Ricoh tandem tray LCIT PB3050

I'm getting a jam comming out of tray 3 (the dreaded tandem tray) on an MPC5000, new install, less than 1000 impressions, the jam code is 53, it will jam on single copy or multiple copies, it appears that it may be multi-sheet feeding because even on single sheet, one will be in the registration roller and one will be about 4" out form the drawer. it is intermittant, it may go 50 to 100 with no problem then it may jam on everysheet after that. any ideas?

The only thing specific to that tray I have had has been the bottom plate being crooked because one of the belts on the sides skips.
