LaserJet 2400
Introduced in 2004, the HP LaserJet 2400 carried the workgroup torch for small and midsize offices. This A4 monochrome printer balanced speed, print quality, and a compact footprint — the everyday machine for teams that printed constantly.
It uses the HP 11A cartridge (Q6511A), with the high-yield HP 11X (Q6511X) available for heavier volumes. We carry compatible and genuine OEM versions of both.

Frequently Asked Questions
What is the difference between the Q6511A and Q6511X cartridges for the HP LaserJet 2400?
Both the Q6511A (HP 11A) and the Q6511X (HP 11X) fit the HP LaserJet 2400; the X is simply the high-yield version that lasts longer per cartridge. The cartridges are physically interchangeable, so pick whichever matches your print volume.
Should I buy the Q6511A or the Q6511X for my HP LaserJet 2400?
Think about volume: the Q6511A suits a HP LaserJet 2400 that prints a few pages a week, while the Q6511X suits one that works daily. The HP LaserJet 2400 accepts both without any settings change.
Why is my HP LaserJet 2400 printing faded or streaky pages?
Streaks from the HP LaserJet 2400 most often point to low toner in the Q6511A or an unevenly distributed cartridge. Try redistributing the HP 11A cartridge with a gentle rock; if pages stay pale, the HP LaserJet 2400 is due for a fresh Q6511A.
