For a while now I have been a Brother evangelist because they just worked, they did not lock you into first party only printing supplies, and they were overall a good value.
THEN: my printer firmware auto updated and suddenly my toner cartridges were no longer recognized. Its not that they ran out and I put in new ones, simply the ones that had previously worked (3rd party already) just stopped and it reported an error.
I managed to find a guide on downgrading the firmware, and now I am back up and running and auto update is turned off. I am also saving all the little chips from the Brother branded cartridges.
So Dear Brother Printers, Please choke on a bag of dicks. I spent $500ish on a laser color printer so I would not have to deal with the shitification that has happened to inkjet. Seeing hostile and profiteering consumer behavior from other printer companies you decided to copy them for short term gains.
Well I will no longer recommend your products, and I will go out of my way to fix and downgrade your older printers with the sole purposes of putting them back into use and costing you new sales.
1 down, 1 in the cue, feel free to stop being anti consumer and breaking hardware we already paid for.

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.
