Hi Louis The necessary ports on the firewall are open, yet scanimage -L does not find the scanner. But this lead to another discovery: I enabled LAN on the MG7550. And although the unit is connected via USB 2 xsane sometimes works?! But with LAN disabled xsane never works without prior scanimage -T. And once xsane or scanimage -T failed all succeeding calls fail until the scanner is switched off and on again. Log of xsane working: [sanei_debug] Setting debug level of pixma to 21.
