Compatible HP CF289A 89A Standard-Yield Black Toner Cartridge | 5,000 Pages | Fits HP LaserJet Enterprise M507dn M507n M507x MFP M528dn M528f Flow MFP M528c M528z | Premium Ink & Toner

The CF289A is the standard-yield version of the HP 89 black cartridge, rated for approximately 5,000 pages. The CF289X (89X) is the high-yield version, rated for approximately 10,000 pages — twice the output per cartridge. Both work in the same HP LaserJet Enterprise M507 and MFP M528 printer models. If you print frequently or in higher volumes, the CF289X delivers a significantly better cost-per-page.

All four are HP LaserJet Enterprise MFP M528 series printers and use the same CF289A toner cartridge. The M528dn is the base duplex network model; the M528f adds fax; the M528c is the Flow edition with advanced document capture; and the M528z is the top-tier Flow model with additional finishing options. All use the same CF289A / 89A toner.

This cartridge is rated for approximately 5,000 pages at 5% coverage per ISO/IEC 19752 — the industry standard for monochrome laser toner. Actual yield may vary based on document complexity, print settings, and average coverage per page. Standard business documents with typical text density generally achieve yields close to or exceeding the rated amount.

Yes. Every Premium Ink & Toner cartridge undergoes pre-shipment testing for toner density, chip compatibility, and print quality to ensure output meets or exceeds OEM standards — deep black text, sharp graphics, and consistent page counts from first page to last.

No. Under US federal law (Magnuson-Moss Warranty Act), manufacturers cannot void your warranty simply because you use a compatible aftermarket cartridge. You are free to choose third-party toner without risking your printer coverage.
