Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Can you do a photocopying operation, even just in Black, and see if the photocopying capability of the printer still works? It may seem rather cautious, but I think that establishing that basic capability is important.
Put the machine into COPY mode, place a sheet face-down on the glass, and approve the copy.
If you got an 'insert memory device', you must have chosen a Scan... a Scan to Memory Device or Scan To USB probably.
(I regret that I am not able to offer Secure Remote service at this time; However, your request is still open to other Experts in this category, and one of them may pick up on it at any time.)
