    Why viewer does not appear when I connect USB to Casio Projector?

      If the Viewer does not appear when you connect a USB memory device to the Casio Projector's USB port, it could be due to the USB memory's format or the projector's Plug and Play setting. First, ensure the USB memory is formatted as FAT or FAT32 by connecting it to your computer and checking its file system. If it isn't, reformat it to FAT or FAT32. Also, check the projector's Plug and Play setting; if it's set to “Off”, change it to “On”.

    Why digital camera memory contents do not appear on Casio XJ-A251 Projector?
    • A
      Arthur LynchSep 3, 2025
      If the digital camera memory contents do not appear when you connect your digital camera to the Casio Projector via USB, the digital camera’s USB mass storage class setting may not be configured correctly, or you may need to perform some operation on the camera. Consult the user documentation for your digital camera for information about the required settings and operations. It is also possible that the digital camera may not support USB mass storage class. If it does not, you will not be able to use Viewer to view digital camera memory contents.
