If you are looking for a high quality flatbed scanner, or a scanner that can scan multiple page documents in a heartbeat then this is the scanner for you. The detailed manufacturer specifications are listed below but just to give you a general idea of the main features I will give you a brief synopsis: The scanner can scan multiple page documents very rapidly. Somewhere in the realm of 30 pages per minute. The resolution capabilities are OUTSTANDING!!! It can scan at up to nearly 1,000,000 dpi which gives you the capability of making huge enlargements if you choose too. These are the best features about this particular scanner. You will not find any of the new "all-in-one" scanners or other personal flat-bed scanners with the capabilities that this one has. This is a compact, professional grade scanner designed for industrial/business type usage. Needless to say it is extremely reliable. call/text (949)735-1385 with any questions or for a demo.
