My camera displays an e18 on its screen when i

SOURCE: E18

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.

E18 indicates a lens or "optical unit" problem. In other words your zoom lens won't function correctly. Canon will be more than willing to look after you.

Lens errors (aka E18 errors for Canons) 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's some things that you can do to try to correct it. They only seem to work for less than 50% of the lens errors, but if the camera is out of warranty, they're worth a try:
