Why choose the genuine Lexmark 77L20K0 toner cartridge
The 77L20K0 is a genuine Lexmark toner. The powder is matched to the fuser and speed of these printers: sharp text, even solids, proper fusing from the first page, and a cartridge recognized immediately (levels shown, no error message).
When to replace it
The printer shows a message when the part's counter reaches end of life (Supplies status or Reports menu). Replacing it then avoids downtime and wear on other parts.
Printers compatible with the 77L20K0
The list of compatible printers is not available for this reference. Check the reference of your current consumable in the printer's manual or menu: it must match 77L20K0 exactly.
If in doubt, send us the exact model of your printer and we will confirm compatibility.
Installation
Tool-free replacement: open the cover, remove the used cartridge, take the new one out of its bag, rock it gently to distribute the toner, remove the protections, then insert until it clicks. The printer recognizes the cartridge. The used cartridge is recycled through the manufacturer's take-back program or your local collection.
Use and tips
Order the 77L20K0 at the "Low" alert: the printer keeps printing until the replace message, but a cartridge in reserve avoids stopping at the wrong moment.
Store the cartridge in its packaging, flat, away from light and humidity, and unpack it only when installing. Genuine cartridges preserve the printer's warranty.
