es453 Drawer 1 Duplex Jams

[AVux07]

I'm getting duplex jams from the top drawer, drawer 2 and the LCF work fine.

It'll feed the first copy and exit properly, the 2nd sheet will stop just before getting to the Reg. sensor on the first side. Main drive will run for 20 seconds or so and shutdown with code (don't remember it). Simplex works fine from drawer 1.

The machine has 10k on it but was damaged on the duplex side and needed to had the ADU and it's brackets replaced.

I notice there are 2 ADU cont. bd. numbers, could it be the wrong adu unit was installed, it was a used unit, perhaps a es350 model.

Also is there a timing loop value for drawer 1 that maybe adjusted for this problem?

Thanks

Fixed, the curved tabs on the ends of item #4 where both broken off, probably broke in shipping, the plate looked fine but taping it shut stopped the jamming for now till I can get a new one.
