Compiler section paper feed
After receiving the paper from the feed section, the compiler feed roller pushes the paper between the raised upper
exit roller and lower exit roller. The paper falls due to its weight, and the trailing edge lands on the compiler assembly.
The paper toggles the sensor (staple finisher tamper paper present).
