Question about Canon PowerShot S400 / IXUS 400 Digital Camera
This error is cause by a few things. First you need better power, how old is the unit? The battery pack may need replaced, the lens mechanism draws alot of power and sometimes if the flash is charging and the lenses are moving it struggles for power and shuts down. Another thing that can cause this error is jammed gears in the lens. This can be cause from an impact (dropped unit) or debris in the lens mechanism (sand, dirt, dust) the gears are so small and as is dust anything can blow in there and get jammed in the unit to jam it. I have got units to function again by tapping on the front of the lens while repeatedly tapping on the front of the lens. The idea is to work the jam out and free the lens. The E18 means a stuck lens but the reason its stuck i canot tell with out looking at it. Tap on the front of the lens (the part that moves in and out like a telescope) or try and tap on the side while powering it on. If you know some one with a unit like yours try their battery before you get a new one. They are very power hungry and if your unit is a few years old it may be time for a new battery.

I managed to get life into my Canon Powershot S70 by tapping it quite violently while holding it with the lens down, and forcing the lens out : ). I was almost on my way to can it. It works fine now.

I am getting an E18 message on my camera screen, what does it mean and can I fix it?

Yes! Mine was the same way but I knocked on the lense with my knuckle as it powered up... and it came back to life!

Although I we recently had the camera at the beach, I was able to get it to work with a new set of batteries. I also feel it may be a combination of that (the batteries) and posibly some debris (sand).

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.
