This is a Lexmark OEM 10N0016 (#16) Black Ink Cartridge. Lexmark recently released a low capacity 10N0217 #17 Moderate Use Black ink cartridge. They contain half the ink as the 10N0016 (#16). We recommend only using the higher capacity 10N0026 cartridges and ink refill kits instead of the lower capacity 10N0217.
Page Yield (?)
Page Yield is an approximation of the number of standard pages that can be printed with one cartridge, usually measured at 5% page coverage. 5% coverage is a standard 8.5 x 11 inch page with a light letterhead, address and three paragraphs of text double spaced. If you print mixed text and graphics or WebPages your page coverage is closer to 15% and therefore the number of pages printed with each cartridge will be less. If you are printing photos your page coverage is close to 100% and the number of printed photos will be much less than the amount the number of pages you would be able to print if you were just printing standard text documents.
