I was in a bind and couldn't find any HP206 OEM toners in stock so I turned to Revain. You need to transfer the chip from your brand HP toner cartridge to these aftermarkets. And color matters! I tried taking the black chip and sticking it on the yellow cartridge but the printer rejected it in the yellow slot so I took the OEM yellow chip and took this chip to test my yellow one. Fortunately, moving the chip is very easy considering the tools and instructions that came with the toner. If you're okay with a few minutes of work changing cartridges, it doesn't matter. After moving the chip, the printer prints but does not show the correct ink level. My biggest problem is that the color is off. So if you are printing photos or images that require accurate color representation, this toner may not be for you.
