EPSON 4870... 46mins to scan 8 slides

Had the res set at 3200, and the 8 (35mm) slides took 46 mins, with
lengthy warming up periods between each (and during each scan).

From what I understand, this is abnormally long... so what am I doing wrong.
Unit is only 24 hours old.

Is the ICE option checked? This adds quite a bit of time to the scanning
process. Your description of it needing to warm up between each scan sounds
like the ICE may be enabled.

Yes, ICE is checked. Ok, no slides on the rocks in future.

My last scanner was Umax 1200s, so can see a few improvements (Umax's
professional software was less tedious). Wonders why Epson does not make
the 35mm slide carrier able to independently hold the slides. You could
lift all 8 on/off scanner glass with the holder. As pointed out by others,
the hinges are inferior for such a heavy lid, and the shudder/click it
makes is particularly annoying.

Having said all that, am happy with the beast. Although, it is being
replaced after 24 hours due to dried moisture streaks/condensation on
underside of glass (in fact it's filthy).

I think you are doing fairly well if you are saying that total time
for 8 slides at 3200dpi took 46 minutes. Thats about 5 minutes 45
seconds each and you've got DI on. My old dedicated slide scanner at
2800dpi with DI on takes about 2 minutes each but without the ability
to batch scan. In other words I can't walk away from my computer if I
wanted to race you.

Realize that also you've got a multi use scanner. One that does
prints and film. There is a price to pay.

You have set the scanner to an odd multiple of the scan resolution.
Since the native resolution is 4800 dpi the scanner software has to do
a resample before the image is saved.
In addition ICE is very slow.
If you have many slides you might want to consider Vuescan. It will use
the IR cleaning function with it's own algorithm which is much faster
than ICE.
You can download and try for free, it's shareware.

I have several discussions of scanners and optimizing scans on my web
site. Just follow the tips link on the home page.

46 minutes for 8 high-res ICE captures sounds normal. With all the
"warming lamp" messages, scans often take 50%-100% longer than ES's
"time remaining" estimate.

If you don't like the normal operating sounds, make sure you don't
block the hinge-side calibration area of the document table. It'll
sound like a mini-jackhammer is rumbling away inside. :)

What in particular is wrong with the hinges? I'm not blown away by
the design, but I don't have any trouble keeping the lid balanced 90
degrees from the scanning table when I'm switching materials.

Down the road, we're both apparently due for some permanent
under-glass fog regardless of initial conditions. A pity.

What's up with flatbed design, anyway? Why is the hardest-to-clean
surface sitting wide open where *everything* that gravity pulls down
will land on it? Why have *glass* as the point of contact, so that
every new scan presents an opportunity for fingerprints or even
scratches? Why not have the neutral "reflective" backing as the
document-holding surface, and keep the glass and lens hidden away up
above until they're needed? Is it too hard to keep the mechanisms
stable? If the lens mechanism was top-mounted, wouldn't it even be
easier to remove and clean the glass without causing dust to rain down
into the works?

Well, why not? :)
