I spent a bunch of money a few years ago to get the laser(ish) print+scan+telegram+allthethings Brother MFC-L3750CDW. Imagine my rage when I found that this thing has a document feeder but no way to scan both sides of a document stack. Not even with a manual step in their software such as flipping the stack over and running the back sides through. Infuriating and I didn't realize it until about a year later when I suddenly had to scan a ton of stuff. If someone knows of a good workaround, I'd love to hear it.
Many PDF software (the stock scanning app on my Linux distribution, PDF24 and PDFSam for example) can let you merge two documents with alternating pages.
So I scan the stack, flip it over and scan it again. The flipped over ones are mixed in but I have to select reverse order to what was scanned. It works best on small stacks of 10 to 30 pages, you have to double check the page count for them to be the same. If the scanner mistakenly skips scanning one a good chunk of the doc ends up out of order.
In Linux I'm pretty sure you can do that directly with the scanning tool.
How is it brothers fault that you bought something without checking if it has the features you need?
Yeah I mean who doesn't read up to page 630 of the manual and then interpret the lack of automatic 2-sided scanning to mean it won't even do manual 2-sided scanning, despite nearly every scanner on the market supporting that.

My L3770CDW can. Maybe that's the difference between the two, we could never figure it out when we bought it.
It is. There's a feature table in the manual and it's one of the glaring differences between the two. I never even thought to look into the details that closely, and even if it doesn't have the hardware to flip the paper around and scan the back, it should be a simple software feature to add.
For some big stacks I've just got the pair doc_front.pdf and doc_back.pdf and I was thinking about making my own stupid script to interleave the two docs into one.
