Summary: I have a huge collection of transparencies and negatives that are in all formats; 35mm to 8x10 as well as prints. The ScanMaker i800 does a very good job handling most of the sizes. For 35mm I would use a separate scanner just for that size. The i800 is unusually slow although the new Microtek Scan Potter software improves the speed somewhat. The quality of the scans is very good and with some tweaking in Photoshop can produce more than acceptable files for publication.
Summary: I have owned this scanner for 5 years. Started off with WinXP. When upgrading to Win7 x64, it wouldn't work. Contacted tech support who said it could not run with Win7 x64. Made it work with Win7 x64 by manually inputting the registry entries. Has worked flawlessly for the last 3 years. The glass does appear to have some inside smudges, but since I scan mostly documents it hasn't been noticeable.
Summary: I have had the i800 for three years and on many occassions it has stopped working and caused all my USB ports to freeze. I have installed it on a Dell, a compaq, an Asus, an MSI, and an EVGA motherboard. If I have the scanner plugged in then none of my USB ports work. If I uninstall the scanner software then they all magicaly come back to life. Contacted tech support in 2009, 2010 and 2012. Most recently they continue to say this is the first they have ever heard of it.
Summary: I've owned this scanner for 3-4 years. The calibrating on startup is annoying, but I've learned to live with it. Had trouble installing it on a Win 7 x64 system, but finally got it working and since then it has worked flawlessly. The workaround was to manually export the original Registry settings to the Win 7 Registry. Maybe I'm the only one that had a problem installing. Scanner is slow compared to newer models, but the scan features are great.
Summary: This is one of the most disappointing pieces of junk I've bought in a while. We bought this scanner for its negative/slide/photo scanning capabilities. It did all of those things well until the warranty ran out. Then without warning it just stopped functioning. I can turn it on and it sits and makes a high-pitched squealing noise and that's about it. It did great quality scans, but for the price I'd expect a bit more life out of it.
Summary: For the past 8 years I used (pretty much daily) and LOVED my ScanMaker 3800. So my expectations were high. Boy was I ever disappointed? The drivers refuse to stay operable, so I have had to uninstall and reinstall them over a dozen times? Both the COPY and DIGITAL ICE quick buttons on front refuse to work? After spending 2 hours (the privilege I had to pay $12 for!!) with tech support they tell me it won't work because of my 3-in-1 HP printer?
Summary: I purchased the Microtek ScanMaker i800 flatbed scanner over a year ago and am well pleased with it. The main reason for purchase was that this scanner would scan negative and positive films up to 8 by 12 in in size, which it does very well. It does have a fairly high learning curve due of all the features/settings available for each scan. The only minor negative item is the fact that it is quite slow, as it has to calibrate itself for each scan.
Summary: I work for a museum that has a number of different negative formats in the collection. It is very hard to find transparency scanners that are able to scan sizes other than 35mm, let alone any size. I have been using this scanner for 3 years and have found it to do a great job with only a few temperamental moments. It is true that if users are planning to produce large files with the scanner, the better the computer the faster the scanner works.
Summary: The absolute worst online purchase I have ever made. The software included was not the software advertised or included with the manual, and after a month of contacting their support team (e-mail only, no phone number to talk to a real person) I returned the product. I was unable to make the first scan with their software. Needless to say I wasted many man hours and will never purchase another Microtek product in the future.
