Hi Pat, thanks for your message. Any of the 4 toners on the following page are correct. Please note, that the compatibles are out of stock, and each cartridge prints a different number of pages but either one is correct. Ignore the last 2 products on the page as they are maintenance items (drum units), and you won't need those.
