    Chapter 10 10.2.3 Paper Pickup Operation 0013-1195  The pickup unit consists of pickup and transport rollers. When the Start Key signal or Original Feed signal is input, the ADF motor (M2001) turns in the normal direction and then the pickup solenoid (SL2001) turns on. The pickup unit lowers and the pickup and transport rollers rotate to feed the paper.

    Chapter 10  10.2.4 Reversal Operation 0013-1196  There are two types of reversal operations, reversal from the top side to the reverse side and reversal from the reverse side to the top side. However, since their operating principles are the same, only reversal from the top side to the reverse side is described below.

  • Page 71: Delivery Operation

    Chapter 10 c. Reversal/Feed 2 The original is fed by the ADF motor (M2001), passing through the original scanning unit. Thus, the original has been reversed. After completion of re-pickup, the roller release solenoid (M2003) turns off at completion of scanning of the reverse side of the original.
