Hello! My name is*****
I can help you with the issue you described, but first, let me know the following:
By "SanDisc", are you referring to a memory card that you plug into the printer in order to print from it? Also, are you able to print from a computer?
Let me know,
I am sorry, but I cannot call you at the moment.
May I know if any other device, such as your computer, can recognize the memory card you are using with printer?
To confirm, that is a SanDisk memory card that looks something like this - see the picture below:
OK, as you wish.
For any other issue, let me know.
