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.
Temporary Error
An error correctable by the operator.
Time-out limit
This is the time the scanner waits for next document insertion after the last document
feeding. The scanner returns Paper Empty when no document is set after time-out limit.
