You do not need the whole of HPLIP. Even if you do install it, it
will not help - you will end up tying youself in knots with printing
(which is working) and scanning. All you require is libsane-hpaio
installed with the command given earlier.

Having said that, you have, very unfortunately, encountered LP Bug
#1797501:

https://bugs.launchpad.net/hplip/+bug/1797501

This is the reason for the lack of scanner discovery with scanimage.
It is revealed by your useful avahi-browse output for _uscan._tcp. The
error should show up in journalctl. The TXT record for _uscan._tcp has

ty=DeskJet 3630 series

The first three characters are removed to give

kJet 3630 series  (Check journalctl for this after doing scanimage -L).

and /usr/share/hplip/data/models/model.dat is searched for this device.
It does not exist, which is why you cannot scan. So - we will make it
exist!

Edit models.dat and add this section:

[kjet_3630_series]
scan-type=7

simple-scan should now work.
