Canon A530 lens cover

hello, the lens will not open for the following reasons
1. if the battery is dead, replace or re-charge the battery or use a a/c adapter if available
2. dust in the crevices of the cover, bang the camera with your hand gently this will dislodge the dust and cover mechanism will become free, you may also tap the cover with your forefinger on lens edge, take rubber bulb blower , blow air thoroughly in the crevices of the cover
hope it helps and your camera works

Digital cameras with shutter covers sometimes jam, keeping teh cover from retracting and the lens from extending. That is what is giving you the message. You may be able to assist it by gently pushin it open when you turn on the camera. Key phase there is "gentle". Do not force it open as you may permanently damage it. If the motor is locked up or the lens cover still refuses to open, take it to a camera shop for service.

This kind of problem occurs if camera dropped on floor that broke lens mechanism OR lens mechanism got dust particles that make it stuck.
Usually lens mechanism needs to be replaced to solve the issue, however, user level try to solve the problem is to tap camera on your palm a few time gently that may release stuck lens mechanism and it start working again, if that does not help then lens assembly will be replaced.
Thanks.

You may try to gently force it open as something may have gotten on the lens cover itself 'pop/derbies' thinking out loud or if you have accidently dropped it on it's cover there may be an obstruction or bent lens which may be preventing it from opening.
Better to force it open and keep it open that have it stuck closed.
By the way if it's still under warranty. Take it or send it in right away so they can fix it for free. You may pay some gas money or shipping but hey it will be fixed.

easy fix. yo turn it on and then very lightly tap the lens cover or push it out. then you should clean the lens because the dirt or dust on the lens is stopping the lens cover.

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.

Please read carefully below procedure how to remove "Barrier Block" (what you call Lens Cover)..
Turn camera power ON so Lens will extend.
Take out battery so lens will remain extended.
First silver ring needs to be removed with help of tweezers as shown in below image..

Now you will see 2 screws at front of lens, unscrew to remove barrier block (lens cover) as shown in below image..



You need to have new barrier block with following part number..

A-1205-001-A BARRIER BLOCK ASSY

Subject part is available in Part Store

Install new barrier block as shown following image..



Insert battery and power up camera to check does barrier block works fine.
Need further info, let me know.
Good luck.

I recently had the lens cover stick partly open.  There are 4 segments to the lens cover, and if we number them from the top, number 2 was not closing.
I gently flicked the segments a few times, in case there was a grain of dirt causing it to stick (although the camera has never been in a dirty or dusty environment).  This caused the lens cover to close fully each time, but now it would not open fully, segment 1 would not open, although it would stay open if moved by finger.
Anyway, after a bit of fiddling, I got it working properly again.  The way that the lens cover appears to work is that only segments 2 and 3 are pushed open or shut by springs, segments 1 and 4 are pushed open and shut by tiny tabs that catch on segments 2 and 3.  If the segments somehow get pushed out of alignment, then they either bind (causing the cover not to shut), or they get disconnected (causing the cover not to open fully.
Now I am not sure exactly what I did to get the mechanism form the stuck open state to the not opening state, but from there the way to fix it is to:
-With the lens open...
- Hold segment 2 in the closed position with firm finger pressure (which will tend to push it towards the lens).
- Push segment 1 towards the open position until you can see that it has cleared the edge of segment 2.
- Lift segment 2 way from the lens so that it will rub past segment 1 as you...
- Move segment 1 to the open position.
- Repeat if necessary to get the technique right.

I can't provide any guarantees, and I am not about to repeat the excercise on my camera, but it was a lot easier than sending it off for repair.

Try blowing lots of compressed air around the open lens shutter to clean the mechanism. Or use a hair dryer for a few seconds (don't want to heat up the camera). Also with the lens barrel extended and pointed downward, tap the lens barrel with a pencil while you extend and retract the lens by powering the camera on and off. A grain of sand in the mechanism is usually the culprit, and you want to try to dislodge it.

You can open it up, but only as a very last resort. The above procedures usually work if you try them enough. But for those particularly nasty stuck mechanisms, here's an example repair on a Canon Powershot A400 (do this at your own risk, and be aware this will void your warranty):
