Understanding the Error Messages
Once you are familiar with the types of errors that can occur while
you’re using the PhotoCapture Center
™ , you can easily identify and
troubleshoot any difficulties.
When an error message appears on the LCD, the MFC will beep to
get your attention.
Media Error — This message will appear if you insert a media card
that is either bad or not formatted, or when there is a problem with
the media drive. To clear this error, take out the media card.
No File — This message will appear if you try to access a media
card in the drive (slot) that does not contain a .JPG file.
Out of Memory — This message will appear if you are working with
images that are too large for the MFC’s memory.
