When you use the TN 730 and TN 760 cartridges that don't have a chip, you will need to remove the chip from the OEM cartridge and replace it into your new, no chip, cartridge. Because your OEM chip was already used previously, your printer will remember it. You need to set your printer to ignore the "Replace Toner" message.
