Skanner gir elendig resultat - defekt?

[Alastor]

Har planer om å scanne inn en del bilder, men det funker jo dårlig når resultatet blir slik som dette, har noen noe tips til hva det her er? Innstillinger er default, bruker HP's egen programvare. Scanneren det gjelder er en Scanjet 3970, den har stått ubrukt og avslått i ca 2 år, på samme sted i en PC-pult. Ikke koblet til strøm engang.

Horizontal lines are an event in time. Rainbow colored lines might be due to a flickering lamp. Or the scanner has an internal high frequency power supply for the lamp, and it might cause such a problem. A faulty or incorrect or insufficient power cube may be the problem. Is the problem everywhere, or random locations, or always in one place in the carriage travel? It could be irregular movement of the carriage due to loose belts or sticky guide rods or other mechanical interference can cause "glitches". You might notice the lamp flickering, or watching the carriage carefully while it moves might show some type of binding. Horizontal lines due to lamp problems are random, showing at whatever location of the carriage at that point in time, but a sticky carriage would probably always be seen at the same location. Effects of an insufficient power cube is probably seen all over the image.

Så, trøbbel med strømforsyningen? Kan bli kinkig å få testa ut sånt...
