Right-click in the unloaded part and choose to refresh.
The issue is usually related to a delay in response caused by the Fiery being between you and the printer.
I assume you have already re-booted them though (Both, do not assume rebooting the copier actually rebooted the Fiery)
I have a problem with my Versant 80.
The "scan to PC function doesn't work". It's very strange because in the printer web interface I go to the "Properties/Network Scanning" and when I click to any option says:
Internal Server Error
An error has occurred at server when processing request.
So I can't configure and change any data for the scanning configuration
Thank you and sorry for my english
