Hi, thank you for contacting My name is***** will do my best to provide the right answer to your question.
That is a mechanical-malfunction-in-camera message.

The camera will most likely require repair. (If it is less than a year old, and none of the following have happened, the failure is covered by warranty and the repair would be free in that case.)

How old is the camera? in months or years since you bought it.

Has the camera been dropped or otherwise subjected to mechanical shock(s) in its lifetime?
Has the camera been operated in or subjected to, temperatures below 32 degrees F (freezing point) or above about 100 degrees F ?
Has it ever been subjected to a humidity higher than 85 % or gotten wet ?
Has the camera been operated in a gritty or sandy environment, such as a beach, a seaside, a construction site, or the like?


Try removing the batteries, and leaving the camera on a (dry, non-humid, non-dusty) shelf for overnight. Then put the batteries back in and try the camera again.


After that, if the error persists, then you need to have the camera serviced - hopefully for something minor like a little jamming of one motor's gears or the like.

Repair may be engaged by going to

or by calling 1-800-OK-CANON.
