If you aren't concerned about the paper originals getting wrecked you could use an automatic document feeder and scan up to like 50 at a time.
If you care more for quality then use the flatbed scanner on a printer or a dedicated document scanner. Some scanner apps on Linux let you scan multiple flatbed images, which is just a timer that waits a certain number of seconds before starting another scan. That should make things a little quicker, but most ways will have you spend hours to scan 1000 documents.
