Go to Flag 2 on BSD 10.5 (2 of 2) and troubleshoot the +5V circuit.
Go to Flag 1 on BSD 10.5 (2 of 2) and check the wire between P/J167 -2 on the Oil
Empty Sensor and P/J413A -3 on the IOT Drive PWB for an open circuit or a short
circuit to a voltage source. If the wire is OK, replace the Oil Empty Sensor ( PL 8.7 ). If
the problem continues, replace the IOT Drive PWB ( PL 9.2 ).
Reinstall the Sensor. Make Sure that the green circuit pwb faces AWAY from the Heat
Lamps. Close the Front Door. If the “Replace the Fuser Oil Cartridge soon” message
remains, check for a loose connection at
P/J167 or P/J413A . If the harness is good,
replace the Oil Empty Sensor ( PL 8.7 ).
Replace the IOT Drive PWB ( PL 9.2 ).
