Nicolas First of all, thanks for your quick answer. Unfortunately SANE_DEBUG_PIXMA gave absolutely no about at all. I then started scaned from the console with option -d128.
This is the output I got: kangaroo:~# saned -d128 [saned] main: starting debug mode (level 128) [saned] saned (AF-indep+IPv6) from sane-backends 1.1.0-cvs starting up [saned] do_bindings: trying to get port for service "sane-port" (getaddrinfo) [saned] do_bindings: [0] socket () using IPv4 [saned] do_bindings: [0] setsockopt () [saned] do_bindings: [0] bind () to port 6566 [saned] do_bindings: [0] listen () [saned] do_bindings: [1] socket () using IPv6 [saned] do_bindings: [1] socket failed: Address family not supported by protocol [saned] run_standalone: waiting for control connection [saned] handle_connection: processing client connection [saned] check_host: access by remote host: 192.168.9.52 [saned] check_host: remote host is not IN_LOOPBACK nor IN6_LOOPBACK [saned] check_host: local hostname: kangaroo [saned] check_host: local hostname(s) (from DNS): kangaroo.pyramid.lan [saned] check_host: local hostname(s) (from DNS): (null) [saned] check_host: local hostname(s) (from DNS): (null) [saned] check_host: remote host doesn't have same addr as local [saned] check_host: opening config file: /etc/hosts.equiv [saned] check_host: can't open config file: /etc/hosts.equiv (No such file or directory) [saned] check_host: opening config file: saned.conf [saned] check_host: config file line: `#' [saned] check_host: config file line: `# saned.conf' [saned] check_host: config file line: `#' [saned] check_host: config file line: `# The contents of the saned.conf file is a list of host names, IP' [saned] check_host: config file line: `# addresses or IP subnets (CIDR notation) that are permitted to use local' [saned] check_host: config file line: `# SANE devices.
