True Color Toner CE400X High-Yield Black Two-Pack

This twin-pack supplies two high-yield black toner cartridges built to replace the HP 507X (CE400X) originals. It is intended for offices that run HP LaserJet Enterprise 500 colour M551 series or LaserJet Pro 500 colour MFP M570/M575 series machines and want a lower-cost supply without changing workflow.

SMTC and ISO quality-assurance testing on every

The manufacturer runs each unit through SMTC and ISO test protocols before it ships, so toner formulation, charge consistency and drum life are verified against a documented standard. That testing replaces the guesswork that often comes with unbranded refills and gives IT buyers a repeatable benchmark for print density and background cleanliness.

Cartridges seat directly in the standard HP toner

Each unit matches the OEM form factor, so installation is a simple slide-and-click with no adapters, firmware overrides or gear realignment. The two-pack layout lets you keep one cartridge on the shelf while the other runs, avoiding emergency orders during high-volume periods, though shops that need colour toner or a higher page count per cartridge will need separate SKUs.

Questions about this item

When will I need to replace the CE400X black toner cartridges in my LaserJet Enterprise M551?

Each CE400X high-yield black cartridge is rated for approximately 11000 pages at five percent coverage, so replacement timing depends on your actual print volume.

What limits continuous printing with the CE400X cartridges in an M575 MFP?

The cartridge page yield of 11000 pages at five percent coverage is the primary limit; once toner is depleted, print quality fades and the cartridge must be swapped.

How much heat or noise do the CE400X cartridges add during all-day printing on a LaserJet Pro M570DW?

The toner cartridges themselves generate no heat or noise; all sound and thermal output come from the printer engine during operation.
