Remaining paper detection apparatus for sheet-fed rotary printing press

摘要

The apparatus includes a print switch, the remaining paper detection apparatus, and a controller and a remaining paper detection controller. The print switch sets a printing press to a printing operation mode. The remaining paper detection apparatus detects remaining paper sheets on a convey board. The controller and remaining paper detection controller inhibit the print switch from setting the printing operation mode when a remaining paper sheet is detected by the remaining paper detection apparatus.
