[8] DISASSEMBLY AND ASSEMBLYThe disassembly and assembly procedures are described for thefollowing sections:1. High voltage section2. Operation panel section3. Optical section4. Fusing section5. Tray paper feed/transport section6. Manual paper feed section7. Rear frame section8. Power section9. SPF section (SPF model only)1. High voltage sectionA. ListB. Disassembly procedure1) Press the side cover open/close button and open the sidecover.2) Push up the lock pawls (2 positions) of the side cover, andremove the transfer charger.C. Assembly procedureFor assembly, reverse the disassembly procedure.D. Charger wire cleaning1) Remove the charger cleaner from the manual paper feed unit.Before disassembly, be sure to disconnect the power cordfor safety.1. Do not disconnect or connect the connector and theharness while the machine is powered. Especially becareful not to disconnect or connect the harnessbetween the MCU PWB and the LSU (MCU PWB: CN42)during the machine is powered. (If it is disconnected orconnected during the machine is powered, the IC insidethe LSU will be destroyed.)2. To disconnect the harness after turning on the power, besure to turn off the power and wait for at least 10 secbefore disconnection. (Note that a voltage still remainsimmediately after turning off the power.)No. Part name Ref.1 Transfer charger unit2 Charger wire1)2)2)1)1)TransferchargerLock pawl rearLock pawl front1)Y109500-5 Service Manual 8-1
