By providing the robotic element (20) with a 2-D optical sensor (86), a common image processor may be provided having multiple functions. By using a 2-D optical image processing system, the control system of the apparatus may easily be adapted to read various types of data presentations, just as actual images for sections of the apparatus may be identified in order to assess the condition of the apparatus. The optical sensor may be used to automatically identify the slides and the reagent containers present in the apparatus, just as the optical sensor may be used for checking if a slide is misplaced at or absent from a slide position, etc.
