I do use ICE with my 4870 when doing overnight batch scans where quick scanning is of no consequence. I have used it on occasional single scans and noticed the "warming up" message. A lot of devices and software seem to generate cryptic messages occasionally, that make little sense except to the engineers who embedded them. A music production program suddenly popped up one of these and I did a screen shot of it. "Access violation at address 00403360 in module 'bbw.exe'. Read of address 2020201C at 00403360 ." I e-mailed it to the publisher and got a very nice e-mail of thanks in return. In a couple of days there was a patch and I never saw the message again. I have no idea what it meant, but his development team did.
I think it is probably there so you don't make a mistake thinking the scan has been completed, and remove the film. I just scanned a negative, once with ICE and once without. Even though I had just done a scan, the warming up message was there as soon as I hit the [Scan] button. Without ICE it "warmed up" for 24 seconds then completed the scan.
With ICE the initial warm-up was 56 seconds. After a bit more than a minute of scanning, it did another "warm up" which took just over a minute. The completed scan with ICE took 06:34 while the non-ice ICE took 01:37. Of course time will vary depending upon the resolution.
Programmers think in ways that mere mortals do not, and they may enjoy being obtuse for its own sake. I expect the programmer thought that there would be no point in giving a verbose description of what was really going on, since users are too dumb to understand anyway. ICE requires an infrared scan for dust and scratches, plus a scan for content. Somewhere along the line, the dust and scratches are subtracted from the content. I expect it does the first pass - either for scratches or content - then stores it. This is when it says it is "warming up" in mid-scan. It does the second scan, then spends the rest of the six and a half minutes reloading the information, processing the subtraction, applying the settings and saving the image.
Instead of saying "loading the DigitalICE module", "Initializing the DigitalICE module", "Scaling the DigitalICE feature to the resolution set in the interface", it says "Scanner is warming up".
Instead of saying "Doing the infrared scan for DigitalICE", it says "Scanning". Instead of saying "Processing infrared scan", "Storing infrared scan", "Loading content scanning module", "Initializing content scanning module", "Scaling the content scanning to the resolution set in the interface", "Aligning content scan to infrared scan", it says "Scanner is warming up". When it resumes it says "Scanning".
Certainly, it could describe making the content scan, retrieving the infrared scan, doing the subtraction, doing the dynamic range, colour balance, and any other histogram functions, unsharp mask, grain reduction, colour restoration, etc. as each individual step is accomplished, but all that takes processing time and really is not of any importance to the user, since it is all handled by the scanner and computer without any user input.
The "Warming up" message may well be too cryptic, but the above is far too verbose. In the end the scan is made regardless of the messages, and that is the only thing that counts.
As per wear and tear on the machine, Epson estimates 100,000 scans between failures. As a matter of comparison, the V500 shows 36,000 and the V300 only 10,000 average cycles. Regardless of warm-up cycles, I doubt that many people will ever wear one out to the point that it can no longer be refurbished. At 10,000 scans per year, that is ten years before maintenance. Few users will even hit the 100k mark - that is a LOT of scanning. I expect that 100k may be a very conservative estimate, and the scanner may well be capable of a lot more scans than that.
Enjoy the scanner and don't worry.
