Hi, gracie0616!
So that the Community can help you better, we need to know exactly error messages or unexpected behavior you're seeing from your PIXMA MX452. That, and any other details you'd like to give will help the Community better understand your issue!
If this is a time-sensitive matter, search our knowledge base or contact our US-based technical support team at http://canon.us/SupportCF
Thanks and have a great day!
