canon pixma TR4700 not printing double sided

[kf95]

I have changed all of the settings on my printer and on the computer to duplex automatic double sided printing but everytime I click to print double sided the printer takes the paper back into the printer than spits it out without printing the second page on the back and says error that there is a paper jam when the computer actually already spit the paper out so there is no paper inside at all.
