Hi, I bought one of the OKI B840 toners (20k) from you in early Feb this year. My printer’s telling me there are 10 left and the toner count is at 9786 which included the first initial toner that came with the printer! We’re a newspaper and print proof pages of adverts on A4 but also print our pages on A3, twice a month. There’s no way this toner would achieve 20k except by printing 1 text line out per page. My last HP A3 printer would last us over 4 months. Steve.
