Frequently Asked Questions

What does the Q6511XX code signify?

The maximum-yield version of this cartridge family. The Q6511XX — sold as the HP 11XX — is rated at 18,000 pages, the longest rated life in its line, and this single unit is $45.41. The double X is the identity to match: check the stamp on the cartridge you remove, and if it reads Q6511XX, this is the same supply.

How far does 18,000 pages stretch in a working office?

On a machine like the LaserJet 2420 carrying a department's daily output, it is a genuinely long interval — the sort of cartridge that is fitted, forgotten, and rediscovered at a stock check months later. The rating is based on standard text coverage, so graphics-heavy work shortens it, but the headroom is the point: this is the deepest reservoir the platform takes.

Does a cartridge this full behave any differently?

In fitting and printing, no — it installs exactly like any other cartridge in this family and the printer treats it the same way. The difference is purely in how rarely you repeat the job. Near its end it fades like any cartridge, and the same gentle side-to-side rock recovers the last settled toner.

Is there a drum to think about alongside it?

No separate drum exists on this platform; the imaging drum is built into the cartridge, so an 18,000-page unit also carries an imaging surface rated for that full service life. One part covers the whole interval — nothing else to buy at any point during it.

What guarantee backs it?

A 1-year warranty and 1-year free returns, with the terms on our shipping and returns page. We ship from warehouses in Illinois, Pennsylvania, Georgia and California, and our support team is staffed Monday through Friday, 9 AM to 5 PM CST should anything about the cartridge need attention.

Who should choose the maximum-yield version?

The office whose printer is both busy and inconvenient to attend — a remote site, a shared machine in another department, a workhorse nobody owns. When every cartridge change involves someone's time and a journey, the longest available interval is worth more than any other feature.

About This HP 11XX Cartridge

This single compatible Q6511XX is the maximum-yield entry for the 2420 platform in our HP toner cartridges range: the deepest toner reservoir this family accepts, rated at 18,000 pages, for printers whose ideal maintenance schedule is 'almost never'. Fit it and let the machine get on with its year.

One part number covers the range: LaserJet 2420d, LaserJet 2420dn, LaserJet 2420n, LaserJet 2430, LaserJet 2430dtn, LaserJet 2430n and LaserJet 2420 all take the 11XX (Q6511XX). Round out the picture with the high-yield 11X (Q6511X) single cartridge and the standard-yield 11A (Q6511A) single cartridge, both listed for this platform.
