Film holders are not recognized - Nikon Coolscan 9000 ED
Nikon Coolscan 9000 ED I've been using for 6 years nearly every day now refuses to recognize the film holder._________It says, "No film holder detected. Try to clean the square holes at the front side of the film holder and if this doesn't work, try another holder." _____________ I tried all: cleaned all holders, opened the scanner and cleaned it from dust; restarted the computer; turned the scanner off/on/off/on with 5 min intervals. Nothing helped. ______ Then I tried another program - Viewscan. It also said, "Insert the film holder" while it was already inserted.______ Who knows what might it mean? That the scanner grew too old?
