This tutorial walks through the procedures for removing and loading the toner cartridge for a Brother printer.

Here's how to replace the spent cartridge.

1. Open the front of the printer.

2. Remove the drum & toner cassette.

Here you see the toner cartridge latched in the cassette that also holds the drum.

3. Push down the blue/teal lock lever and swing the used toner cartridge up and out.

Here's the toner cartridged removed from the cassette.

4. Unpack the new cartridge.

Hold the cartridge level with both hands and gently rock it from side to side five or six times to spread the toner evenly inside the cartridge.

Then, pull off the protective cover. Note: Save this and other protective materials for storing the used cartridge.

5. Install the new toner cartridge. (You'll reverse the motions you used to remove it.)

Hold the gray handle and tip the cartridge downward slightly to slip it forward into the cassette.

Then lower the handle to latch it firmly in place.

6. Clean the primary corona wire inside the drum unit by gently sliding the blue/teal tab from right to left and left to right several times.

Return the tab to the home position (V) before you put the drum unit back into the machine.

7. Slide the cassette back into the printer.

Make sure it fully latches in place.

Close the front cover of the machine.

If it won't close all the way, remove the cassette and reinsert it fully.

Or, you might need to press the lighted button on the front-left corner of the printer to get its attention.
