STROKE SPEED

In facsimile systems, the rate at which a fixed line perpendicular to the direction of scanning is crossed in one direction by a scanning or recording spot . ( 188 ) Note 1: Stroke speed is usually expressed as a number of strokes per minute. When the system scans in both directions, the stroke speed is twice this number. Note 2: In most conventional mechanical systems, the stroke speed is equivalent to drum speed .
