E18 error message
This is a common error with Canon PowerShot cameras. This error occurs when anything prevents the zoom lens from properly extending or retracting.
There are several methods you can try to solve this problem.
First method: Remove the battery from the camera and wait a few minutes. Place in a new battery and turn the camera on.
Second method: This is similar to the first method. Remove the battery and then remove the memory card. Insert in a new battery and then turn on the camera.
Third method: Hit the side of the camera (with the rubber USB cover) lightly on a hard surface to knock out any particles that may be jamming the lens. Hitting the camera too hard may damage it further.
