[B] [D] [A] [C] [F] [G] [E] The original feed rollers rotate with the rotation of the main motor. The original is pulled by the 1st original feed roller [A] just after the original is placed on the original feed table. The original registration sensor [C] detects the leading edge of the original, and the "Set Original" indicator turns off. At the appropriate time, the copy paper starts to be fed again. The original passes between the platen plate [D] and exposure glass [E] and from there to the 2nd original feed roller [F]. The original's image is reflected through the fiber optics array [G] to the drum as the original passes between the platen plate and exposure glass. Then, the original exits the machine. At the appropriate time after either the original or copy paper exits, the image creation process (drum process) stops. When both the original and copy paper have exited the machine, the mechanical drive (main motor) stops. SM 2-8 A163
