Suggested action: - Check and reseat all cable connections between the E-25C and copier.
- Make sure that the E-25C service switches are set to OFF (both away from ON).
- If the Controller date/time cannot be set or responds slowly, replace the battery on the motherboard [Link to Lithium Battery], and then update the date/time in E-25C Setup [Link to Running the E-25C Setup].
- Shut down and open the E-25C, and do the following:
Reseat the power and data cables to the HDD. Make sure that the data cable is connected to the proper connector on the motherboard.
- Reinstall system software [Link to System Software Installation Procedure].If no airflow or fan noise is evident at the vent holes of the chassis where the chassis fan is located, replace the chassis fan [Link to Fans].
- Replace external cables, one at a time.
- Check and reseat the CPU cooling assembly.
- Replace the CPU cooling assembly [Link to CPU and Cooling Assembly].
- Replace the CPU [Link to CPU and Cooling Assembly].
