Buffer Operation

The finisher controller PCB keeps a sheet of paper in the paper path and forwards it together
with the subsequent sheet of paper using the buffer motor (M4) and the buffer path switching
solenoid (SL1) with the help of the buffer path 1 sensor PCB and the buffer path 2 sensor
PCB (UN13, UN14).
