This might sound very silly but you just never know.....
I was cleaning my sensor (on a 30D) with a rocket blower and when finished I forgot to turn off the camera as the manual recommends. I proceeded to attach my lens with the sensor still in the 'clean' position. I quickly realised and tuned the camera off, thus flipping the sensor back to its normal position. Although I can't see this having any detrimental effect (apart from further dust with the sensor being exposed - after the incident I repeated the whole cleaning process to make certain) I'm not entirely sure. Can this cause any physical damage to the camera?

Yes, sorry, I meant the mirror, which flips to reveal the sensor behind it.
As far as I know, damage is almost impossible because the mirror is tucked away in the camera body for sensor cleaning and the sensor itself is located too deep. In addition, the lens doesn't have any parts which even come close to protruding into the body through the lens mount. I reckon I should be safe but wanted to know if anyone knew for certain.
Cheers for the replies so far - if anyone has any further info please let me know.
