good document scanner
A common complaint is this is not a duplex scanner. Actually, for a $200 scanner, duplex scans are quick and easy, but the documentation does not tell you how to do them. Here's the trick. When you click "scan" the "file save settings" dialog box pops up. Make sure "show addpage dialog" is checked.
ADF scanner with flatbed option for things that won't go through an ADF; For most documents, I use "office mode," PDF output with high compression, 300dpi (200 is only slightly faster, slightly smaller file size, but noticeably worse image quality), skew correction on (config>other).
I have absolutely no complaints about the scanner, but the documentation is terrible (hence 4 not 5 eggs); The on-line help has no index or TOC, although it does have a search function.
