Why is my printer still showing that it has a paper jam?

Ï printed out some papers yesterday morning on my Canon iP2600 printer with no problem. Yesterday afternoon, the paper feed tray kept pulling to the right causing the paper to jam. I discovered that my granddaughter had drooped a ballpoint pen down inside the paper load tray. I removed the pen and tried to print and now it keeps showing me that I have a paper jam and will not print at all. It won't even take the paper. I need help figuring out what the problem could be.
