Pro Tip
Colour laser printers run internal calibration cycles upon installing new cartridges; replacing all depleted colour toners at the same time prevents repeated automatic alignment routines that consume extra toner.
Match Your Printing Habits to the Right Lexmark 20N30 Toner Cartridge Pack
If all your colours are running low, the 4-Pack 20N30 Genuine (from $483.07) covers every colour in one order and qualifies for free delivery.
If only one colour has run dry, there's no need to replace the rest - a single Genuine 20N30K0 cartridge (from $109.86) is the lowest-cost way to keep printing.
For a high-volume office, buying in bulk cuts the cost per unit further - the 8-Pack 20N30 Genuine (from $956.29) is the equivalent option if you'd rather stick with official ink. This qualifies for free delivery.
Frequently Asked Questions
Can I mix standard 20N30 and high-yield 20N3X cartridges in the same printer?
Yes, you can install a 20N3X extra high yield black cartridge alongside standard 20N30 colour cartridges. The printer tracks remaining toner for each slot independently regardless of cartridge capacity.
Why does colour toner deplete when printing predominantly black documents?
Lexmark laser printers use small amounts of cyan, magenta, and yellow toner during periodic calibration routines to maintain colour accuracy and printhead timing, even if print jobs are set to black and white.
How long can unopened Lexmark 20N30 and 20N3X cartridges be stored?
Genuine unopened Lexmark toner cartridges have a shelf life of up to 24 months when stored flat in a cool, dry area away from direct sunlight and humidity.
Is 20N3XK0 the same cartridge as 20N3X Black?
Yes, 20N3XK0 is Lexmark's exact manufacturer part number for the 20N3X extra high yield black toner cartridge; both refer to the exact same physical product.
