I have owned a DR-2080C for about 6 months, and used it pretty hard.
Probably 80,000 pages so far. Generally very happy with the scanner.
It's nice that Canon sells a kit to replace the parts that wear out -
rollers and such - at a reasonable price.
The main suggestion I would pass along from my experience is that you
have to watch for gunk transferring from the originals to the scanning
elements. A very small speck of ink can cause a streak on thousands
of pages of scans before it's noticed. Annoying in many contexts and
fatal for OCR.
We plan to start scanning a blank page every thousand sheets, then
examining the pair of images (remember, it's a two-sided scanner -
only half the images are affected by any speck of goo) for problems.
We've also started packing a cleaning kit when we send the scanner
into the field.
Our experience has been one problem per 10,000 - 20,000 pages.
