Glossary M Mirror image The read image is symmetrically flipped to produce a mirror image of the original detected in the main scanning direction. Moire Patterns Recurrent patterns on scanned images caused by incorrect settings of angles. Multifeed detection A scanner function which detects accidental feeding of multiple sheets into the ADF. This can be set as both enabled/disabled. N TOP Contents Index Introduction Scanner Overview Loading Documents How to Use ScandAll PRO Noise removal Isolated noise from an image appearing as black spots in white areas and voids in black areas is removed to improve image quality. Common noise includes toner and fax particles. Noise reduction works via an algorithm that removes pixels up to 5 x 5 dots appart. A dot is 1/400 inch. A particle can be distinguished from a character as it is not connected to another dot within 5 pixels. O OCR (optical character recognition) Devices or technologies for identifying characters on documents and converting them into text data that can be manipulated. The documents are checked by light and the differences of light reflection are recognized as character shapes. Scan Parameters Various Documents Daily Care Consumables Operating temperature/humidity The temperature and humidity levels needed to assure the proper operation of the scanner. Operator Panel A panel consists of indicators and buttons. The operator panel is used to control scanner operations such as, selecting features, and changing settings.
