Table 1-55 Motors used in stapling
Abbreviation Component name Function
M105 Stapler-shift motor Moves the stapler
M41 Staple motor Performs the stapling operation
The stacker controller PCA moves the stapler according to the specified stapling position. When the
rear of the first sheet passes the first delivery roller, the stacker controller PCA stops the stack-
delivery motor (M102) 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 (PI108). 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 (PI105) 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.
