EPSON WF-C5790/WF-C5790a/WF-C5710/ET-8700/WF-C5210/WF-C5290/WF-C5290a Revision A Configuration and operating principles Operating principles 51 Confidential Front Feeding Mechanism The front feeding mechanism is composed of the Pick-up mechanism and the intermediate feeding mechanism. Pick-up mechanism This mechanism picks up paper from the Cassette Assy and feeds it up to the intermediate feeding mechanism. The retard separation method is used for paper separation. The ASF Motor drives the pick-up mechanism. The pickup roller and separation roller uses a oneway clutch to always rotate in a set direction (paper feed direction) only. When the ASF Motor rotates the opposite direction of paper feeding, the drive force is cut off by the One Way Clutch, so neither the Pick-up Roller nor Separation Roller rotates. Figure 3-30.
