This isn't necessarily related to the stuff going on right now. i have seen that message in the past. It could be a problem with the scanner/printer on the deposit slot, no need to shut down the entire machine if it can still do other transactions. If you went to several atm's and got that message, then there might be something bigger going on.

I would think they would want all the funds coming in they could get... unless it was the government telling them they can't accept deposits.
