Compatible toner for HP LaserJet 2400 series

This two-pack of black toner cartridges replaces HP Q6511A supplies. It fits LaserJet 2400, 2410, 2420 and 2430 models including network and duplex variants. Each cartridge delivers approximately 6000 pages at 5% coverage. The aftermarket units are manufactured to ISO quality standards.

Practical limits of standard-yield cartridges

Standard-yield toner suits moderate print volumes but requires more frequent changes than high-capacity alternatives. The 5% coverage benchmark means dense graphics or full-page text will reduce actual output. Users printing thousands of pages monthly will reorder often and may face higher per-page cost over time.

Upgrade from single OEM cartridges

Buyers replacing single OEM cartridges gain a spare unit and lower unit cost with this twin pack. The jump is worth it when print volume justifies keeping a backup on hand. It does not suit environments needing high-yield capacity or colour output.

Questions about this item

Should I buy the two-pack or a single cartridge for my LaserJet 2420?

The two-pack gives you two 6 000-page black cartridges, so you can replace the empty one immediately and keep a spare on hand.

What does the 6 000-page yield mean for everyday printing on a LaserJet 2430?

It is measured at 5 % coverage; typical office documents with graphics or bold text will use more toner, so expect fewer pages in practice.

Does the Q6511A cartridge use a chip that works with the LaserJet 2400 series?

Yes, the cartridge is built to replace HP Q6511A and fits the 2400, 2410, 2420 and 2430 models without extra steps.
