How many pages does the high-yield black cartridge for the Canon imageCLASS MF455dw deliver compared to the standard one?

The high-yield 069H black cartridge delivers 10,000 pages, while the standard 069 black cartridge gives you only 3,000 pages. That’s more than a 3:1 ratio for a modest price step-up, so unless your print volume is trivial, you’ll save money per page by going straight to the high-yield cartridge.
