Frequently Asked Questions

My LaserJet 2400 is years old — is its cartridge still a standard item?

Completely standard. The 2400 drinks the Q6511A, the cartridge HP numbers 11A, and it remains a stock line rather than a special order. The label on the cartridge you pull out will confirm the number in one glance.

What comes in the box?

One black cartridge, sealed in its bag, for $45.76. No extras, no kit — the single thing an ageing but willing printer needs to keep working.

How long will 6,000 pages last on a machine this age?

That depends on the work, not the birthday. A 2400 doing a few letters a day can make one 11A last well over a year; the same cartridge in a busy month of reports is spent in weeks. The rating counts pages at standard coverage, and your mix decides the rest.

How do I change it on the 2400?

Raise the top cover, lift the spent unit out, and drop the fresh Q6511A in after rocking it gently and pulling its seal. The design predates fussy mechanisms — if the cover closes flat, the cartridge is seated.

Print is pale on one side of the page only. Cartridge or printer?

One-sided paleness after a rock test often means the toner inside has settled unevenly in its final days — a gentle end-to-end rock that fixes it briefly is practically a signature of an emptying cartridge. If a brand-new cartridge prints the same way, the printer needs attention instead.

What support stands behind it?

A 1-year warranty and 1-year free returns, plus a support team reachable Monday–Friday, 9 AM–5 PM CST — useful when an older machine makes you want a second opinion before ordering.
