I am connected to my Brother scanner and PC via a USB cable, but I cannot scan or turn the scanner on.

Check the following:

Turn the machine off, and then turn it on again.
Disconnect the USB cable from the machine, and then reconnect it.
Use the USB cable that is included with the machine.
Make sure to use a computer that has a USB Type-C port that supports 15 W output or higher.
Try a different USB Type-C port and make sure it is capable of supplying 15 W output or higher.
Purchase the optional AC Adapter.
