I bought this to archive paper (like bills). The auto document feeder scans 2 pages, then says: out of memory, close programs to free up disk space. I have a brand new computer w/ 512k memory and an Athalon XP 2500 processor. This error is clearly from the Scan Wizard software the scanner comes with. I have rebooted and reinstalled to no avail. All in all I spent about 3 hours trying to scan 20 pages. Now I'm going to return it and buy the HP model with auto document feeder for $299. I guess you get what you pay for at only $140 for the Microtek 5950.
