i have a problem with my xerox workcentre 4250
1) i can't set up the scan
2) i can't print using the reseau
any help please or any full tutorial
1, Why can't you and what scan? You need to provide vastly more information, the thing can scan to FTP/SMB/Email/Folder on the printer and USB drive.
2. Are you trying to say network? If so, why not just run the Web based print driver installer on the drivers page for this machine? If you are on the same network as the printer it will find it during the install wizard and grab and install the appropriate driver.
Nobody can provide you a tutorial, you supplied nothing to start with. If you have specific trouble in a specific issue on a specific operating system used in a specific way, you need to list them.
