The stacker controller PCA starts the swing motor (M106) and lowers the swing guide when the rear
of the second paper passes the first delivery roller. The stack-delivery motor is reversed. The stack-
delivery motor rotates the stack-delivery roller (upper) and return roller and sends the paper to the
processing output bin. At this point, the stack-delivery roller (lower) does not rotate because the
stack-ejection lower-roller clutch (CL32) is disengaged. The output-bin paper sensor (PI38) detects
the processing-output-bin paper sensor (P138). When the paper is delivered to the processing output
bin, the swing motor (M106) 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 (M103/M104) starts and aligns the paper.

When the last sheet is aligned, the stacker controller PCA moves the aligning plate to the alignment
position with the aligning motor (M103/M104) (the paper is held by the aligning plate). Then the
stacker controller PCA staples at the specified staple position. After stapling, the stacker controller
PCA starts the swing motor (M106) and lowers the swing guide. Then the stack is ejected by the
stack-delivery roller, return roller, and stack trailing-edge assist guide.
