Unfortunately you made only the first step and not all.
Looking at
https://openprinting.org/driver/hplip/
will lead you via "Supported Devices"-link to
https://developers.hp.com/hp-linux-imaging-and-printing/supported_devices/index
At HP's website you'll search and find the information that it is Full supported.
HP LaserJet 400 MFP m425dn
Min HPLIP Version: 3.12.6
Chrome OS Support: Yes
Driver Plug-in: Yes
Supported Level: Full
Print Model: Mono
Scan PC: Yes
So, install the required hplip packages for Debian (OpenSource) and see that it is supported.
Thank you, Klaus! I was disappointed I didn't find it because I remember having to modify some CUPS driver or interface many years ago when I first got the printer. And that was to print. I'm not sure I ever got reliable scanning on Linux.
I'll report back soon.
