Abstract
An automatically controlled plotter that generates graphic information on recording material in response to a plot program includes an optical sensor for detecting the traces or lines that are generated in the plot on the recording medium. The detected lines are compared with the programmed lines to establish if an omission or gap exists, and where there is a gap, the plotting process is interrupted or the program is repeated to retrace the defective portion of the plot, or the defect can be recorded for subsequent correction.
