Our engineers carefully inspect each cartridge for flaws, refit it with a brand new drum unit and other internal components, then put it through a series of print tests. Each cartridge passes strict industry standard requirements, so you can be sure that every order you unbox from 1ink.com will contain a functional, high-performance toner cartridge. If you ever have any problems with your toner or you’re not completely satisfied, simply send it back – we offer a comprehensive one-year satisfaction guarantee on every purchase from 1ink.com.
