Pro Tip
Verify printer model compatibility before purchasing the 20,000-page 55B6X00 toner. While the standard 55B6000 and 55B6H00 fit all MS331, MS431, and MX431 models, the extra high-yield 55B6X00 cartridge is engineered specifically for MS431 and MX431 models and is not recognized by MS331 printers.

Frequently Asked Questions
Can I use the 55B6X00 extra high-yield cartridge in a Lexmark MS331dn printer?
No. The Lexmark MS331dn printer only accepts 55B6000 standard yield (3,000 pages) and 55B6H00 high yield (15,000 pages) toner cartridges. The 55B6X00 extra high-yield cartridge is restricted to MS431 and MX431 series printers due to firmware specifications.
Do high-yield Lexmark toner cartridges require a different drum unit?
No. All cartridges in this series (55B6000, 55B6H00, and 55B6X00) share the exact same external cartridge housing dimensions and dock seamlessly into the standard Lexmark imaging unit.
How does changing toner cartridge yield affect printing costs?
Upgrading from standard 55B6000 (3,000 pages) to 55B6H00 (15,000 pages) or 55B6X00 (20,000 pages) substantially reduces cost-per-page. High-yield cartridges contain more toner powder in the same physical body, extending replacement intervals during high-volume document printing.
Is 55B6X00 the same as 55B6 X00 or 55B6-X00?
Yes. 55B6X00, 55B6 X00, and 55B6-X00 all refer to the exact same Lexmark extra high-yield Black toner cartridge. Spaces and hyphens are minor formatting variations used by different suppliers, but the physical product and printer fit remain identical.
