Xerox DocuMate 3220 is a popular scanner for legal size sheets.

The reason we highly recommend this scanner is because it is a flatbed scanner with a an automatic document feeder (ADF) scanner as well.

So basically, you would be able to scan delicate and large documents using the flatbed and you can use the sheetfed ADF mechanism for scanning loose sheets of paper automatically.

The ADF has the speed to scan about 23 papers per minute (ppm) or 46 images per minute (ipm), which considered a fair speed for an ADF mechanism.

Another important feature to note here is that the ADF has the capacity to scan 50 pagess at a time. It also has the single pass duplex scanning feature so basically it can scan both sides of a document in a single go.

Both ADF as well as the Flatbed on this scanner have the capacity to scan legal size documents. The Maximum paper size for ADF is 8.75 inches x 38 inches. Whereas the Maximum paper size for Flatbed is 8.5 inches by 14 inches.

All in all, if you need a popular and a robust scanner, then we highly recommend this as one of the best legal size flatbed scanners.
