System error E000 how do I fix it. I tried what it said in the instructions to turn it off for a while then turn it back on that didn't help. Canon NP6025 copy machine.

To delay the 3 second shut down and enable the technician to access service mode; open the front door and pull out the transport unit. Do not actuate front door microswitch. Press the service mode button, enter " * 4 * ", scroll to error clear and clear error code. Machine will automatically turn off power after clear. Power up machine and test.
If the power shuts down after error code has been cleared, the cause of the error has not been corrected. Correct cause of error code and clear error in service mode.
