I do have a licence for Vuescan so I downloaded the latest version of that and tried it, sadly same result. Vuescan (and Nikonscan) can see there's a scanner attached but reports it not working. Having read Barry's comment I have watched the green light when I switch it on. Initially it flashes steadily then a distinct set of rapid flashes before settling to solid green. I think the obvious conclusion has to be drawn. I have contacted the seller and he is adamant that the unit works and that somehow I've configured the software wrong. He is coming to see me in a couple of days and says he'll get it working. He seems to be a reasonable eBay trader so if, as I expect, he can't fix it then he will be resigned to a refund.

If it's possible to see the scanning head once film adaptors have been removed on this model it's worth checking what it does during initialization while the power LED is blinking. It should move to one end to locate it's home sensor (not sure which end, older models moved the towards the rear) then may move all or part way towards the front. In the older models I own when the grease hardened the head wouldn't get driven back to the rear of the unit so would creep to the front on successive scans then stay there and fail with the error even after power cycling - though not sure if your scanner is old enough to suffer from this yet. Any clicking noises or grinding when first powered on are also an indication of the mechanism not being driven properly (a whirring noise is normal motor movement though). I've not used USB models of nikon though (mine are older SCSI connection) so it's possible the scanner may interact with the PC on these and computer problems cause scanner errors?
From: Barry Watzman on 10 Jan 2010 21:43 I believe that the 8000 is scsi, but I'm not sure. The self test can be performed "stand alone" no matter what.

Just by way of a postscipt to my story with the Coolscan 8000 I bought via eBay, and by the way the unit I had was firewire connected. The seller visited me thinking this was nothing more than a software glitch. After an hour tinkering on his MacBook, two of my Macs and my Vista machine we came to agreement - the unit was faulty, he promptly refunded my money and took the scanner away with him. Subsequently a couple of things have happened. I got a reply from a Nikon repair shop who said the worst case scenario was that the main logic board needed to be replaced - £400 plus £100 labour plus cost / time to transport the unit to their premises. Add VAT and that would be over half what I had originally paid for the scanner. The vendor has contacted me and independently he has had the unit checked, the repair is less expensive and will come with a three month warranty so if he puts it on the market again he can do so with confidence. I am left with the relief of a close shave, and wondering if scanners such as this are worth buying without any form of warranty given the potentially high repair bills.

I think it was also available in SCSI, but also in FireWire. The ones I've ever seen have been Firewire but an SCSI version is possible I guess. |
