Brother No Toner After TN760 Replacement
Fix common causes of a Brother No Toner message after installing a TN760 cartridge.
The short answer
If No Toner appears just after fitting TN760, check that the cartridge is the correct one and is locked into the drum carrier. The checklist here is for the US HL-L2390DW. Keep the drum counter unchanged: fitting toner is a different task.
For your printer
HL-L2390DW · US · OK and arrow buttons. Confirm whether you changed toner or the drum. If the panel or market differs, use that model’s manual.
Check or replace the toner cartridge

- Confirm a toner message, not a drum message. If toner is already new, verify packaging, SKU and seating before buying again.
- If recently printing, let hot internal areas cool before touching anything. Touch only the designated consumable handles and lever.
- Keep toner level over disposable paper; do not touch the photosensitive drum surface, use sprays, or open electrical housings.
- With the printer on and idle, open the front cover. Wait for hot parts to cool, then remove the toner-and-drum assembly.
- Lower the green lock lever to release the toner cartridge. Keep the drum.
- For a new cartridge, unpack it and remove the protective cover. Fit the correct toner into the drum until it locks.
- Slide the green corona-wire tab gently from side to side several times. Align its arrow with the home-position arrow afterward.
- Reinstall the assembly, close the cover and leave the printer on until it returns to Ready.
Check the result: Print a test page when Ready appears. A drum-counter reset is not a toner-recognition fix.
If it did not work: If a correctly fitted new cartridge is still not recognized, contact Brother or the cartridge supplier with the exact model and part label.

Before you start
- Read the full model and market label.
- Keep the new cartridge’s box and receipt while checking the installation.
The new cartridge is there, but the printer cannot use it
Start with the installation you just changed. Follow the model-specific checklist above to check the protective cover, toner-to-drum latch and complete assembly seating. Stop if the cartridge does not fit without force.
If No Toner remains with the correct new cartridge seated, contact Brother or the supplier with the model, TN760 label and exact message. Ask about an exchange or further checks before paying for another cartridge. A drum reset does not resolve toner recognition.
Worth avoiding
- Do not force the cartridge.
- Do not buy DR730 unless a drum message or drum defect appears.
