This TCT toner cartridge replaces Lexmark OEM number 51B1000 and fits the MS317XX, MS417XX, MS517XX, MS617XX, MX317XX, MX417XX, MX517XX and MX617XX printer families. It is a new aftermarket unit supplied as a single black cartridge. The standard-yield formulation is rated for approximately 2500 pages at 5 percent coverage.

Suitable for offices running the listed Lexmark

Buyers who need a direct replacement for the 51B1000 in any of the compatible MS or MX devices will find this cartridge fits and prints without modification. It is not for users whose printers require a different Lexmark cartridge number or a high-yield variant, nor for machines outside the MS317XX through MX617XX ranges.

Rated yield of 2500 pages at 5 percent coverage

The page-yield figure is the primary specification that determines whether this cartridge matches your volume expectations. At the industry-standard 5 percent coverage the cartridge delivers roughly 2500 pages; actual output will vary with document density and print settings.

Questions about this item

How do I install the 51B1000 cartridge into my Lexmark MX317 and what step do people often miss?

Open the front cover, pull out the old unit, remove the orange protective clip and tape from the new cartridge, shake it gently side-to-side, then slide it firmly into the slot until it clicks; the step most often missed is removing the sealing tape completely.

What maintenance or replacement will the 51B1000 need after its 2500-page yield at 5% coverage?

When prints start to fade or show streaks you simply replace the whole cartridge; there are no separate drums, developers or waste bins to service on this model.

What limit appears first during a long continuous print run with the 51B1000?

The cartridge is rated for 2500 pages at 5% coverage, so the toner supply runs out before any thermal or mechanical limit is reached.
