Here is what you wrote and I followed your instructions at the end


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.

=====

It then began to work.
