Abstract
In the preferred embodiment, an interlock switch is located on a first of two access doors of a printer. The second access door has an upwardly extending protuberance near its end. The switch is actuated for enabling the system by closing the second access door followed by closing the first access door. The protuberance on the second access door pushes upwardly on an arm of the switch as the first access door is closed, thus actuating the switch. This not only provides a reliable safety mechanism by insuring that the doors are properly closed, but eliminates the cost of a separate safety interlock switch for each access door.
