Refilling the Brother TN-1090 toner cartridge is a cost-effective way to maintain your Brother monochrome laser printer. This specific cartridge model belongs to a global series including TN-1000, TN-1030, TN-1050, TN-1060, TN-1070, and TN-1075. Consequently, this guide provides a universal procedure for disassembling and cleaning these units to ensure high-quality results.
Disassembly & Cleaning
- Side Cover Removal: First, unscrew the metal screws holding the gear-side end cap. This action allows you to access the internal mechanism safely.
- Gear Removal: Subsequently, remove the plastic gears with care. You must note their exact positions to ensure correct reassembly later.
- Developer Roller Extraction: Gently pull out the developer roller. This step reveals the toner hopper underneath.
- Cleaning: Clean the developer roller and the doctor blade thoroughly. Use a soft, lint-free cloth because debris can cause permanent streaks on your prints.
Refill & Reassembly
- Toner Loading: Carefully pour the dedicated Brother toner powder into the reservoir. You can use the filling opening or the roller gap for this task.
- Roller Installation: Re-insert the developer roller now. Furthermore, make sure the side bushings align perfectly with the cartridge frame.
- Gear Reset: Re-position all gears correctly. If you own a “starter” unit, you must set the reset gear to the “new” position to clear the toner error.
- Final Seal: Replace the side cover and tighten the screws. This final step secures the entire assembly for immediate use.

Professional Advice: Always apply a thin layer of starting powder (or toner) to the edge of the new cleaning blade before assembly. If the blade is installed “dry,” it may stick to the drum surface and flip or damage the new drum during the very first rotation.
