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.
Operator panel
A panel containing the scanner indicators and buttons. The operator panel is used to control scanner
operations such as loading document, selecting features, and changing setup options.
Outline extraction
The boundary between black and white areas is traced and the outline extracted for closed areas.
PAPER JAM
A warning informing the user that document is jammed in the transport unit, or that transportation is
disabled because the transport unit is slippery. This warning also appears when a Multi feed is de-tected.
Photograph mode (White level follower OFF)
Selecting photograph mode makes brightness and contrast settings effective but prevents the threshold
from being set. With photograph mode, the darkness of image corresponds to the black-pixel density,
making it suitable in scanning images such as photographs having gradations.
Photo mode = photograph mode
A photograph is read properly in this mode.
Pick start time
The period from the manual insertion of the document until picking starts after the document passes the
hopper empty sensor.
Portrait orientation
A document is transported and read with the long side parallel to the moving direction.
Paper counter
Indicates the total number of read document from start of reading until the hopper becomes empty.
Read operation
Refers to the reading operation including Simplex reading and Duplex reading.
RS-232C interface
A type of serial interface. See Serial interface.
SCSI-ID
Used to specify a particular SCSI device when the initiator selects a target or the target reconnects to the
initiator.
Serial interface
A standard computer interface. Information is transferred between devices over a single wire (although
other wires are used for control).
With a serial interface, an interface cable greater than 3 meters (10 feet) can be used. This is often
necessary in networking environments, where the scanner may be shared.
