Extra High-Yield Black Toner

This Lexmark 55B1X0E cartridge delivers 20,000 pages of black toner for compatible Lexmark laser printers. It is an original OEM supply designed for consistent image quality and long-life reliability.

Suited for high-volume mono printing

Offices that print thousands of monochrome pages each month will benefit from the extra high-yield capacity. Environments needing colour output or lower page volumes should consider other supplies.

20,000-page yield confirms fit

The decisive specification is the 20,000-page yield at standard coverage. Match this figure to your printer model list — MX431adn, MX431adw, MS431dn, MS431dw — to verify compatibility before purchase.

Questions about this item

How do I install the Lexmark 55B1X0E cartridge in my MX431adn, and what step do people often miss?

Open the front door, pull the old cartridge straight out, shake the new 55B1X0E gently side-to-side to distribute toner, remove the orange sealing tape completely, then slide it in until it clicks — many forget the tape and get blank pages.

What maintenance or replacement will the Lexmark 55B1X0E need after its 20000-page yield?

The cartridge itself is replaced once the 20000-page yield is reached; the printer will prompt you to install a new 55B1X0E — no separate drum or developer unit exists on the MX431adn, MS431dn or related models.

What limit appears first during long print runs with the Lexmark 55B1X0E?

The 20000-page rated yield is the first hard limit; once that volume is printed the toner is depleted and the cartridge must be swapped for a fresh 55B1X0E.
