Important Update : We are unable to refill the Introductory Cartridge on Introductory or Starter Cartridge on the Brother HL 3040 Printer bec it has no FLAG GEAR. We can refill the HL 3040 toner cartridge if a FLAG GEAR is present, that means you have to buy a New HL 3040 toner cartridge and that toner cartridge can be refilled many times bec there will be a FLAG GEAR present which we can have it resetted everytime we refill it
This applicable for all new Brother Laser Printers
