SD705 does not operate when the second and subsequent sheets of the second set are processed. (3) Third and subsequent sets: PS704 (FNS entrance) detects the rear end of the last sheet of the second set. Then, after a predefined time, SD705 (by-pass gate) is activated to pull the first sheet of the third set toward the by-pass. SD705 stops it operation when a predefined time has elapsed since PS704 (FNS entrance) detected the rear end of the first sheet of the third set. SD705 does not operate when the second and subsequent sheets of the third and subsequent sets are processed. 2.

The FNS CB (FNS control board) controls M702. The related signals are PS704 (FNS entrance) and PS718 (shift HP). 1. Operation In the sort or group mode, PS704 (FNS entrance) detects the rear end of the paper. After a predefined time period, M702 (shift) operates. Its rotation triggers the shift (travel) of the shift moving section. The shift roller, rotated by M701 (FNS conveyance), carries the paper while the shift operation is being performed. The completion of the shift operation is detected by the change of PS718 (shift HP) signal, from OFF to ON, and then M702 is deactivated. After a predefined time period has elapsed since M702 was deactivated, it is activated again. M702 stops when PS718 (shift HP) signal changes from ON to OFF. This operation allows the shift moving section to return to its original position to wait for the next paper to be shifted. This sequence of actions is repeated for each sheet to achieve offsetting of paper. 2-8 FN-112/FN-6/FN-121/FN-10 2.
