Two-Pack Black Toner for Lexmark X642 X644 X646

This SuppliesMax two-pack replaces Lexmark X644H21A cartridges and fits the X642e X644e X646e families plus related MFP models. Each black cartridge yields approximately 21000 pages at five percent coverage. The set suits offices that run high-volume monochrome print jobs on supported 110V printers sold in the U.S.

Drop-In Installation With Standard Handling

Cartridges install like the OEM equivalents: open the front cover, remove the old unit, shake the new cartridge gently, pull the seal tape, and slide it in until it clicks. The most common issue is forgetting to remove the full length of sealing tape, which causes blank streaks on the first pages. Firm seating and a clean corona wire area prevent repeat jams.

21000-Page Yield at Five Percent Coverage

The rated yield of 21000 pages per cartridge at 0.05 coverage is the figure that determines whether this pack matches your print volume. Buyers who need colour output or MICR toner should look elsewhere. Printers outside the listed Lexmark X642 X644 X646 series are not supported.
