Canon camara was dropped and now it reads e18. Camara still shows pictures on the display screen


The Canon E18 error happens when the lens gets stuck while trying to extend. When your camera was dropped the lens mechanism was damaged resulting in this error for a jammed mechanism.

If the camera is still under warranty you should see if Canon are willing to repair it. If not you can view this link which is a very good walkthrough with pictures on how the error was resolved with a Canon SD300.

As you can see from this the process is intricate enough and involves opening the camera so should only be attempted if you feel confident about taking it on.

Hope this helps. Please remember to rate my answer. Many Thanks.

Cannon SD300

hi innasha,

try the following:

make sure your Canon has fresh batteries and it is in recording mode.

1) Remove the batteries from the camera, wait for a couple of minutes,then put them back in and turn the camera on.

2) Try compressed air. With a fine tip blow off gun and drycompressed air (20 lbs) set the tip between the lens turret and thecamera body and turn on the air while moving the tip around the lens.It should remove all dust and sand. Turn the camera on and it shouldfunction fine.

3) Another method is to tap the padded USB cover part on a hard surface, for example, a desk. It sounds so simple, but veryoften in works.

4) Try forcing the camera lens:

Turn off the camera. Place it on the back with the lens facing up and take a look at the spacing between the lens and the lens housing. If you notice that the gap is not even all the way around the lens, the problem should be easy to fix. This type of a problem usually occurs if the camera was dropped while the lens was extended.

Simply - VERY GENTLY - press down the lens on the side where the gap is the biggest. You should hear a "click" as it pops back into place. Try powering the camera back on.

If the lens doesn't extend at all or it extends, and then retracts again, do the following. Turn the camera off. Take the camera in one hand and with the other gently take one part of the lens and gently move it round in a circular movement. Do so with both sections of the lens. You will hear a "click" as it pops back in place. Power the camera on.

Another version of this fix would be to pull and twist on the largest ring of the lens while turning the camera on. Listen for a "click". If at first the focus seems to be off, turn the camera on and off and take lots of pictures, close ups and distance. Focus should slowly start improving.

there is a guide to dismantle it with pictures: try it:

good luck!

E 18 problem

Your first problem sounds like a defective CCD imager. If your camera was an S300 Canon should fix this for you for free, including free shipping both ways. Please check the following two links for more info:
Applicable cameras include:
A40, A60, A70, A75, A80, A85, A95, A300, A310, S1 IS, S60, S200, S230, S330, S400, S410, S500, SD100, SD110

Unfortunately, you mention that your camera is an SD300. That model camera is not currently on the recall list. But you might want to call Canon anyways. You might get lucky as the problem sure sounds familiar to the recall (excuse me, advisory hehehe).

As for the SD500 with the E18 error, try

Camera will take pictures but they are all black.

Your CCD is damaged, OR your aperture is stuck closed in your lens. Turn on the camera, have the lens extended and look into it, do you see a small circle at the bottom that looks like an opening? If not your aperture is stuck and you need a new lens. If its open, your CCD is bad and needs to be replaced.
