Abstract
A method of stopping a printing operation in a facsimile system includes detecting a ring signal, receiving image data to be printed in the printing operation after detecting the ring signal, and stopping the printing operation and displaying an error message when the image data is determined to contain a predetermined number of consecutive black data lines. The predetermined number of consecutive black data lines represent a length on a recording sheet that is greater than or equal to a selected millimeters.
