How to take apart a canon mx860

[pearlhouse]

Accidently a dime got dropped into the cartridge area on my mx860. I believe it fell to the bottom of the printer, so I just left it there and the printer has been working just fine. The last time i moved the printer I think the dime got stuck some place in one of the mechanisms and is causeing the printer to squeel and stall. Im looking for instructions on how to dis-assemble the printer to a point where I might have access to the inners so I can retrieve the dime and maybe unjam the printer. I started to take apart on the b ottom of the printer but Im not sure where to actually begin dis-assembly. From previous experience I know these things are snapped together with plastic fingers that snap and lock some of the parts in place. I dont want to break any of these off by prying in the wrong places.
