I thought I could get a replacement cartridge from my copier manufacturer. Then two non-original devices were delivered in a box. One of these pads was well received, but after a month I'm already getting streaks of toner. I shake the device and everything is fine - but for how long? It looks like it's time for another replacement device soon. So it doesn't matter. I usually buy high-volume replacement toners made by my copier manufacturer. I get at least a year of service with light moderate use on a single cartridge. I'm a self-paying teacher, so I'll be more careful in the future.
