Why does my Konica Minolta BIZHUB C20 All in One Printer say 'File format is error! Please select valid format!'?

The 'File format is error! Please select valid format !' message on your Konica Minolta All in One Printer indicates that the format of the file name list is incorrect. Check and ensure the format of the file name list is correct.
