DF-710 finisher

[melacom]

I have a CS 3050 and just installed a DF-710 finisher and I am unable to get it to staple or feed to tray A the 3000 sheet bin. When I pick staple it tells me that option is not available, it tells me the same thing if i try to pick tray A. I am able to pick trays B and C for out puts and have the option on my screen to pick staple. Anyone tell me what I am missing?

So I have fixed my own problem I did a 906 and it reset the finisher.
