How to Refill a TN-350
- 1). Position the TN-350 cartridge face-up with the refill plug facing you. The refill plug is a round cap on the side of the cartridge that is slightly larger than a quarter.
- 2). Insert the tip of the flathead screwdriver under the lip of the refill plug. Rotate the screwdriver to pry up the plug. Work the screwdriver around the plug until the plug falls out.
- 3). Pour any remaining toner out through the refill plug. Mixing old and new toner will degrade print quality.
- 4). Rotate the cartridge so the refill hole is facing up. Pour the new toner into the refill hole.
- 5). Position the cartridge face up. Replace the refill plug. Press on the plug until it snaps securely into place.
