Overview
M
Multi Image
A function which outputs the image in both color/grayscale and black & white at once.
Multifeed
Multifeed is an error when two or more sheets are fed through the ADF at once. It is also called a multifeed when a different
document length is detected.
Moiré patterns
Recurrent patterns on scanned images caused by incorrect settings of angles.
N
Noise removal
A function which improves the quality of an image by removing isolated noise that appear as black dots in a white area (or vice
versa).
O
OCR (Optical Character Recognition)
A device or a technology that recognizes the text on documents and converts them into text data that can be edited. The
shape of the characters are recognized by the differences in the light reflected off the documents.
Operating environment
Conditions (e.g. temperature, humidity) required to operate or store the scanner.
Operator panel
A panel that consists of a display and buttons. It is used for scanner operations such as selecting functions and changing
settings.
Optical sensor
A sensor which detects the changes in the amount of light transmission. Paper feeding errors such as multifeed and paper jam
are detected by monitoring the passing of documents.
