Card reader
4
You can use the machine’s USB port to connect a card reader to the machine. If the card reader is connected
to the machine, you can use card authentication to print storage data. Because the user’s identity is confirmed
simply by touching the card to the card reader, the user can access their storage data directly. In addition,
because others cannot access the storage data, card authentication is effective at preventing unauthorized
access to the personal storage data.
For details about the card reader and card authentication, please refer to the Card Reader Operation Guide
located on the Manuals page for your model on the Brother Solutions Center web site at
