coolscan V (LS50) scan problems

[cheezy]

Hi all,

 

Hopefully someone out there will be able to help me. I've googled the forum

and have taken some action all to no avail. Any advice has got to be better

than the Nikon "support".

 

I've just bought this scanner.As soon as I got it I tried to scan a B/W neg no

problem. Since then it will preview with the nicon scan 4.02 software, but

stops on the actual scan, locks up for 5 minutes then no image is saved, or

shown on the desktop in Nikon scan. Tried to aquire the image through the

coolscan using photoshop same problem. Started asking questions, took off the

nikonview software, removed the registries, eventually turned through this

site to Vuescan. At least in Vuescan you can "see" the scan. So same thing

preview not a problem. Main scan and it stops, randomly as little as 1% in as

much as 95% in. Freezes for 5 minutes, but it does then save what it has

scanned up until the freeze point.Thought it must be a hard ware problem spoke

with warehouse express who sent a new one and picked up the old next day (I

highley recommend them). Got it last night it scanned the first slide no

problem, but ever since only part scans in Vuescan.I haven't put the Nikon

scan software on.

I sent my entire system details to Nikon support, who can't see a problem with

them. I suspect its a buffer problem, if so any quick fixes? Otherwise it's

going back for good.

My system is Pent4 2GB processer, upgrades USB2 card, 1GB RAM plenty of HD

memory, recently upgraded Nvidia 6200 graphics card.

This problem still happens with all USB connections unplugged. I haven't tried

it on the old PC USB1.1's that are hard wired on the PC, I'll try that tonight.

I'm scanning in 8 bit B/W's with no fancy alterations so the file is "only"

20MB.

 

Please help ASAP , as I've got 6 days and counting to return it.

I think it is buffer or problem with your computer not being able to store the data fast enough.

 

Defrag the data base so storage is more efficient.

 

Try scanning to lower rez to see if smaller files help.

 

The less the corrections you try to make at the scanning stage, the faster it will run. ICE, color corrections, contrast changes all increase the time.

I will try this later tonight. Any other things to try welcomed. Other info I forgot to mention my O/S is XP (home) SP2

How can I adjust the computer data storage?

I would suspect a USB problem. The Nikon scanners appear to like to have a USB port to themselves. Do not connect it through a hub.

Thanks to Nigel and Ronald.

I did a de frag as soon as I got home. Then tried to scan a slide. It got to 96% in Vuescan, and was much quicker. But still no cigar.

 

To Nigel I was USB'd direct into the newish USB2/firewire card that I have installed, and I have tried previously taking all the other USB applications out and still no joy.However a colleague suggested also a buffer problem and said to try the old USB1.1 built in ports. At least this would slow down the scan and might allow the buffer time.

I tried this , and to my supprise not only has it scanned perfectly well all my negs and slides (so far)but it is still fast, even with colour correction 16 bit 4000dpi and sharpening plus infrared.I'm no computer expert, but I thought the old built in USB1.1 ports would remain USB1.1 even when I added an additional USB2/firewire card.

 

Thanks guy's for your help hopefully this might also help other people in the future.

 

Cheers
