Paper jam going to output bin

Whenever I select printed output to be routed to the output bin on my Laserjet 1100, the first page will print but not completely eject into the output bin. The printer then jams with the second page partially fed, but no printing started on the second page. When I select to bypass the output bin, no jam occurs. I have installed the free separation pad offered by HP. Any help would be appreciated.

Thanks.
