HP CE390A 90A Black Toner Cartridge 10000 Pages

Genuine HP 90A Black Toner Cartridge

This genuine HP CE390A toner cartridge delivers consistent black output for HP LaserJet Enterprise 600 and M4555 series printers. It is supplied new in a single pack and designed for offices that need reliable, professional-quality documents without the risk of reprints.

Yield measured at five percent coverage

The quoted 10000 page yield follows the standard five percent coverage test, so actual output will fall when pages contain dense graphics or heavy text blocks. Operating limits sit between ten and thirty-two point five degrees Celsius with humidity from twenty to eighty percent RH.

Ten thousand pages of mono capacity

At the rated yield the cartridge handles high-volume mono workloads such as reports, invoices and forms across multiple users. It runs out when coverage consistently exceeds the test level or when print volume surpasses the ten thousand page rating.
