The D8BE01000000.local name suggests that it is using mdns AKA bonjour.
nslookup does not do mdns so no surprise that it fails.
Try
$ avahi-resolve --name D8BE01000000.local
But it looks like scanimage manages to resolve the name anyway.

Hi Louis,
I tried nslookup, but the name is not known in the network. I even added
this name in /etc/hosts but with same result. I noticed that D8:BE:01
are the last 3 bytes of the MAC Address of the printer
(88:87:17:D8:BE:01), not sure if this is relevant.
The firewall is not up so neither the TCP nor the UDP port gets blocked.
I made a trace with SANE_DEBUG_BJNP=5 and you find the result below.

Balthasar
PS: I missed notification for this list, so it took a long time until I
recognized your last response. Sorry for that.
