Go to step 2. End of work.2Checking after reseating the FUSER ASSYReseat the FUSER ASSY.Warning: Start the operation after the FUSER ASSY hascooled down.Does the error still occur when the power is turned OFF andON?Go to step 3. End of work.3Checking the connectors for connectionRemove the FUSER ASSY.Warning: Start the operation after the FUSER ASSY hascooled down.Check the connections between the PWBA MCU (P/J17)and FUSER ASSY (P/J171).Check the connections between the FUSER ASSY (P/J171)and PWBA LVPS (P/J47).Check the connections between the PWBA LVPS (P/J501and P/J502) and PWBA MCU (P/J14 and P/J15).Are these connectors connected correctly? Go to step 5."Reconnect theconnector(s) P/J17, P/J47, P/J171, P/J501, P/J502, P/J14 and/or P/J15 correctly,then go to step 4."4 Does the error still occur when the power is turned OFF andON? Go to step 5. End of work.5Checking the HARN ASSY FUSER for continuityDisconnect J17 from the PWBA MCU.Disconnect J47 from the PWBA LVPS.Is each cable of J17 and J47 <=> P171 continuous?NOTE: P171 is attached to the frame.Go to step 6.Replace theHARN ASSYFUSER.6Checking the HARN ASSY LVPS for continuityDisconnect J14 from the PWBA MCU.Disconnect J501 from the PWBA LVPS.Is each cable of J14 <=> J501 continuous?Go to step 7.Replace theHARN ASSYLVPS.
