Compatible HP CF287A 87A / Canon 041 Standard-Yield Black Toner | Up to 10,000 Pages | HP M506dn M506x Flow MFP M527c M527dn M527f M527z Pro M501dn Canon imageCLASS LBP312dn LBP312x MF521dw MF525dw | Premium Ink & Toner

The CF287A is the standard-yield version of the HP 87 black cartridge, rated for approximately 9,000 pages. The CF287X (87X) is the high-yield version, rated for approximately 18,000 pages — twice the output per cartridge. Both work in the same HP LaserJet Enterprise M506, Flow MFP M527, and LaserJet Pro M501 printer models. For high-volume enterprise environments, the CF287X delivers a significantly better cost-per-page.

CF287A and Canon Cartridge 041 are two part numbers for the same standard-yield black toner cartridge. HP designates it CF287A (also called HP 87A) and rates it at approximately 9,000 pages, while Canon designates it Cartridge 041 and rates it at approximately 10,000 pages — the difference reflects each manufacturer's own testing methodology. A single compatible cartridge works in both HP LaserJet Enterprise and Canon imageCLASS printers, regardless of which brand name appears on your supply order.

This cartridge is rated for approximately 9,000 pages (HP standard, ISO/IEC 19752) or up to 10,000 pages (Canon standard, ISO/IEC 19752) at 5% coverage. 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 reliable page counts across both HP and Canon printers.

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.
