Epson 4990 has inconsistant color from scan to scan

[cookseytalbott]

Hi All

I have had my Epson 4990 for a while and usually scanned one piece o
film at a time and reset the parameters for each scan.

All was well

I needed to scan 4 frames of 6x7cm VC-160 film and it exceeded th
scanners maximum area at 4800 DPI.

That was not a good sign..

The frames need to have the same color balance or it is a problem whe
I stitch them together

I started scanning the film 2 frames at a time and immediately notice
that the color was significantly (20-30 points) different from scan t
scan

Each scan takes 20+ minutes

I tried putting the scanner on a voltage regulator to eliminat
voltage fluctuations as the lamp is an analogue component. I als
upgraded the Epson scan software to the latest. I have not liked th
silverfast or vuescan results

I am still getting inconsistant color from scan to scan with the sam
settings..

I found an old post somewhere from Rafe where he had come to the sam
realization and had emperically proved the problem

Is there a way around this or is this scanner fatally flawed

In the Epson scanner driver, in "Professional" mode,
click on "Configuration." Then in the resulting
dialog, click the tab labeled "Other." Then click
"Reset All."

I can't say for sure that this is what did it --
but the scanner seems to be working much better now.

I'm using the Epson driver, in standalone mode.
