Four-Pack Compatible Toner for HP CF289A

This Laser Tek Services four-pack replaces the HP CF289A black toner cartridge. Each cartridge is an aftermarket unit built to match the original specification for HP LaserJet printers. The set contains four individual cartridges, each rated for 5000 pages. It is intended for offices or home users who print regularly and want a ready supply of black toner.

ISO-Certified Manufacturing and Yield Consistency

The cartridges are produced under ISO 9001 and ISO 14001 quality and environmental management systems. This manufacturing approach aims to deliver print quality comparable to OEM from the first page to the last. Consistent page yields help maintain steady output and predictable cost per page across all four units in the pack.

Suits M507 and MFP M528 Series Owners

Buyers with HP LaserJet M507 or MFP M528 series printers can use these cartridges directly. Shops needing colour output or users of other printer models should look elsewhere, as this pack only provides black toner for the specific compatible series listed.

Questions about this item

How many pages will each cartridge print before I need to replace it?

Each cartridge is rated for 5000 pages, so replacement timing depends entirely on your actual print volume.

What is the first limit I will hit during a long print run with these cartridges?

The page yield of 5000 pages per cartridge is the primary limit; the printer will stop when toner is depleted.

Will the printer run hotter or louder when using these cartridges all day?

These are standard toner cartridges and do not change the printer's heat, noise or power characteristics during extended use.
