Chapter 38F-3-23.2 Variable Resistors (VR), Light-Emitting Diodes (LED), and Check Pins by PCB3.2.1 Light-Emitting Diodes and Check Pins by PCB 0010-1711Of the light-emitting diodes (LED) and check pins used in the machine, those needed in the field when servicing the machine are discussed herein.Do not use the variable resistors (VR) and check pins that are not discussed herein. A check using these will require the use of special tools/instruments and ahigh level of accuracy.3.2.2 Finisher Controller PCB 0010-1712F-3-3SW1: Use it for mode settingSW2: Use it for adjustment and test start-upLED1:Use it for checking the operationT-3-3Connector TargetJ1 power supply -J2 communication -J903PI1 stack edging HP sensorPI2 handing tray paper sensorPI3 paper surface sensorJ904 PI15 inlet sensorPI16 offset HP sensorJ905PI7 tray clock sensorPI8 stack tray paper sensorPI9 tray 300 sensorPI10 tray lower limit sensorJ906 M1 stack tray shift motorJ907 M2 feed motorM1[1]SL1M5M4M3M2SL2SW1511421421SW1SW2ON1 2 3 426125124312J916 J909 J908J917 J911J9041J910 J907 J913 J9201413J912J901J914 J903J902 J919151319126521313J905J915 J9062 121114 212 115 1J91817LED1
