Narrative:

Shortly after transitioning into darc from NAS my entire scope went blank. At the tie I had 4 IFR aircraft on frequency and had to revert to non radar. In addition to the 4 IFR aircraft, 2 VFR's were also under my control and had to be terminated. 10 mins passed (approximately) by prior to regaining darc. Prior to going darc we experienced problems in NAS with our adep printers. We went into darc anyway!
