Can you scan documents to your iPhone without both devices being on the same WiFi network? I would need this on-the-go without relying on public WiFi networks.
Asked by: Adam
Yes the Brother DS940DW can send the files to your smartphone. If you encounter problems using he devices on different networks, the scans can be saved to a microSD card (sold separately). After the scan is saved to the card, you can transfer the files to your smart phone later when you are back at your home wi-fi network.
