What are professional scanners like, what are they capable of doing?
They are able to create digital copies of paper sheets at high speed. They have high mechanical work load; although the manufacturers only suggest 3 to 10 thousand pages/ day, such devices are capable of scanning 3 to 4 times more. Currently almost each of them is a colour and double-sided (duplex) scanner. Their resolution may even be 600 dpi (dot per inch), however, for character recognition 200-300 dpi is enough. The size of the scannable pages ranges from the business card size to the A/3 size. Of course, an automatic document feeder (ADF) is required for high speed scanning, in case of a 20 to 40 pages/ minute scanner the capacity of the feeder is usually 50-500 sheets.
Please do not mix up such devices with the scanners sold in the department stores for 100-500 US dollars or Euro! The manufacturers of the state-of-the-art scanners are: Fujitsu, Kodak, Canon.
The professional document archiving scanners contain durable and strong metal structures, their purchase price ranges from 1,000 – 30,000 USD or EUR. In case of our automated data entry software solutions mainly the scanners for 2,800 – 6,000 Euro-s are the most popular ones.
