3.4.5 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 and the buffer path 2 sensor (UN13,UN14).
M4:buffer motor
SL1:buffer path switching solenoid
UN13:buffer path 1 sensor
The buffer operation takes place as follows when 3 sheets of paper are moved:
