Preparation for refilling the Brother MFC-L 2740 CW MFC-L 2740 DW TN-2310 toner cartridge:
Before you start filling, please read the instructions carefully. When filling toner cartridges, we generally recommend wearing gloves and a fine dust mask.
This Brother toner cartridge is very easy to fill. Place the toner cartridge on the table in front of you. Carefully remove the label (Figure 1). Below is the sealing plug. With a spatula or a small screwdriver, you can remove the sealing plug with small lever movements (Figure 2).
Before you fill your toner cartridge, you must remove the old toner powder. Due to different physical and chemical properties, the new and old toner can clump together. Vacuum or shake out the old toner powder into a tight plastic bag.
Take your refill toner bottle and screw a funnel on top. This funnel makes it easier for you to dose more precisely during filling. Fill the toner powder into the toner cartridge (Figure 3). When you have filled your toner cartridge, you can reinsert the sealing plug.
IMPORTANT: The cartridge must be absolutely closed. Check the cartridge for leaks by tapping gently on a piece of white paper. No toner should trickle out of the laser cartridge.

Before you fill your toner cartridge, you must remove the old toner that is still present. Shake it out in a tight plastic bag or vacuum it with a toner vacuum cleaner. Because of the frequent heating and cooling again, the used toner has different physical properties than new toner powder.
Safety note for handling refill toner: Refill toner and toner powder can be harmful to health if improperly handled. We expressly recommend the use of respiratory protection equipment or suction chambers when filling toner cartridges. In addition, toner powder and refill toner can be extremely flammable with an appropriate oxygen mixture. Also, be careful not to touch the photoconductor drum or expose it to direct sunlight. This can lead to incorrect printouts. Eurotone assumes no responsibility for the success or failure of the procedure described.
