Whats the difference between toner and toner indo ? -

I think you mean toner and drum kit. The drum kit is a consumable part and will need to be replacing when your print appear excessively blackened, or you get a check drum warning. The drum kit clips onto the back of the toner. It usually for about three times as many pages as the toner. If you find you don’t have any ink, you need to change the toner. If you find your print appear excessively blackened, or you get a check drum warning, which means you need to change the drum kit.
