Four-pack black toner cartridges

This set contains four new black toner cartridges built to replace the HP 89A (CF289A) supply. Each unit includes a chip for printer recognition and is rated for approximately 20000 pages at standard yield. The pack is intended for offices that run HP LaserJet MFP M528dn, M528f, Flow M528c, M528z, M507x, M507n or M507dn devices and want a ready stock of replacements.

High-volume mono laser users

The cartridges suit environments that print large amounts of black-and-white documents and prefer to keep several spares on hand. They are not designed for colour output, photo work or printers that take a different cartridge series. Buyers who need colour toner or a single cartridge should look at other listings.

20000-page yield per cartridge

The approximate page yield of 20000 pages per cartridge is the key figure for planning consumable budgets and reorder timing. It reflects standard yield at typical coverage and determines how often the printer will request a new unit.

Questions about this item

Does the 4-pack include only the toner cartridges or are drums and other parts supplied as well?

The 4-pack contains four black toner cartridges with chips. Drums, fusers or maintenance kits are not included and must be purchased separately if required.

Should I choose the standard-yield 20000-page cartridges or look for a high-yield version?

These cartridges are standard yield at 20000 pages each. If your monthly volume regularly exceeds that figure, a high-yield alternative would reduce replacement frequency.

Will I actually get 20000 pages from each cartridge in my HP LaserJet M507dn?

The 20000-page figure follows the industry 5 % coverage test. Real-world yield varies with page coverage, duplex printing and environmental conditions such as the 10 °C to 30 °C operating range.
