Summary: We have three of these and all have more than a million scans on them. When things get dirty (optics/mirrors) you don't see it on the images but deskew and its ability to find the page can start getting crazy. Some types of paper are hard to separate and we will get lots of multifeeds.
Pros: It's built to scan big stacks (500+ sheets) of paper at 120 pages per minute (B/W 200 dpi duplex) all day long. It also does color and higher resolutions, but your speed will be slower. If you scan more than 500,000 pages per year and time is money, this will work for you.
Cons: Yes, some of the rollers are hard to get to. Also, the optics/mirrors need cleaned about every 1,000,000 pages. I'm doing this myself (takes about 2-4 hours) rather than pay $$$ for a service contract (be careful).
Summary: This is not a scanner I would purchase again, especially not at this price. Do not waste your time, otherwise it will waste yours.
Pros: The speed and quality of the images are great when the Beast is actually working, however is as fussy as a toddler and equally as particular: Everything must be just SO for it to actually work well. When it does work, it cranks out batches quite fast and with
Cons: We've had nothing but problem after problem with this scanner, especially connecting with Kofax & VRS and Symantec anti-virus. Between multi-page feeds, firmware failures, inconsistent communication with Kofax, and random corners of pages blacked out, it's been a technical nightmare. It's actuall...
Summary: I purchased one of these through an institutional grant, so I didn't care about cost. But I would never pay my own money for one, as this doesn't work that much better than my old scanner that was only $4,000 and its alot more "fussy".
Pros: Its quite fast and works very well with OCR software (like Teleform).
Cons: It will start double feeding unless you change the rollers on a nearly monthly basis. The roller kit costs hundreds of dollars and it pretty hard to install. Also, if it feeds dirty paper (I use it for scanning surveys), it is a pain to clean out.
