When the rear of the first sheet passes the first delivery roller, the stacker controller PCA stops the stack-delivery motor (M32) and then rotates it in reverse. The stack-delivery motor rotates the stack-delivery roller and return roller and delivers the paper to the processing output bin. The paper in the processing output bin is detected by the processing-output-bin paper sensor (PI38). When the paper is delivered to the processing output bin, the swing motor (M36) starts and raises the swing guide. When the swing-guide home-position sensor (PI35) detects the rising of the swing guide, the swing-guide motor stops and holds the swing guide at the raised position. After the processing-output-bin paper sensor detects the paper, the aligning motor (M33/M34) starts and aligns the paper. 596 Chapter 8 Output accessories and intermediate paper-transfer unit (IPTU) ENWW
