Printers are shipped with special starter cartridges that lack the flag gear mechanism required to reset the toner counter. Therefore, if you will be refilling starter cartridges, you will either need to purchase a set of flag gears (available only for some models) or reset the toner level using the printer's hidden resets menu. See: How to reset your Brother printer's page counter.
You will need one flag gear per starter cartridge. Flag gears are also sold individually.
This Flag Gear Kit contains the following:
