Cool Toner Compatible Toner Cartridge Set 507X

If you want to replace a full set of color toner at once, this four-cartridge pack is a different kind of purchase from buying only the color that has run out. It includes one black CE400X cartridge and three color cartridges, intended for specific HP LaserJet Enterprise and Pro models. The stated yields are substantial for routine office printing, but the cartridge codes in the included-set details do not perfectly match every code in the compatibility wording, so matching the cartridge number in your printer matters.

Technical details

The pack contains one CE400X black toner cartridge and one each of CE401A cyan, CE402A yellow, and CE403A magenta. The listed yields are up to 11,000 pages for black and up to 6,000 pages per color cartridge, measured at 5% coverage on Letter or A4 paper. Those figures are reference estimates, not a promise for every job: pages with large color areas, graphics, or heavy text coverage can use toner faster.

This is a compatible replacement set, not a claim that the cartridges are made by the printer manufacturer. The description calls out 507X toner and also lists CE401X, CE402X, and CE403X among compatible codes, while the actual included color cartridges carry A suffixes. That distinction is worth taking seriously if you are replacing a single cartridge rather than stocking a complete set.

Everyday compatibility

The listed printer families include HP LaserJet Enterprise 500 Color M551 models, MFP M570 models, and MFP M575 models, along with Enterprise 500 Color Flow MFP 575c. The description names models such as M551n, M551dn, M551xh, M570dn, M570dw, M575f, and M575c, it also refers to M575dn elsewhere. Since the model list and cartridge-code wording are not fully consistent, match your exact printer model and the code on the cartridge you are removing before choosing this set.

A solid pick if your listed printer needs all four colors replenished and you want black and color toner in one order. If only cyan has run out, a four-pack may leave you storing cartridges you do not need yet. It might not be a great match if your printer is outside the named models or its cartridge label does not align with the included CE codes.

Usage tips

Before installing, compare the cartridge numbers on the new set with the ones specified for your printer, especially the A- and X-suffix color codes. Keep the packaging until you have confirmed the cartridges fit and the printer recognizes them. For a typical office run, the set is suited to handling black documents alongside color charts, presentations, or handouts without buying each color separately. If your work consists mostly of dense, full-page color, the stated page yields may not reflect how long the toner lasts in your day-to-day printing.

Questions before you buy

What comes in the pack? One CE400X black cartridge and three color cartridges: CE401A cyan, CE402A yellow, and CE403A magenta.

How many pages are the cartridges rated for? The listing gives up to 11,000 pages for black and up to 6,000 pages for each color cartridge at 5% coverage on Letter or A4 paper.

Will it fit every HP LaserJet printer? No. Compatibility is stated for a set of specific M551, M570, and M575 models. Check your exact model and cartridge code rather than relying on the HP name alone.

Should you buy it?

Choose this set when your printer is among the listed models, the cartridge codes check out, and replacing black, cyan, yellow, and magenta together suits your printing needs. The high stated yields may be useful for regular document and color printing, but the coverage condition matters, and the code mismatch in the listing makes careful model-and-cartridge matching part of the purchase. If you need just one color, or cannot confirm the A-suffix cartridges are right for your printer, a single correctly matched replacement is the more sensible route.
