2 Note:

CF Type II
Memory Stick/PRO, SD/MMC and xD-Picture Card shares the same slot. When cards are inserted in the two slots at once, the slot which will be accessed first is determined according to the priority shown in the table. To select a card that has been inserted in a non-active slot, first remove the card in the active slot. In memory card direct printing mode, the image files in the active slot are valid and have assigned frame numbers. The number of images will not change if a card is inserted in another nonselected slot. When the card inserted in the slot is accessed from the PC, only one drive is displayed at a time as a removable disk* and only the card that is in the active slot can be accessed via the removable disk. A card that has been inserted into a non-selected slot cannot be accessed. (This is for Windows. For Macintosh, the card in the active slot will be mounted on the desktop.) Does not support 5V type of memory cards. When a memory card is being accessed, do not touch the memory card. For detailed information on the supported file system and formatting the memory card, refer to 1.7.2 Memory Card Direct Print Function ( p. 31 ).
