Your yellow channel is running thin — documents are looking washed out and the printer's telling you to swap it. This is the genuine OKI yellow toner that fits your MC770 or MC780. Pull the old cartridge, drop this one in, and the colour's back. No waiting on a national chain's 6-day delivery or a marketplace seller who 'will look into it.'
