, independent of the 55B6000, 55B6H00, or 55B6X00 toner cartridges. While toner cartridges are replaced as toner depletes, the imaging unit lasts through multiple toner cycles before requiring replacement.
Can I install a high-yield 55B6H00 or 55B6X00 toner in the MX431adn if it came with a standard 55B6000?
Yes, all 55B series toners share the same physical outer dimensions and fit into the exact same slot in your Lexmark MX431adn printer. High-yield and extra high-yield cartridges simply contain a higher volume of toner powder.
How does choosing extra high-yield toners impact overall printing costs in high-volume environments?
Selecting 55B6X00 extra high-yield toners provides a significantly lower cost-per-page compared to standard 55B6000 cartridges. This yields lower total operational expenditure for high-volume offices while drastically reducing cartridge handling and packaging waste.
