I ordered these toner as cheap replacement for my Canon i-SENSYS LBP 3010. It was more or less an experiment of mine, since I have seen in a different toner manufacturer that the same replica cartridges for HP CB435A and the Canon i-SENSYS LBP 3010 offers. What can I say, the toner also fits in my Canon printer and costs only a fraction of the original cartridge. They did very well!
