I am getting error 99 on my camera - Canon EOS Rebel XSi


This camera is used for the past 4 years. Never faced any isses. Suddently started getting the error 99, "Shooting not possible. Turn the power switch to <OFF> and <ON> again or re-install the battery".


the following are tried:


Removed the battery, fully charged it again

Changed the SD Card

Changed the Lens

Removed the battery, lens and SD card and kept the camera idle for 20 minutes just clicked with out SD card.


No changes. 


these I did not try


Change the battery pack to see if it helps, no back up battery with me

Did not update the firmware since I bought the camera in 2009. I do no know if it is available for my model.


Any help/suggestions are welcome!!

Hope this helps!


"Change the battery pack to see if it helps, no back up battery with me"


You need a different, preferably new, battery as the error may be the battery. Also the battery must be out of the camera for a long time, a few hours or so.


"Did not update the firmware since I bought the camera in 2009."<-----This is not the error.



You must clean the lens contacts. And, or, try a different lens. While you are at it get a brand new high quality SD card.

EOS 1DX and 1D Mk IV and several lenses!

My experience with error 99 is that it seems related to a component trying to draw more current than it should. To prevent that from happening, which could damage the component either from heat or overstressing a mechanical part the camera shuts down & gives the error code. A weak battery can easily be at fault but so can a lot of other things.

I agree... the first thing you should try is a fresh battery. A four year old battery might be on it's last legs (probably depends upon how many times it's been recharged.... and how deeply it was discharged in between charges).


If possible, it would be good to also try a different charger. Sometimes they go bad.


Does your camera have a separate replaceable date/time battery? If so, it might be a good idea to replace that, too. Those types of batteries usually have roughly a five year lifespan.


Wouldn't hurt to update the firmware. If' it's never been done, very likely there is a newer version. Even if it's not an update, it might be a good idea to reinstall it.


HOWEVER, before you attempt to install a firmware update, you must have a reliable, fully charged battery. You don't want to have a camera shut down halfway through a firmware installation. That's almost guaranteed to "brick" the camera. So sort out the battery first, to be certain you don't have problems there.


The reason for replacing the firmware is it might have become corrupted. It's essentially an operating system for the camera, which is essentially a computer... and "stuff" happens, as we all know, to computer operating systems! Sometimes a reinstall or update will correct problems in the software.


Canon's and ebiggs instructions above about "rebooting" the camera are a good idea too. In fact that's the first thing I'd try, since you don't need anything to do it. The reason you "reboot" is to clear any lost data strings from the memory, that might be interfering with the camera's operation. Again, it's a lot like a computer.


A little more about rebooting the camera... If your camera has a date/time battery, in addition to the main, rechargeable... remove both of them. Rather than letting the camera sit, another method is to turn the camera on without any batteries, and press the shutter release button once. It won't fire, of course. But this should drain any remaining charge from the circuit immediately and is faster than waiting for the residual charge to drain off slowly.


Once you have done this (or let the camera sit for 20 minutes or several hours without the battery), go into the menu and see if the date/time needs to be reset. If so, you got a proper reboot.... If not, try again.


In addition to trying a different memory card, always formatted in the camera, also inspect the slot the card fits into carefully. Look at it with a flash light, to see if anything looks damaged, shorted out or if there is any obstruction. Probably not something you can fix yourself, if there is a problem.


I agree about cleaning the lens to camera contacts. I use a few drops of isopropyl alcohol on a clean, lint free cloth. That's to remove any oils (finger oils, or lubricating oils from inside the lens or camera). Just keep off the mirror in the camera and the lens optics.


You also might use the same to clean the battery contacts both on the battery and on the charger (unplug it) and inside the camera. Wipe down the date/time battery, too.


None of the above is certain to fix the problem, but all are fairly easy and free or relatively inexpensive to try.


If none of the above works, then send the camera in to Canon and have it checked.

Thanks for the responses from each of you!


Today I have taken the camera to 'Hunt's' shop very fameous canon dealer in Boston, MA. The tried with a new battery and also different lens, I get the same issue. 


The camera is in allow clik without SD card and it error even without a lens. So I am ruling out the lens, battery- old & new, camera contacts with lens(I cleaned it by myself & Even the canon expert in the shop). 


I have decided to send it to Canon service center in NJ. I have to pay 190$ and then ship it to them. I will have my fingures crossed. Lets us see
