The present invention provides method and apparatus for supporting a legacy application programming interface set between a component and a color management system. Insertionextraction directions of the card edge connector are substantially perpendicular to at least one of the first direction and the second direction. Movement of the filter housing in a first direction relative to the mounting structure as the first and second sloped portions bear against each other results in the movement of the filter housing, and thus the dirt cup, in a second direction transverse to the first direction relative to the mounting structure.
