Abstract

A control device for a stencil duplicating machine having a stencil or master making section, printing section, paper feeding section and discharging section in an integrated assembly. Whether or not a master sheet is wrapped around a drum included in the printing section is determined to execute adequate processes stably at all times. During a master making process, whether or not a used master sheet is on the drum is detected. If one is present, a discharge command is issued. If one is not present a master is made and placed on the drum. During a printing process, whether or not a new master sheet is on the drum is detected. If one is present, printing is executed. If one is not present, printing is inhibited.
