Summary: It's been nearly nine years, and my Epson 1640SU still works brilliantly. I bought this as a refurbished model from Epson, and it's amazing how it's managed to digitize my entire photo collection as well as that of much of my family. From Win95 to Windows 7, every time I bought a new PC, my faithful 1640SU came with me.
Summary: I am no techie by any stretch of the word, but anything that is quick simple easy and fast, I will take. My hubby purchased the scanner for us to scan our wedding pix and in no time I had scanned over 100 pictures. It is quick and quiet, I did not have to crop, lighten, clean up not one single picture. I have recommended this scanner to a lot of my friends.
Summary: Be aware buyers. Epson still doesn't have windows XP driver for this scanner. There is absolutely no reason the drivers are not ready as of Feb 2002. Even the ones coming out is not certified by Microsoft. I usually like Epson printers but this scanner is totally useless with my Windows XP system.
Summary: I hesitated a long time before buying this scanner, because it's very hard to know what quality, what definition one needs to get good prints from slides. This scanner is easy to install, easy to use. For slides, you must use the Twain 5 option in your Twain menu, but everything is very intuitive and you'll find the learning curve quite smooth. If you are looking to scan slides so that family memories, etc...
Summary: Scanning on the Epson 1640SU initially worked well. It was very fast, and the documents looked very good on my display. However, two of the main reasons that I wanted to use a scanner were making copies of documents and faxing documents. After I started using the Epson 1640SU scanner, I found out that I could not do either function, even though they say that they can.
Summary: Perfection 1640SU is my first scanner, so i can not compare it to anything, but it works very well for me.I think that it is very good product. However, my problem is - communication with Epson technnical support. There is no simple way to resolve simple question of scanner/printer compatability, other than long-to-wait pay-phone connection.
Summary: I purchased this scanner at the end of May...and have been using it since then with great results -- I scan photos mostly, but have also spent a lot of time recently with slides, many of which I took more than 25 years ago -- Just yesterday, I used the transparency adapter to work with a friend's slides from almost 40 years ago -- I used the 1200 dpi setting, then previewed, cropped, and scanned..
Summary: The Epson 1640u is a great upgrade scanner from a 600x1200 dpi scanner. With the recent drop in price it costs as much as my original 600x1200 scanner. The color and detail is very good. While the scanner is slow for high resolution scans using a USB connection (though a SCSI-2 connection is also available if you buy the cable and card), it still is quicker than the 600x1200 dpi scanner it replaced for more detailed scans.
Summary: I got this scanner to replace a UMAX 1220S that I had before. The UMAX had one big problem - I couldn't turn it off. It sat on my SCSI chain and if it saw any traffic it would stay on - since I have CD-ROMs on the same chain it was on constantly! After a while being constantly turned on must have hurt something because after a while I started getting chromatic distortion on sharp edges. So it became time to replace my scanner.
Summary: I found installation flawless, and operation reliable. I've had no problems with this machine at all. I'm running Windows 98 and I scan into Photoshop. When I "Import", Photoshop opens the Epson Twain software and I am able to scan without any problems. I can also The quality is quite good for the money I paid. I'm quite pleased with the product. The only thing I don't like is in the software. I cannot access my scanned image in Photoshop until I close Epson Twain.
