Lifter alarm
Cause:
- Deck Lifter Motor alarm
- The lifter cannot be lowered.
Detection condition/timing: The Bottom Sensor or the Relay Sensor was not turned ON within the
specified period of time when lowering the lifter.
Movement/symptom:
While failure has occurred (an alarm has occurred), the target paper source cannot be used
because it is in no paper state.
Measures:
- Forcibly open the receptacle and check for any foreign matter in it.
- Check that the Lifter Plate is not caught by the Side Guide.
- Remove the Front Cover, and check that the lifter wire is properly installed (no coming off,
disconnection, slack, or winding in the reverse direction).
- If there is an error, repair it and close the receptacle.
- Execute service mode: COPIER>FUNCTION>CLEAR>DK-RCV.
- Execute the recovery command, and check that the Side Deck is initialized properly.
- Push the Paper Supply Sensor and check that the Lifter Plate being lowered stops at the lowest
position.
1) If it is not lowered:
- If it is not lowered and no motor drive sound is heard, check for improper connection of the
connector of the Relay PCB.
- If it is not operated after checking the connector connection, replace the Relay PCB and the Lifter
Motor in that order.
2) If it is lowered:
- Check if the Lifter Plate stops at the bottom of the receptacle.
