A520 - how to do an E18 repair?

Lens errors are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended ...Here are some troubleshooting steps that you can try that may (or may not) correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty (or repair cost approaches that of the camera), they're worth that try. Some of the later steps do involve some risk to the camera, so carefully weigh your options before deciding to conduct them.
And by coincidence, here's me going through the steps using an A520 as an example in this video:

E18 error is common error if the lens is broken already

bring your camera to the nearest repair center

It is a flaw well know by users of Canon Powershot and Ixus cameras and is currently not acknowledged by Canon as a flaw in camera design.


HOW IT ALL WORKS:

Canon E18 error happens when the lens gets stuck while trying to extend. The camera will beep a few times and the LCD will display a little E18 in the lower-left corner. The lens gets stuck in the extended position, and refuses to move either to focus the lens or to retract when powered off.

Apparently, people who posted about this incident on forums say they had to send the camera for repair and that Canon has horrible customer support and response time.

Here is how the E18 error looks like. You just get a black screen with small "E18" sign in the lower-left corner:



The problem usually happens because dirt or sand get into the lens mechanism. But it seems that more and more people are showing, who took great care of their camera, and still started receiving E18 errors.

Instructions

If your camera is still under warranty, the best thing you can do is to take it to the nearest official Canon repair shop and Canon should fix it for free.

If your camera is out of warranty, or if Canon refuses to repair it for free (happens sometimes if for example they suspect the camera has not been treated properly) you can try some of the methods listed here to repair it yourself. These simple methods have helped a lot of people fix their cameras.

Before trying any of the suggestions, 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 dry compressed air (20 lbs) set the tip between the lens turret and the camera 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 should function 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 very often 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.

5) If that doesn't work, there is an online guide for dismantling Canon cameras and fixing the E18 error. (NOTE: Try this only if your camera is no longer under warranty!) It is a great guide with pictures and it can be found at

it is a mechanical problem already and you cannot dismantle the unit by yourself unless you are trained on how to.

E18 Error Fixed Canon PowerShot A520 My lense would not come out and would give me the E18 error and shut down.

I just pressed the power button on and held it down while extending the telescopic zoom lense. It made a horrible sound but the next thing I knew the lense extended out and the camera worked again!

ah ok

The better solution is to send it to Canon's service people.  They can fix he problem is the fixes at the above site won't work.

The E18 error message relates to a problem with the zooming mechanism (lens would not retract or extended) Press the power button on and hold it down while extending and twisting the telescopic zoom lens. It might fix your problem. In any case it could not make it worse Good luck!

Tab on the camera. E18 is a stuck lens. This is common on this camera. I'm not saying this will fix it, but don't break it.
