V700 scanning problem w/ICE on MF negatives

[andrey_paramonov]

<p>Hello,<br /> <br /> I have a strange problem with my (recently purchased) Epson V700. I use Epson Scan v3.24. I'm scanning medium format film (tested only with color negs, 6x4.5) using regular film holder.<br /> <br /> The problem itself - a piece of scanned image looks scrambled starting at 1/6-1/5 of picture height from the top and affecting the whole width for approx 1/10 of the picture height when using ICE on lite settings (low <br /> level) with resolution equal or more then 2400dpi (see the picture links). 1200dpi with ICE is Ok and I didn't test resolutions in between 1200-2400dpi.<br /> <br /> Side note - scanning 35mm is not affected and also when using ICE on high result is Ok - although it takes approx 10 minutes per scan. Silverfast SE gives the same problem probably due to the usage of the same ICE processing modules.<br /> <br /> The same behaviour is reproduceable on both my home computers (newer one Amd x2 with XP 64 bit 2GB RAM and on old Dell m700 laptop with some celeron and 1GB of RAM). However, VueScan results are not affected (sic!) in general although some strange lines are visible - white line on top and black on the bottom (a few pixels height).<br /> <br /> Pictures:<br /> <br /> 1200dpi, no problem:<br /> /> <br /> 2400dpi, with problem:<br /> /> <br /> Again, this only affects scanning 6x45 negs with ICE on low with Epson scan program with dpi >= 2400<br /> <br /> Anybody seen that problem? Any suggestions? <br /> <br /> My thoughts:<br /> <br /> - if it were on every scan - I would probably blame hardware.<br /> - most likely some issues with memory buffers while processing MF scan.<br /> <br /> Thanks,<br /> Andrey</p>

<p>A.P., I remember vaguely having experienced similar issues trying to scan glossy paper prints. Turning off ICE, or reducing the level of the artifact neutralizing sw, took care of the problem. In general it seems that ICE on the Epson flatbed scanners have an issue with shiny (glossy) materials. Canon's flatbeds (limited dynamic range) with their FARE sw, seem to be doing better in that respect.</p>

<p>Hello Wolf,<br>

Thanks for the reply. Strange that the problem affects only medium format film. VueScan also works Ok (although doesn't have that conveniency of batch scanning from EpsomScan). Anyway, I'll see if it possible to get some response from Epson support.</p>
