GREENCYCLE 90A Black Toner Cartridge 6 Pack 10000 Pages

Six-pack compatible toner for high-volume offices

This six-pack of GREENCYCLE 90A black toner cartridges replaces the HP CE390A original and fits LaserJet 600 M601 M602 M603 and M4555 series printers. Each cartridge is new and ready to install, so IT teams can keep a spare supply on the shelf without waiting for reorders. The pack suits departments that print thousands of pages every month and want a single SKU to manage. Buyers who need colour output or a different cartridge model should look elsewhere.

10000-page yield at five-percent coverage

The headline specification is the approximate yield of 10000 pages per cartridge measured at 0.05 coverage on Letter paper. That figure decides whether the cost per page fits the budget and whether the replacement interval matches the maintenance window. If the office routinely prints dense graphics or full-page solids the actual page count will be lower and a higher-capacity option would be required.

Consistent density over long print runs

The smart chip and multi-layer sealed packaging keep toner flow stable from the first page to the last, preventing the density drop-off that can appear late in a high-yield cartridge. Shaking the cartridge horizontally before installation distributes the powder evenly, and the industrial-grade OPC and roller maintain sharp text through extended jobs. Offices that run continuous batches overnight will see the same crisp output at the end of the run as at the start.
