What Do You Do When Your Printer Keeps Jamming?

 I had an event this morning and it would print 1 picture then get jammed. I took the paper out and put it back in many times and each time it begins to print and gets jammed again. Please let me know something as soon as possible because I'm scheduled for another event tonight but I'm not able to print.  Here's a picture of what the printer is doing to the paper.

Solution - 

If there's any gap in between the paper and the plastic sides it will cause that situation. Make sure the sides of the paper holder are pushed in tight.
