6.3.14 Pickup Solenoid failure
NOTES:
1. Without the diagnostic tool, skip the Diagnostic tool (DG) portion of step 3.
2. The control panel message may be: Paper Jam>Fuser
3. This FIP may also fix a bad sensor or toner cartridge.
4. Try to replace the pick-up solenoid before the MCU.
1. INITIAL ANALYSIS
1.
Inspect the following components. Are they compatible with your printer
version, correctly installed, not damaged, deformed, or contaminated?
• MCU PWB
• LVPS Assembly
• Pick–Up Solenoid
Yes No
Go to Step 2. Replace the problem components.
2. 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 17–1 and P/J 11–2 on the MCU PWB?
Yes No
Go to Step 3. Go to Section 6.3.2 LVPS Assembly Failure (+24VDC ).
3. PICK–UP SOLENOID ACTUATOR SIGNAL 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.
Use Diagnostic Tool test DG80 to check the Pick–Up Solenoid.
Is there 0VDC between P/J 17–2 and P/J 11–2 on the MCU PWB when you actuate the
solenoid?
Is there +24VDC between P/J 17–2 and P/J 11–2 on the MCU PWB when you do not actu-
ate the solenoid?
Yes No
Replace the Pick–Up Solenoid. Go to Step 4.
4. PICK–UP 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 17–2 and P/J 11–2 on the MCU PWB?
Yes No
Replace the MCU PWB. Replace the Pick–Up Solenoid.
