The feed motor feeds the separated original to the skew correction roller [A] at maximum
speed. After skew correction, t he feed and transport motors f eed the original through the
scanning area at a lower speed (t he scanning area contains the original exposure guide [B]
and DF exposure glass [C]). After scanning, the or iginal is fed out by the transport roller [D]

Soon after the trailing edge of the original pa sses the exit sensor, the junction gate solenoid
switches off and the junction gate [E] is closed. When the original has been fed onto the

Basic Operation B790 4 SM 2.3 BASIC OPERATION At the appropriate time after the leading edge of the first sheet of copy paper reaches the copier’s registration roller, the junction gate solenoid turns on to switch the junction gate to direct the paper to the 1-bin paper tray. The junction gate solenoid turns off at the approp riate time after the paper is directed to the 1-bin paper tray. The main motor in the copier stops after the final sheet passes the 1- bin tray exit sensor and arrives on the tray. The paper sensor turns on when there is paper in the tray, and the paper indicator turns on. The tray can be opened for easier jam removal by swinging the tray to the left.
