After over 20 years of faithful service my Nikon Coolscan 4000 has gone to scanner heaven. It had malfunctioned in a way that I’d seen once before - it wouldn’t release the film strip module. I remembered taking the cover off and messing around and eventually got it give up the module - however not before I broke an essential part of the scanner!
I grieved for a minute or two and then decided I would eBay the accessories - while listing them I found someone with the exact scanner in almost new condition for a reasonable price. So I am now complete again. I did sell some of the accessories which helps defray the cost of the new (used) scanner.
