Document ReversingBasic OperationThere are two types of document reversal operation: one that is performed from the top to the reverse side of the document andthe other that is performed from the reverse side to the top of the document.Since the basic operation methods are identical, only the reversal operation performed from the reverse side to the top is discussedbelow.■ Top side pickupThe Read motor (M2) drives the Lead roller 1 (upper) and the Platen roller to scan the surface of a document on stream reading.After completion of scanning, Read motor (M2) drives the Lead roller 2 (upper) and the Upper delivery reversal roller to feed adocument to the reverse point.Upper delivery reversal rollerPlaten roller Read roller 2(Upper)Read roller 1(Upper)M2 M2■ Reversal/Feed 1After the trailing edge of a fed document passes the Delivery reversal sensor (SR3), the Read motor (M2) stops.Thus a document stops at the reverse point. The Read motor (M2) drives in reverse direction to feed a document to the Registrationroller and then it stops. After that, the Release solenoid (SL1) turns on to release the Lower delivery reversal roller.Delivery reversal sensor(SR3)SL1M2SL1M2■ Reversal/Feed 2The Pickup motor (M1) drives the Lower registration roller through the Registration clutch (CL2) to feed a document to the Readwait point.Thus, the document is reversed. After a document is picked up again, turn OFF the Release solenoid (SL1) to pressurize at thesame time that reverse side reading is complete. After that, each operation is performed such as re-reverse, feeding anddelivering.2. Technical Explanation20
