Abstract
In a high speed printing station, cut sheets are separated one by one sequentially and transferred through the printing station. When a sheet jamming occurs in the feeding unit all sheet transport means are stopped, the previous sheets remaining and moving in the printing and ejecting units are wasted and components in the printing unit are contaminated by toner powder. The control method of the present invention comprises steps of (a) detecting the sheet jamming occurring in the feeding unit by a first sensor, (b) stopping the transporting means in the feeding unit only, (c) continuing operation of other transport means until the second sensor in the ejecting unit detects an ejection of all previous sheets in the printing and ejecting units, and (d) stopping the other transport means. The sheets except the jammed one become available for use and the contamination by toner powder is avoided.
