4. FEED SOLENOID ANALYSIS
Disconnect P/J111 from the HVPS. Perform this test within 30 seconds after switching power on.
After 30 seconds, the LVPS shuts down with a no-load condition.
Switch ON Main Power.
Is there +24VDC between P/J 13–11 and P/J 11–2 on the MCU PWB (Tray 1)?
Is there +24VDC between P/J 13–12 and P/J 11–2 on the MCU PWB (Tray 2)?
Yes No
Replace the MCU PWB. Go to Step 5.
5. TRAY 1 SENSOR HARNESS ASSEMBLY ANALYSIS
Disconnect P/J13 on the MCU PWB and P/J115 on the Paper Feed PWB.
Is there continuity (0
Ω)Ω)
between all wires on J13 and J115?
Yes No
Go to Step 6. Replace the Tray 1 Harness Assembly.
6. Have you isolated the problem to the Feed Solenoid 1 of Feeder Assembly 1?
Yes No
Go to Step 7. Go to Step 8.
7. FEEDER PWB ANALYSIS
Disconnect P/J115 and P/J201 on the Paper Feeder PWB.
Is there continuity (0
Ω) Ω)
between all pins on J115 and J201 on the Feeder PWB?
Yes No
Replace the Feeder Solenoid 1 of Feeder Assembly 1. Replace the Feeder PWB.
8. FEEDER PWB ANALYSIS
Disconnect P/J 116 on the Paper Feeder PWB.
Is there continuity (0
Ω) Ω)
between all pins on J115 and J116 on the Feeder PWB?
Yes No
Go to Step 9. Replace the Feeder PWB.
