You don't want to take it apart. Wayyyyyy too many parts and steps. I bought a used one with the same problem, lens was stuck half open and out of alignment, it was dropped. I got it working well in about an hour.
I tried all the described tricks, plus a few others.
#1 get a strong canister vac or shop vac, and put the end of the hose right over the front of the camera and turn it on for a few seconds, and turn it lens side down. This will remove any grit in the gears and may pull the lens itself all the way out.
#2 if the lens is still stuck try rotating the outer collar gently both ways until you hear it click into place. If it does, look at the alignment of the inner barrel to the case. the lens will never fully retract if it is out of alignment, if it is you will have to force it back onto the gears it should be on.
If it was dropped resign yourself to the fact you must at some point nearly break those plastic gears inside to get them back where they need to be, and there's a fine line between forcing and breaking it.
Just remember you'll have to get the lens closed and aligned before it will work, closing it is a proces of both rotating the outer collar and gently wiggling the inner sleeve closed. Before it will close it has to be straight. Once it its closed put a fresh set of batteries in.
This whole E18 issue is not as complex as people might think, you just have to be reeeeal gentle with that lens assembly when it's extended.

Camera gives E18 error!!!


Hello there,
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.

Lens wont extend, lens error restart camera


My wife's Canon SD200 got stuck with an open lens and the E18 error. I opened the case and wiggled things and still nothing. Then, I turned the camera on and started tapping the edge of the lens casing with the magnifying glass I'd been using (need the battery and memory chip in place and make sure you've transferred pictures to your computer before trying this). Voila! The lens closed. But, of course, it wouldn't open and still gave the E18 error. Well, one good tap deserved another and Voila! again. It opened. After a few more iterations - and cleaning the lens casing each time, it was back to normal. The trick is the timing of the tapping. Just after turning on the power to the camera start tapping on the lens casing - not hard - just a light tapping. And don't tap on the glass lens itself -- you don't want to really break it.

E18 error on canon digital camera s200 powershot dropped it and now the lens is stuck halfway out/in The lens will not open, it was not dropped. I get e18 error.


Canon Powershot's error E18 has to do with the lens:
If it appears on a black LCD with E18 written on the corner, it is mostly due to the lens getting 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.
I am giving below a link which will help you with E18 problem.

Hope this helps, let me know if you have a proble.

You can Try the following also;
Remove the batteries from the camera, wait a few minutes. Put a fully charged batteries back in and turn the camera on. if it doesnot work then,

2: Remove the batteries again, as also remove the memory card. Then install the newly charged batteries, when you turn it on it should come back to life.
3: Insert the cameras Audio/Video (AV) cable, and turn the camera on. Inserting this cable ensures that the camera's LCD screen remains off during the start process. Thus extra battery power is available to the camera's lens motor during start up. This extra power can be useful to overcome any grit or sand particles that may be jamming the lens.
4: Place the camera flat on its back on a table, pointed at the ceiling. Press and hold the shutter button down, and at the same time press the power-on button. The idea is that the camera will try to autofocus while the lens is extending, hopefully seating the lens barrel guide pins in their slots.

Try the above and let me if its any help.
Please do rate and thanks for using FixYa and Best fo luck to get you camera out of E18!

E18 error on Canon ixus40 - lens stuck


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.[1] 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.

Canon PowerShot SD200 E18 Error


The "E18" error code indicates an error that involves the lens unit or lens cover. The grinding noise you hear-to my regret- means that len's mechanism is malfunction. This type of problem could be fixed by professional only.
