Page Yield: Approx 190 Pages @ 5% Coverage
5% Coverage is a measure that printer manufacturers use to calculate the number of pages that can be printed with one cartridge This means only 5% of the whole page is covered with ink or toner. 5% coverage implies basic type with no bold characters, no graphics and no pictures.
Extended 2 Year Warranty
All of our ink and toner cartridges are backed by a manufacturer warranty period of 1 year. But at InkPost we think we can do better by extending the warranty on all ink & toner cartridges we sell to 2 years. CLICK HERE to learn more.
