Unable to connect to scanner (simple-scan & Brother DCP-L2530DW)

Question

I'm using simple-scan with a Brother DCP-L2530DW printer/scanner. The printer works fine, but I'm having issues using the scanner.

I've installed the drivers:

jam@jam-ncase:~$ sudo dpkg -l | grep Brother
[sudo] password for jamie: 
ii  brscan-skey                                0.2.4-1                                amd64        Brother Linux scanner S-KEY tool
ii  brscan4                                    0.4.8-1                                amd64        Brother Scanner Driver
ii  dcpl2530dwpdrv:i386                        4.0.0-1                                i386         Brother DCP-L2530DW printer driver (lpd/cups)
ii  printer-driver-brlaser                     5-1                                    amd64        printer driver for (some) Brother laser printers
ii  printer-driver-ptouch                      1.4.2-3                                amd64        printer driver Brother P-touch label printers

When I start simple-scan, it says Ready to Scan - Brother DCP-L2530DW.

But when I click scan, the scanning animation starts, but then an error message pops up saying: Failed to scan, unable to connect to scanner.

I've googled the problem, and the things I've tried are:

• add my user to lp

• Running this command: sudo cp /usr/lib64/sane/libsane-brother* /usr/lib/x86_64-linux-gnu/sane

This did the trick on Ubuntu 20.04 for a brother MFC-L2710DW

sudo apt purge ippusbxd
