Note: The voltages for the magnetic clutch can
be checked at the 6 pin inline cable connector
located in the HVPS to engine board cable
harness above the temperature/humidity board
assembly on the left side of the printer.
Check the resistance of the magnetic clutch, it
should read approximately 245 ohms. If
incorrect replace the magnetic clutch.
Check the following voltages on the inline
connector while feeding a sheet of paper.
Pin # Voltage Static Voltage Feeding
1 (Black lead) +24 V dc +24 V dc
2 (Red lead) +24 V dc 0 V dc to +24 V dc
If the clutch or cable from the clutch are open:
1 (Black lead) +24 V dc
2 (Red lead) 0 V dc
If the voltage on the red lead measures
approximately +24 V dc, but does not vary as a
sheet of paper is picked, check the cables.
• If correct, replace the failing cable.
• If correct, replace the engine board.
