The paper size sensor board [A] monitors the paper width.
The rear side fence is connected to the terminal plate. The pattern for each paper
width is unique. Therefore, the copier determines which paper has been placed in
the by-pass tray by the signal output from the board. However, the copier does not
determine the paper length from the by-pass tray hardware.
