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.
Multi Image
A function which outputs the image in both color/grayscale and black & white at once.
N
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 apart. 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)
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.
Operational environment
Conditions (e.g. temperature, humidity) required to operate or store the scanner correctly.
Operator panel
A panel that consists of LCD and buttons. It is used for scanner operations such as selecting functions and changing the
