ERR 06: Self Cleaning Sensor Unit Malfunction. Consult with Canon Service Center

OCT 18 2008

Well, I just switched on my Canon 40D and saw this error "ERR 06: Self Cleaning Sensor Unit Malfunction. Consult with Canon Service Center" on the screen. Wait a minute, what is that I did wrong which lead me to this error. I tried to recall everything that I did in past. On Sunday I took almost 1300 pictures from Chicago Marathon 2008 and while downloading those to my laptop I didn’t follow the instructions given by Canon.

Canon says whenever you use the usb cable to connect your PC/Laptop then turn off the camera before plugging-in and turn off before plugging-out. Turn the camera on only after you plug-in the usb cable. I guess I didn’t follow the instructions properly. I am not a master in photography or in using this camera. I am just a novice so committed to make mistakes here but each lesson will make me better as a photographer.

Here is a solution which I found from this forum, it is a long posting there so follow my instructions and see if it works for you.

  • Turn off Canon 40D Camera.
  • Remove the main battery, it is also advised by the pros from the forum to remove the time battery as well.
  • Turn on the Canon camera after you remove the battery, keep it like that for 5 minutes. Try to take couple of snaps. Motive behind this is to flush all the remaining power in the camera.
  • Turn off the camera and put the battery back.
  • Turn on your Canon 40D and it works now.

Good luck guys! Let me know if this works for you.
