1 - 59Chapter 1 TroubleshootingFIP2.5 SENSOR REGI (PL5.1.30)Step Check Yes NoPossible causative parts:SENSOR REGI (PL5.1.30)ACTUATOR B (PL5.1.17)150 FEEDER ASSY (PL5.1.1)HARNESS ASSY TRAY1 (PL5.1.37)HARNESS ASSY CHUTE (PL12.1.17)HVPS/MCU (PL12.1.19)LVPS (PL12.1.5)1Checking ACTUATOR B for operation and shapeRemove 150 FEEDER ASSY. (RRP5.1)Does ACTUATOR B operate smoothly? Is the flag ofACTUATOR B formed normally to shield the Sensordetecting point?Check if the flag of ACTUATOR B is formed normallyagain, pushing ACTUATOR B by inserting a miniscrewdriver from the paper entrance spacew at the lowerand side sections each of 150 FEEDER ASSY.With toolGo to step 2.Without toolGo to step 3.ReplaceACTUATOR B.2Checking SENSOR REGI (1)Connect the connector J241 of HARNESS ASSY TRAY1to SENSOR REGI, with 150 FEEDER ASSY removed.Remove EP CARTRIDGE.Close COVER OPEN (PL1.1.2).Does the number of Sensor/Switch Check increase byone, by moving ACTUATOR B with a mini screwdriver?Checks by Chapter 2 Diagnostic [Sensor/Switch Check].ReplaceHVPS/MCU.(RRP12.19)Go to step 4.3Check SENSOR REGI (2)Connect the connector J241 of HARNESS ASSY TRAY1to SENSOR REGI, with 150 FEEDER ASSY removed.Remove EP CARTRIDGE.Close COVER OPEN (PL1.1.2).Is the voltage across P/J24-11 <=> P/J24-10, 3.3 VDCwhen ACTUATOR B is pushed, and 0 VDC whenreleased?Measure the voltage by moving ACTUATOR B with a miniscrewdriver.ReplaceHVPS/MCU.(RRP12.19)Go to step 4.4Checking the power to SENSOR REGIRemove EP CARTRIDGE.Is the voltage across P/J24-9 <=> P/J24-10 on HVPS/MCU, about 3.3 VDC?Go to step 5. Go to step 7.5Checking HARNESS ASSY CHUTE for continuityDisconnect P/J24 from HVPS/MCU.Disconnect P/J245.Are the following continuous normally?J24-9 <=> J245-10J24-10 <=> J245-9J24-11 <=> J245-8Go to step 6.ReplaceHARNESS ASSYCHUTE.
