Refill instructions for Brother TN-2320, TN-2310, HL-L 2300, 2320, 2340, 2360

Preparation for refilling Brother TN-2320, TN-2310, HL-L 2300:
Take a Phillips screwdriver and loosen the two marked screws (Figure 1), then remove the side cover. The drive gears and the reset lever are located underneath. To refill the toner cartridge, you must remove the reset lever and the spring, and then take out the sealing plug. Remove the spring (Figure 2). You can then remove the reset lever (Figure 3). You can now remove the colourless sealing plug (Figure 4).
Once you have removed the sealing plug, you will be able to see the filling opening (Figure 5).
Before refilling your toner cartridge, you must remove any remaining used toner. Shake it out into a sealed plastic bag or vacuum it out using a toner vacuum cleaner. Due to repeated heating and cooling, the used toner has different physical properties to new toner powder.

Refilling Brother TN-2320, TN-2310, HL-L 2300:
Take the bottle of refill toner and give it a gentle shake. Then screw the funnel onto it. Shaking the bottle and using the funnel will make it easier to measure out the correct amount whilst refilling.
Now carefully pour the new toner powder into the toner cartridge (Figure 6). Once you have refilled your toner cartridge, you can replace the cap that you removed earlier.
All you need to do now is set the reset lever to the correct position. In the next section, we’ll show you how to do this.

Fitting or resetting the reset lever on the Brother TN-2320, TN-2310 and HL-L 2300:
The locking plug you have just inserted also serves as the mount for the reset lever. Therefore, place the reset lever and its spring onto the locking plug (Figure 7). Make sure you position the reset lever and the left-hand gear as shown in Figures 7 and 8.
This means inserting the left-hand gear so that the small arm points to the right and the raised part of the reset lever points downwards to the right, as shown in Figure 8. The reset lever will then indicate ‘full’ again. Once the reset lever has been fitted, you can replace the side cover that you removed at the very beginning and secure it with the two screws. You can now reinsert your toner cartridge into the printer.
