No, you must change sides manually. Only the printing function switches sides automatically,

Single-sided scanning only, double-sided printing

Hello Susan,
Unfortunately, there is no duplex scan function. However, if you want to copy a document printed on both sides so that the copy is output as a double-sided document, there are corresponding settings for this. However, the document must be scanned on the original glass and turned over by hand; this setting does not work via the ADF. Here is a link to the online user manual with detailed instructions: https://support.brother.com/g...

Hello, no, it doesn't have duplexing. It has an automatic document feeder that can scan several pages at a time, but no duplex function.

I don't think this works with this device, I haven't found any reference to it in the manual or in the software.

Unfortunately it does NOT have a duplex scan!
