A card access error may indicate that an xD-Picture Card memory card is in a write-protected condition. xD-Picture Card memory cards have a special protection feature to ensure that your pictures are kept safe.
During this condition, you can still use the printer for printing and saving photos from the xD-Picture Card to a secure location, such as the computer hard drive.
To resolve this error, try the following:
Reinsert the xD-Picture Card memory card into your camera and turn on the camera. In most cases, the camera automatically makes the necessary changes.
Reformat the xD-Picture Card memory card. See the documentation that came with your camera for instructions on reformatting the memory card. Note that this process erases the pictures currently saved to your memory card. To save these pictures, transfer them to the computer before reformatting the memory card. Once you reformat the memory card, transfer those photos back to the memory card using the computer.
