The message "Unable to -" ( "Unable to Change" "Unable to Clean" "Unable to Init" "Unable to Print" "Unable to Scan" ) is a general message and may appear for different reasons.
To clear the message, you need to disconnect the Brother machine from the power outlet to check the machine.

Check for foreign objects, such as a paper clip or scrap of paper, inside the machine.
Disconnect the machine from the power outlet and open the scanner cover by pulling up on the lower right corner of the cover. Look inside the machine and remove any foreign objects.
