How To Troubleshoot Canon Copy Machines (7 Steps)

1. Check that the power cord is securely plugged into the wall outlet if the copier will not turn on. Make sure the power switch is turned on.
2. Remove any jammed pieces of paper from the copier. Turn the unit off and press the top cover release button and open the cover. Check for any jammed pieces of paper and remove. Open the cover on the machine's left side and check in there as well. Turn on the copier and check to see if it functions normally.
3. Check to see if the top cover has popped open if the power turns off during copying. Make sure that the left cover is not open. Press in the middle of the left cover to close it securely if necessary.
4. Remove the sealing tape from the toner cartridge if no image appears on the copies. Adjust the copy exposure. Press the 'AE' key to switch to manual exposure control mode. Adjust the exposure level by sliding the exposure adjustment lever. Slide the lever to the right to darken the image and to the left to lighten the image.
5. Distribute the cartridge toner evenly if there are white streaks on the copies. Turn the copier off. Remove the toner cartridge from the copier and rock it left to right at a 90-degree angle a few times. Insert the cartridge back into the copier. If the white streaks continue to appear, replace the toner cartridge.
6. Clean the fiber lens if dark bands or black streaks appear on the copies. Turn off the power switch and unplug the copier. Slide the platen to the left to expose the lens. Run a cotton swab over the entire length of the lens several times. Clean the reverse side of the fiber lens. Open the top cover and remove the cartridge. Clean the reverse side of the lens by running the cotton swab over the lens several times. Replace the cartridge and close the cover.
7. Allow at least two hours for the copier to warm to room temperature if the copies are too pale. Allow the same amount of time if the copies are completely black. It could be that condensation has formed inside the unit. This can sometimes happen when there is a sudden change in temperature.
