Go to step 2.Reseat theFUSER ASSY,then go to step2.2 Does the error still occur when the power is turned ON? Go to step 3. End of work *13Checking the connectors for connectionRemove the FUSER ASSY.Check the connections between the PWBA MCU andFUSER ASSY.Warning: Start the operation after the FUSER ASSYhas cooled down.Are P/J17, P/J171 connected surely?Go to step 4.Reconnect theconnector(s)P/J17 and/orP/J171 surely,then go to step 4.4Checking the HARN ASSY FUSER for continuityRemove the FUSER ASSY.Warning: Start the operation after the FUSER ASSYhas cooled down.Disconnect P/J17 from the PWBA MCU.Disconnect P/J171 from the FUSER ASSY.Is each cable of P/J17 <=> P/J171 continuous?Go to step 5.Replace theHARN ASSYFUSER.5Checking after replacing the FUSER ASSYReplace the FUSER ASSY. (Refer to Removal 8/ Replace-ment 36.)Warning: Start the operation after the FUSER ASSYhas cooled down.Does the error still occur when the power is turned ON?Replace thePWBA MCU.(Refer to Removal30/ Replacement14.)End of work
