Fujitsu FI-5530C2 Operator's Manual page 174

Separation roller
A roller that separates the sheets of paper from each other.
Simplex reading mode
A mode for scanning only the front side of the document.
Smoothing
A process that eliminates "jaggies" from slanted lines and curves. Irregular convexities
are deleted and irregular concavities filled in. This is useful in OCR applications, for
example.
Storage temperature/humidity
The temperature and humidity levels necessary for proper storage of the scanner.
Temporary Error
An error that can be fixed by the operator.
Terminator
Devices with a SCSI interface can be daisy-chained. A resistor that includes terminal
circuits needs to be placed at both ends of the SCSI chain when devices are daisy-
chained. If a device (such as a scanner) is the last device in a chain, leaving an interface
connector unused, a Terminator therefore must be attached to provide those terminal
circuits.
Third Party Interface
Used to install optional board provided by FUJITSU or interface board manufactured by
a third party.
Threshold
A value used as a metric for judging a color as black or white. For scanning an image
with gray gradation, this value must be defined. The threshold setting determines which
pixels are converted to black and which will become white.
TUV
"An institution that controls products for conformity with various standards of security,
usability and environmental matters. "
