Hello aizquierdo,
Scanning is not supported when using the imageCLASS MF4770n with Windows Server 2012 R2 (or any Windows Server operating system). If you want to continue to scan with your computer, you will need to use a Windows Vista, 7, 8/8.1 or 10 (or Mac OS X verison 10.5.8 and up) operating system; the MF Toolbox is available for these operating systems.
