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

CF287X and Canon Cartridge 041H are two part numbers for the same high-yield black toner cartridge. HP designates it CF287X (also called HP 87X) and rates it at approximately 18,000 pages, while Canon designates it Cartridge 041H and rates it at approximately 20,000 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 18,000 pages (HP standard, ISO/IEC 19752) or up to 20,000 pages (Canon standard, ISO/IEC 19752) at 5% coverage. Actual yield may vary based on document complexity, print settings, and average coverage per page. Enterprise environments printing standard business documents typically 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.
