All that was needed for my Brother DCP-L2550DW was to 'apt purge' the manually installed drivers:
$ sudo apt --auto-remove purge brscan4 dcpl2550dwpdrv Then *BE SURE* to use the Brother installer script: linux-brprinter-installer-2.2.1-1.gz (or whatever your current version is from the support.brother.com website, etc.) Follow the instructions from the Brother download site and during the script installation to-the-letter(EXACTLY)! *** CAVEAT: use the printer I.P. addy if on a LAN and _NOT_ the auto- detected mDNS addy if you have an AT&T Fiber residential gateway such as mine(BGW210-700) which has a ".local" domain hard-coded in the DNS. This effectively kills mDNS(Avahi) broadcasts and so I'm not able to connect to the printer using that system.

But the scanner is no more recognized. Scanners that are affected are(besides others): - Epson Perfection V10 - Epson Perfection V1000 - Epson WorkForce GT-1500 - Brother MFC-8510DN - Epson Perfection V33 It is to note that the probability that the scanner manufacturers fix things others broke is below 100%.
