Canon E18 Error: Repair Instructions
Welcome to the Canon E18 Error: Repair Instructions
PLEASE POST YOUR EXPERIENCE BELOW! IT IS IMPORTANT THAT WE BUILD AS LARGE A LIST OF STORIES OF PEOPLE EXPERIENCING E18 ERRORS!!!
Thankfully I haven't encountered the dreaded E18 error with either of my Canon cameras (the A70 and A75), but if you did, I have several pieces of information that can help. Before you try any of the suggestions below, make sure the camera has fresh batteries and that it is in picture taking mode.
First, try hooking your camera up to the TV with the included A/V cable. Rumor has it that this resets the E18 error! (Thanks SLF)
Second, 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 sand and dust. Turn the camera on and it should function fine. (Thanks Sprocket)
Third, try the tap method. Tap the padded usb cover part on a hard surface (e.g. a desk). (Thanks Tania, et al)
Fourth, try forcing the lens.
Version #1:
This error occurs when the lens is "stuck" or not extending "straight". The error can happen in 3 ways: either when the lens wont "come out", or "comes out" and then retracts, or does not retract at all. 1) If the lens doesn't extend at all or it extends, but then retracts again, do as follow: Turn the camera off. Place the camera on it's back with the lens facing up and have a look at the "spacing" between the lens and the lens housing. You'll probably notice that the gap is NOT EVEN all the way around. To fix this, simply -VERY GENTLY- press down on the side where the gap is the biggest. You will hear a "click" as it pops back in place. Try powering it back on. 2) If the lens is extended all the time and won't retarct at all, do as follow: Turn the camera off. Take the camera in one hand and with the other gently, in turn, take the two 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. (Thanks Mike Scher)
Version #2:
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. You may find that the focus seems to improve. (Thanks Jeff Kishiyama)
