An ATM apparatus having a bulk sheet acceptor. The sheet acceptor is mounted in movable relation relative to a chest portion of the ATM. Access to an interior of the sheet acceptor for servicing may be made through an access opening. A service cover may be mounted at alternate mounting sites of the sheet acceptor housing in order to close the access opening. The interior of the sheet acceptor may be accessed by pivoting the cover on a set of tabs engaged in corresponding slots, or by selectively lifting the cover away from the tabs. The cover may be replaced by engagement of either a first set of tabs with corresponding first slots, or a second set of tabs with corresponding second slots.
