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 a starter cartridge, you will either need to purchase a flag separately (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 available in a pack of 4.
Each Flag Gear Kit contains the following:
This flag gear kit is compatible with BROTHER HL-L8260CDW, HL-L8360CDW, HL-L8360CDWT, MFC-L8610CDW, MFC-L8690CDW, MFC-L8900CDW printers bought in NORTH AMERICA, LATIN AMERICA, and AUSTRALIA only. Customers from other regions, please contact us for more information.
