Is the scanner on the same network segment as your computer? BJNP
detects scanners on the same network segment only (it has to use
broadcasts). If it is and your scanner is not detected, there is most
likely a firewall blocking some of the packets. Check the system log to
seewhich ones. After 1.0.23 I have rewritten the bjnp code to be more
consistent in which ports it uses.

But see comments above.

This is not expected. Saned is normally NOT required for the scanning
over the network to work, but this may be a configuration issue. I only
use scand in combination with scanbd, the scanner button deamon that
requiresd scand for its operation.

I cannot comment on this as my scanner does not have a page feed. Does
multipage scanning work over USB? If so, I would like t see some
logfiles. I can give you the details on the required settings when you
can confirm that it works right over USB

Well, it is always usefull to see if BJNP works with new scanners too. I
have only a single scanner available and appreciate any feedback I can
