Lexmark 75M2XK0 Extra High Yield toner cartridge, black, 20,000 pages

Page yield tells you how many pages a cartridge prints on average. The real figure depends on how much toner each page needs: plain text uses less than dense tables, logos or grey backgrounds. Extra High Yield is Lexmark's label for a higher-capacity cartridge, so replacements come around less often and less time goes into keeping the printer running.

The product name marks this cartridge as original, and the producer is Lexmark rather than a third-party maker. The code 75M2XK0 is the most reliable way to find the right cartridge, because one printer series can have several variants with different capacities or programmes. The cartridge weighs 0.98 kg.

The abbreviation Rtn in the supplier name and the LCCP and LRP markings in the product name refer to Lexmark's cartridge return and collection programme. Cartridges like this are intended to be sent back to the manufacturer for recycling once empty, rather than ending up in household waste. The exact programme terms are not described in the manufacturer data for this item.

The manufacturer data contains no separate list of compatible printers. The supplier has named the item Lexmark CS632, CX635 Blk Rtn 20K Cartridge, but that is the supplier's product name, not a compatibility list confirmed by the manufacturer. Before choosing, compare the code 75M2XK0 with the supply code shown in your printer manual or printer menu.

Offices and companies where a Lexmark printer turns out a lot of black text every day: invoices, contracts, reports and dispatch notes. The large yield means fewer replacements and a smaller stock on the shelf. It also suits IT administrators who look after a printer fleet and prefer used cartridges to go back to the manufacturer through the return programme.
