The E18 error is an error message on Canon digital cameras. The E18 error occurs when anything prevents the zoom lens from properly extending or retracting.
The error has become notorious in the Canon user community as it can
completely disable the camera, requiring expensive repairs.
A quick internet search for "E18" + "canon" quickly reveals hundreds of similar complaints.
ConsumerAffairs.com reports that the "lens has a feature called bellows claw, which is a gear that physically extends and retracts the lens. A piece that holds the lens, the barrier plate, is not large enough and can sometimes cause the bellows claw to malfunction, resulting in a stuck lens". The result is a black screen that only contains the error message, E18. Another problem mentioned on the site blames a sticky iris in the lens, caused by grease entering inside from the microphones built into the lens. The buildup freezes up the ability of the lens to open.

SOURCE: Error E18
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.
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

The E18 error is related to the LENS not able to retract fully. If it is still under warranty, I would advise you bring it to the nearest service center. This is to avoid further damages. Otherwise, you can try a few things below.
There are a couple of things you can do.
1. Turn it on and then off. Spray canned air around the lens.
If trick 1 will not work out, try this.
2. Make sure the battery is fully charged. Turn on the camera and then give it a couple of firm whacks on the side. Make sure nothing is blocking the lens and wait for it to fully retract.
Let me know how it goes.

The problem is that the lens has become stuck in the barrel. There are some DIY solutions you could try, but the probability is that you will have to get it fixed by a professional.
Use these at own risk as it may further damage the camera.
Firstly , try connecting your ac adapter or usb cable.
Try holding the shutter button while switching on the camera.
Look at the lens , and if some of the lens 'circles' is misaligned or not concentric then try wiggling it (while holding camera lens down).
Try gently pushing or pulling the lens when it extends but this is risky as it may cause the lens barrel to slip out of its guidance system.
Another way to do this is to place the camera lens down on a hard surface and then power it up. Be sure to use a soft cloth or something similar as to not scratch your lens or casing. Let the lens push the camera up and down a few times and sometimes the little resistance provided by the camera is enough to get things going again.
Try hitting your camera near the lens on the body with the soft tissue on the palm of your hand.
Other than that , I would take the camera to a repair center for a evaluation to see if it would cost more to repair than to replace the camera.
If it is still under warranty I would suggest you take it in before trying any of these steps and remove any off-brand batteries or accessories as some stores are really fussy about warranty repairs on camera's with non-brand accessories.
Hope the advise is useful.
