Hi Brenda,

Based on your description of the issue, it would appear as though the encoder/timing strip in your PIXMA MG7720 is dirty or smudged and would need to be cleaned.  To clean the encoder/timing strip, please follow the steps outlined in the following Knowledgebase Article available from Canon's web site:

After cleaning, please attempt to print again.
