Chapter 66-36.1.5 PCBs6.1.5.1 PCBs 0008-1748F-6-5T-6-56.1.6 Variable Resistors(VR), LED, and Check Pins by PCB6.1.6.1 Variable Resistors (VR), Test Pins, Jumpers, and Switches 0008-1749This section lists only the variable resistors (VR), LEDs, test pins, jumpers, and switches required for after-sales service in the field.All other VRs, test pins, etc. are for the factory use only. The adjustment and check using these test pins, etc. require special tools, measuring instruments, and highprecision. Do not touch them in the field.1) ITB home position detection PCBF-6-6T-6-6[1] Waste toner detection PCB [10] Relay PCB[2] Registration detection PCB [11] Paper feeder Driver PCB[3] Density detection PCB [12] SCNT PCB[4] ITB home position detection PCB [13] Operation Panel PCB[5] Developing rotary/toner level detection PCB [14] Capacitor Board[6] High-voltage power supply PCB [15] NCU Board[7] Sub high-voltage power supply PCB [16] Modular Board[8] Print Power supply PCB [17] Scaner Power supply PCB[9] DC controller PCBSW No. FunctionSW201 Test print switch[1][3][2][4][5][6][8][9][10][12][14] [13] [15] [16][17][7][11]SW7151J71
