Something with grounding.Try with other outlet and inspect drum and developer grounding also.

Re: canonIR1022A Error Code E197

Erroneous communication between the DC controller PCB and image processor PCB was detected.


- Check the connectors of the DC controller PCB and image processor PCB.
- Replace the DC controller PCB for normal connection.
- Replace the image processor PCB.

Below are two examples of where to place your meter leads to measure ground to neutral on 120VAC wall outlets.
120v at +-10%

Through experience it has been determined that less than .5 volt AC should be measured between ground and neutral.
If absolute zero is measured then it may be an indication that the ground is not connected or that some other problem may exist within the outlet.

Outlet readings utilizing a "hand held" circuit meter are only a "snapshot" of the voltage at the time of the reading. Fluctuations, spikes, surges and drops in voltage sometimes require a long term reading such as can be achieved with a line monitor.


if ground to neutral is over 0.5v u need a electrician-----------------
