Does the numberincrease one by one, as ACTUATOR NO PAPERoperates?Checks by Chapter 2 Diagnostic [Sensor/Switch Check].ReplaceHDVS/MCU.(RRP12.10)Go to step 5.4Checking SENSOR NO PAPER (2)Remove EP CARTRIDGE.Close COVER OPEN (PL1.1.2).Remove Paper Cassette.Put the hand from the tray insertion space, moveACTUATOR NO PAPER up and down. Is each voltageacross P/J24-8 <=> P/J24-7 and P/J24-3 <=> P/J24-2,0VDC when ACTUATOR NO PAPER is moved up, 3.3VDCwhen down?ReplaceHDVS/MCU.(RRP12.10)Go to step 5.5Checking the power to SENSOR NO PAPERRemove EP CARTRIDGE.Is each voltage across P/J24-6 <=> P/J24-7 and P/J24-1<=> P/J24-2 on HVPS/MCU, 3.3 VDC?Go to step 6. Go to step 8.
