The ADF-600EL Auto Document Feeder (ADF) extends the power of your flatbed scanner by letting you scan pages of text continuously. It is compatible with all of Microtek's ScanMaker-series letter- or legal-size flatbed scanners, feeding up to 10 pages for multi-page optical character recognition (OCR) of text documents. This accessory works for both Windows and Macintosh models. The ADF is easy to use. Simply remove the cover of your scanner, attach the document feeder, and the ADF is ready to go. Once the ADF is in place, you can still scan books and oversized originals as you normally would. Just lift up the document feeder, and place the materials on the scanner surface. Combined with the capabilities of your OCR application, the ADF instantly changes your ScanMaker flatbed from a sophisticated graphics tool to a sophisticated document management tool.
