What to try
Check the condition this code actually names
Read the indicated cartridge part/order number and compare it with Brother’s supported toner for this color-laser platform, then install the correct supply in the correct color position.
Keep the test focused
Change only the setting, supply, paper path, or component named above. Leave unrelated network, driver, and service settings alone so the retest tells you something useful.
Run a controlled confirmation test
Let the machine recognize the replacement and print a simple test. Keep other toner cartridges unchanged while confirming the correction.
After each corrective action
Retry the original operation that produced Wrong Toner Cartridge. If it works, stop there rather than moving into unrelated troubleshooting.
If the code returns
If the message remains with the documented cartridge, record the full part number, color, and printer model before contacting support.
When service may be needed
Do not modify cartridge keys or identification contacts to make an incompatible toner fit. Use the correct supported supply.
Continue with guided troubleshooting
