Abstract
A control system and method of operation for controlling the operation of a finished plot handling and rolling mechanism of a plotter. If the finished plot is not properly gripped for rolling, the rolling process is aborted and the plot ejected unrolled. During rolling, power to the driving mechanism is maintained at a level which will keep the media taut and prevent over powering. At the plot end, the media is made taut over the platen for consistent cutting. The trailing end is then accelerated at a level which will overcome static friction of the previously rolled portion and prevent buckling of the trailing portion.
