LaserJet 2420

The LaserJet 2420 took the 2400 formula and turned the pace up: a performance step above the base model, in the same compact A4 footprint, for teams whose print queues never really emptied. It uses the family cartridge, the Q6511A — HP’s 11A — and rewards busier owners with the high-yield Q6511X, the 11X, and the maximum-yield Q6511XX. Compatible replacements fill every row of the table below.

Speed changes the toner conversation. A 2420 finishes jobs faster, so the office sends it more jobs, so the monthly page count climbs — and the cartridge that lasted a calm quarter in a 2400 can feel short-lived here without anything being wrong. Owners of this model learn to think in pages per month rather than pages per cartridge, and to buy the yield tier that matches the faster metabolism. The printer is not hungrier per page; it simply prints more pages.

Toner Cartridges for LaserJet 2420

Which cartridge should you buy?

Buy for the pace, not the badge. A 2420 on a genuinely busy desk should start at the high-yield Q6511X and treat the standard Q6511A as the light-duty option; the swap interval is what you are purchasing. Teams that measure output in boxes of paper graduate to the maximum-yield Q6511XX and stop scheduling their month around toner. The standard cartridge still has its place — a 2420 used as a secondary printer, or bought in the ten-pack for a stockroom, where the per-cartridge simplicity wins. Premium and MICR builds round out the shelf for the offices that need those specific things.

Chip, toner and everyday use

Fast printers hide low toner well: output stays bold until late in the cartridge, then fades in a hurry. Let the supplies gauge, not the page quality, time your reorder on a 2420. When the new cartridge goes in, one firm push until it seats, then a couple of test pages, and the machine is back to full pace. Page-yield ratings assume five percent coverage; an office printing full-page reports spends toner faster than the rating implies, on this model or any other. Keep one cartridge ahead of the installed one at all times — on a fast printer, the gap between low and empty is short.

Frequently Asked Questions

Does the 2420 use the same cartridges as the 2400?

Yes, the entire range shares the Q6511A, Q6511X and Q6511XX line. The 2420’s difference is pace, not appetite per page. A cartridge that serves a sibling model serves this one, which keeps mixed offices on a single stocking list.

Why does my 2420 seem to empty cartridges sooner than our 2400 did?

Almost always volume, not defect. The quicker engine attracts more work, and monthly pages rise accordingly. Compare pages printed, not weeks elapsed: if the page counts match the old printer’s, the cartridge is behaving normally and the honest fix is a higher yield tier, not a different brand.

11X or maximum yield for a busy team?

The high-yield Q6511X is the balanced step for most busy 2420s. Choose the maximum-yield Q6511XX when swaps themselves are the disruption — when the printer serves a whole floor, or when the person who changes cartridges is also the person busiest at month-end. Both fit identically; the difference is purely how long each lasts.

What pack sizes does the standard cartridge come in here?

The Q6511A is listed as a single and in two, three, five and ten packs, plus a premium-build five-pack and a MICR single. The high-yield Q6511X comes as a single and in two, three and five packs. Larger packs trade a bigger single order for fewer reorders across the year.
