6.3.16 Turn Solenoid failure
NOTES:
1. Without the diagnostic tool, skip the Diagnostic Tool test (DG) portion of step 3.
2. The control panel message may be: Paper Jam>Tray
3. This FIP may also fix worn turn or feed rollers.
4. Try the front tray first to be sure it is the turn solenoid (in the cassette). Try another cassette
tray. Be sure the feed roller is operating first. Try replacing the turn solenoid before the MCU.
1. INITIAL ANALYSIS
Inspect the following components. Are they compatible with your printer version, correctly
installed, not damaged, deformed, or contaminated?
MCU PWB LVPS Assembly
Turn Solenoid Feeder PWB
Feeder PWB AUX Harness Assembly Tray 1
Harness Assembly OUT
Yes No
Go to Step 2. Replace the problem components.
2. LVPS 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 13–10 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. TURN 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 DG84 to check the Turn Solenoid in Tray 1.
Is there +24VDC between P/J 13–8 and P/J 11–2 on the MCU PWB when
you do not actuate the solenoid in Tray 1?
Is there 0VDC between P/J 13–8 and P/J 11–2 on the MCU PWB when you
actuate the solenoid in Tray 1?
