My solution:
I have the IP of the WF-2760 in the file /etc/sane.d/epson2.conf with root rights in the line net 192.168. *. registered and before the # removed.
ScanLite started and it worked.
XSane is however more comfortable and has a few adjustment possibilities more. Scan in *.pdf, ...
Maybe someone finds the XSane compiled for KaOS
