Comments about Lexmark� C540A1YG *RP Laser Toner Cartridge; Yellow:
Although these cartridges are a tad expensive, they really put out the documents without having to replace that often. When we bought the printer that uses these it was a concern but I feel we really get our money's worth. There is a lot of toner in these guys.
Also, when your printer tells you to order a 'new' waste cartridge, just remove the old one, shake out what you can and replace it. It is literally a plastic box with a hole in it. No need to spend money on it.
Bottom Line Yes, I would recommend this to a friend
