Mirror Image - Fujitsu fi-4530C Operator's Manual

Interface
The connection that allows communication from one part of a system to another. For example,
electrical signals are transferred between the computer and scanner over an interface cable.
Inversion (Reverse-image reading)
In reverse-image reading, data is changed from black to white and vice versa.
IRAS
Initialization of the hardware.
Landscape orientation
A document is transported and read with the long side vertical to the moving direction.
Letter size
A standard paper size used in the U.S.A. and other countries. Paper size is 8-1/2 x 11 inches.
Linedrawing mode
Selecting linedrawing mode makes threshold and contrast settings effective but prevents brightness
from being set. The specified threshold value determines whether black or white pixels are
scanned. Line drawing mode is therefore appropriate for scanning text and line art images.
Manual Feed mode = Manual Mode
Requires the operator to feed each document manually into the ADF paper chute.
Manual start mode (<-> automatic start mode)
The reading operation is activated by pressing the START button in this mode. Available only
when video option board is installed.

Mirror image

The read image is symmetrically flipped to produce a mirror image of the original detected in the
main scanning direction.
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 scan-
ner 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 double feed is
detected.
