R3000 Front Feeder Information

[NortheastPhotographic]

I am printing Hahnemuhle Fine Art Baryta gloss in my R3000. When using the sheet feeder recently I had a couple prints come out with slightly more boarder on one side, or even slightly diagonal on the page. Would using the front sheet feeder alleviate these alignment issues?

Also, if I am using the front feeder, does this eliminate the need to widen the platen gap? (which I must do to avoid head strikes with Fine Art Baryta).

Thanks!
