Abstract
In a process for controlling on-line a parameter of a moving sheet, scan data from a cross direction scanning sensor (for example, for moisture) is retrieved from a memory while the sensor reverses direction at a turnaround point. This is accomplished by utilizing the direct memory access (DMA) capability of the existing computer system and plugging into the existing address, data and DMA bus of that system a printed circuit board which halts normal computer operation for minimum periods so as not to interfere with its operation.
