What to check first
Step-by-step checks
- 1
Consumable check
Load the correct paper type in the indicated tray or change the driver setting to match the loaded media.
Start with the official recovery step before moving on to parts or deeper servicing.
- 2
Consumable check
Confirm the machine's Paper Type setting matches the actual stock in the tray.
- 3
Safe first step
Retry once the machine and print job agree on media type.
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.
Before the message
What users usually notice first
Messages like this often appear after the printer fails one of its normal startup, supply, or paper-path checks and cannot return to ready state cleanly.
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.
Avoid wrong turns
Common misreads of this message
- -Treating the message like a confirmed failed part instead of a support clue about which system has stopped the printer.
- -Assuming any supply-related wording means the next step is automatically to buy a cartridge, toner, drum, or printhead.
- -Assuming no physical path issue exists just because no full sheet is visible at first glance.
