Go to step 2.Pull the TonerTape out, then goto step 2.2 Does the error still occur when the power is turned ON? Go to step 3. End of work3Checking after replacing the CARTRIDGE ASSY (M)Replace the CARTRIDGE ASSY (M).Does the error still occur when the power is turned ON?Go to step 4. End of work4Checking the Dispenser Motor for rotationDoes the Dispense Motor function normally?Checked by [Digital Output] - [DO-23(Control Panel)/TONER MOTOR M ON(PC)] in diagnosis. During the test,close the interlock switch (HARN ASSY INTERLOCK).Check the gear ofthe Auger is notdamaged. If thegear is damaged,replace the DIS-PENSER ASSY.(Refer to Removal24/Replacement20)Replace thePWBA MCU.(Refer to Removal30/Replacement14)Go to step 5.5Checking the connector for connectionCheck the connectors between the PWBA MCU and DIS-PENSER ASSY.Are P/J18 and P/J182 connected surely?Go to step 6.Reconnect theconnector(s)P/J18 and/orP/J182 surly,then go to step 6.6 Does the error still occur when the power is turned ON? Go to step 7. End of work7Checking the HARN ASSY LV TOP for continuityDisconnect P/J18 from the PWBA MCU.Disconnect P/J182 from the DISPENSER ASSY.Is each cable of P/J18 <=> P/J182 continuous?Go to step 8.Replace theHARN ASSY LVTOP.8Checking the power to DISPENSER ASSYDisconnect P/J18 on the PWBA MCU.Are the voltages across ground <= >J18-A7pin/A8pin onPWBA MCU, about +24 VDC when the interlock switch(HARN ASSY INTERLOCK) is pushed?Replace the DIS-PENSER ASSY.(Refer to Removal24/Replacement20)Replace thePWBA MCU.(Refer to Removal30/Replacement14)
