• Code: OF 99-4
• Description: Generic Solenoid/Clutch Solenoids and electric Clutches are essentially electromagnets. Typically, a positive voltage is applied to one end of a coil, and a current driver is connected to the other end. Control Logic switches this driver to GND potential, actuating the magnet. Bi-directional solenoids have a bipolar driver connected to each end. One leg is switched to 24 VDC and the other to GND.
• Remedy: Ensure that there is no damage or binding in the solenoid or in any mechanical linkage. If there is an Adjustment for the clutch or solenoid, make sure that the procedure was performed correctly
  The Clutch/Solenoid is always energized. Y↓N→Enter Service Diagnostics Menu: Printer Menu > Troubleshooting > Service Tools > Printer Status Page >hold the Up and Down buttons simultaneously > Run Service Diagnostics > OK. Perform the Clutch or Solenoid tests. The Clutch or Solenoid energizes. Y↓N→There is +24 VDC between the switched leg (J543 pin A6 in the example, ) of the control PWB and GND. Y↓N→There is +24 VDC between the powered leg (J543 pin A7 in the example, ) of the control PWB and GND. Y↓N→Disconnect the connector (J543 in the example, ). There is +24 VDC between the powered leg of the control PWB and GND. Y↓N→Refer to the 24 VDC wirenets. check the input power to the control PWB. +24 VDC is present. Y↓N→Use the 24 VDC wirenets to troubleshoot the problem. Replace the control PWB. Check the wire in the powered leg of the circuit, (J543 pin A7 in the example, ) for a short circuit to GND (refer to Engine Control Board (MCU PWB) Plug/Jack Locations ). If the wire is OK, replace the clutch or solenoid. Disconnect the connector (J543 in the example, ). Check continuity through the two wires and the Clutch or Solenoid. There is less than 100 ohms between the two legs of the circuit. Y↓N→Disconnect the Clutch or Solenoid. Check continuity through the two wires and the Clutch or Solenoid. There is less than 100 ohms across the clutch or solenoid. Y↓N→Replace the Clutch or Solenoid. One of the two wires between the control PWB and the Clutch or Solenoid is open. Repair or replace the wiring as required. Replace the Control PWB. There is less than 1 VDC between the switched leg of the control PWB and GND. Y↓N→Replace the PWB. Replace the Clutch or Solenoid. The clutch or solenoid appears to be functioning correctly. Refer to the Circuit Diagram for the RAP that sent you here. Check the wires for loose connections or damage that may cause intermittent operation. Perform any required adjustments. There is a short circuit on the switched leg (J543 pin A6 in the example) from the solenoid or clutch. Check the wire for a short circuit to GND. If the wire is OK, replace the solenoid. If the problem persists, replace the controlling PWB.
