My Caonon D761 was showing sytem error E000. I tried unplugging it for a few minutes, a few times, over a number of days, and it still won't reset itself. Can you tell from the error code what the problem is? Gary

Hi,
This code usually means that you have a fault in the heater circuit for the fixing assembly (Heated rollers)
Either the heater element has blown, there is a fault with the Thermister, AC driver, DC power supply, DC Controller or the safety thermal fuse has opened.
The DC controller locks the device for safety reasons, It indicates this error when the temperature sensor detects no change in the temperature of the fixing rollers after 30 - 40 seconds on turning on the heater circuit.

If you are not competant in repairing copiers, you should have a service technician fix this.
