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 cir-
cuits 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 cir-
cits.
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 standars of security,
usability and environmental matters. "
TWAIN (Technology Without Any Interesting Name)
A standard for API (Application Program Interface) or protocol for imaging devices (scan-
ners, digital cameras, etc.) developed by TWAIN Working Group. In order to use devices
that comply with this standard, it is necessary to install driver software based on the
same standard.
