Does your printer do nothing when you press the scan button? Does it give an error?
If it does nothing, try the following:
1) Click the Start button, and then click Run.
The Run window appears.
2) Type services.msc, and then click OK.
3) Locate dlci_device in the list of services, right-click the service, and then left-click Start.
4) Locate Print Spooler in the list of services, right-click the service, and then left-click Start.
If that doesn't help, let us know.
