The sensors associated with the feeding of booklets includethe feeding sensor (PS102) and the paper exiting sensor (PS108).1. OperationThe feeding operation consists of entrance feeding and exit feeding; these, however, differbetween trim mode (trimming performed) and through mode (trimming not performed).a. Entrance Feeding(1) Trim ModeThe feeding motor (M101) moves the booklet delivered by the saddle finisher to the en-trance feeding assembly at a speed of 500 mm/sec.The motor goes OFF a specific period of time after the feeding sensor (PS102) mountedthe pressing assembly detects the leading edge (folded side) of the booklet to stop mov-ing the booklet. At this time, the fold edge of the booklet is hit against the stopper of thepressing assembly and held in wait for cutting.(2) Through ModeThe feeding motor (M101) goes ON at the same timing as in trim mode. However, themotor shifts to delivery operation without going OFF, as the booklet need not bestopped once for trimming operation.5VBLKCONTCLKPLLF/R24V24VP.GP.G5VINGND5VINGND24VDRVM101_CONTM101_CLKM101_BLKM101_PLLM101_F/RPS102_SIGPS108_SIGM105_CONTM101Trimmer DC controller PCBTrimmerdriverPCBM105PS102PS108
