Lexmark 521H High Yield Black Toner

This genuine Lexmark cartridge delivers up to 25,000 pages of black output for the MS710, MS711, MS810, MS811 and MS812 series printers. It is supplied as a single pack for offices that need consistent, high-volume monochrome printing.

Return Program limits reuse and refill options

The cartridge belongs to the Lexmark Return Program, which means it is licensed for a single use and must be returned to Lexmark after depletion. This restriction prevents third-party refilling and stops the cartridge from being used in non-Lexmark devices.

Straightforward slot-in installation

Installation consists of opening the printer front cover, removing the old unit and sliding the new cartridge in until it clicks. The most common issue occurs when the protective seal or tape is not fully removed, which can cause light prints or error messages.

Questions about this item

Should I pick the 521H high-yield cartridge or a standard-yield version for my Lexmark MS810?

The 521H delivers 25000 pages, so it suits heavy printing on the MS810; a standard cartridge would need replacing more often.

What does the 25000 page yield mean for daily use on an MS711?

At five percent coverage it equals roughly 25000 printed pages; heavier graphics or dense text will reduce the actual count.

Does the 521H work with the Lexmark MS812 series and is there any firmware restriction?

Yes, the cartridge is listed for MS812 as well as MS710, MS711, MS810 and MS811 models with no extra firmware step mentioned.
