Cool Toner P3015 CE255X 55X Black Toner Cartridge, 2-Pack

A two-pack of black CE255X 55X toner helps keep compatible laser printers supplied for everyday document printing. Each cartridge is designed for listed HP LaserJet models, including the P3015 and M521 series.

The stated page yield is 12,500 pages at 5% coverage on Letter/A4 paper. That gives you a clear reference when planning toner replacement for routine office or home-office printing.

Need a replacement for a listed printer and a spare ready for the next change? This compatible cartridge set provides two black toner cartridges in one purchase.

The essentials

This is a compatible black toner cartridge set, not an HP-branded cartridge. The two-pack is suited to keeping a replacement on hand while the first cartridge is in use. Its single-color laser toner format is intended for black-and-white documents such as forms, reports, correspondence, and other everyday paper output.

The listed compatible printers include HP LaserJet P3011, P3015, P3015d, P3015n, P3015dn, P3015x, and P3016 models, as well as the Pro 500 MFP M521dn and M521dw and Enterprise 500 MFP M525f, M525dn, and M525c. Match the printer’s model name to the compatibility list before installing a cartridge, this helps ensure you select the correct toner family for your machine.

The stated yield is 12,500 pages at 5% coverage on Letter/A4 paper. Actual page counts vary with how much of each page is printed, so text-heavy documents and graphics can use toner at different rates. The yield figure is a useful planning reference rather than a guaranteed count for every print job.

How to use it

Install the cartridge in a compatible printer according to the printer’s normal toner-replacement procedure. For a practical office setup, keep the second cartridge stored as your next replacement so printing can resume when the cartridge in use needs changing. This two-pack approach is particularly useful for teams or home offices that print documents regularly and prefer to have the next black toner ready.

Getting the most from it

Use the printer model list to check compatibility before opening the package, especially when several LaserJet models are used in the same workplace. The set is a compatible replacement option for shoppers who want black toner for a supported printer, while those choosing between purchasing one cartridge at a time and keeping a spare may value the convenience of having two available.

The 5% coverage yield provides a consistent basis for estimating toner use across ordinary document workflows. For example, an office printing letters and forms can use the listed figure to plan when to keep a replacement nearby, while recognizing that pages with more printed content may use toner differently. The cartridges are intended for paper printing on laser printers, making this set a focused choice for routine black output rather than a multi-color printing setup.

Final verdict

For owners of the listed P3011, P3015, P3016, M521, or M525 printers, this Cool Toner two-pack brings together black compatible toner, a stated 12,500-page yield at 5% coverage, and a spare cartridge for the next replacement. It suits document-focused printing where matching the correct printer model and having toner ready for ongoing use are the priorities.
