Relay sensor
Paper feed clutch
• Bypass the turn guide door open sensor*.
• Turn the printer on while holding down the paper relay sensor.
- If the operator panel does not display “Paper Jam”, check
for a dirty paper relay sensor.
- If the paper relay sensor is clean, or the actuator for the
paper relay sensor is broken, replace the sensor.
If the sensors are replaced and problem remains, replace the
printer controller board.
• Check the clutch cables for proper connection to CN8 on the
engine board, and CN20 on the printer controller board.
• Check the resistance of the clutch using a multi meter. The
resistance should measure 192 ohms.
If the clutch shows a significantly higher reading, replace the
clutch.
• If you replace the paperfeed, or transport clutches and the
problem remains, replace the engine board. If replacing the
registration clutch and the problem remains, replace the printer
controller board.
