5. INLET CHUTE ASSEMBLY ANALYSIS
Is the resistor securely mounted to the bottom of the Inlet Chute Assembly?
Yes No
Go to Step 6 Replace the Inlet Chute Assembly.
6. WIRE ASSEMBLY ELIMINATOR ANALYSIS
Is there continuity (0
Ω) Ω)
between both ends of the Wire Assembly Eliminator (the green
wire with one end secured to the bottom of the Transportation Chute Assembly and the
other end at RTN on the HVPS)?
Yes No
Go to Step 7. Replace the Wire Assembly Eliminator.
7. WIRE ASSEMBLY FRONT ANALYSIS
Is there continuity (0
Ω) Ω)
between both ends of the Wire Assembly Front (the black shrink-
wrapped wire connected to the Front Plate Assembly)?
Yes No
Go to Step 8. Replace the Wire Assembly Front.
8. TEMPERATURE SENSOR ANALYSIS
Is there continuity (0
Ω) Ω)
between P/J101–4 and P/J101-1 on the Fuser Assembly?
Yes No
Go to Step 9. Replace the Temperature Sensor.
9. LVPS ANALYSIS
Is there continuity (0
Ω) Ω)
between P/J101–5 and Frame Ground?
Yes No
Go to Step 10. Replace the LVPS Assembly.
10. HVPS ANALYSIS
Disconnect all HVPS P/Js except P/J 111.
Use Diagnostic Tool tests DG91, DG92, DG93, DG94, and DG95 to check the HVPS outputs.
Is the noise still present?
Yes No
Go to Step 11. Replace the HVPS.
