Background
What this message usually means
Brother uses Media Type Mismatch or Media Mismatch when the printer driver and the machine menu disagree on the paper type for the selected tray. This is a settings conflict rather than a hardware fault, and it is common in office environments where trays are repurposed for different stocks.
Diagnosis
Likely causes
The printer driver is set to a different media type than the machine menu.
The tray was reloaded with a different stock without updating settings.
A networked print job sent a paper type the machine was not expecting.
Service
When service or replacement is more likely
- -This is a settings conflict first, not a feed or toner fault.
