I have a Cannon C3220 Image Runner
The device copies , scans, faxes, emails, and prints in color (32ppm).
It can scan a document and send it to a folder on your server or any other user drive/folder. I think the document feeder can hold about 50 pages at once. It can also process double sided scans no problem.
This is a good mid-scaled solution that really works. I am using the scan function to image my file room files onto electronic media.
This device is also capable of creating a PDF that is approximately 90% smaller than an average PDF created using the Acrobat Distiller. IF you have a lot of files to process, this will save a bundle on disk space/media storage.
good luck
