As for asking too much, Ask a thousand questions nicely and I will source the answer to every single one I can, or others will. but you would probably get much less helpful answers if you were to start just bashing Xerox, the product, the forum or its users. (You certainly haven't done this to be clear and I don't assume you would).
Anyway, here are the specs (Letter/Legal,Tabloid,A3,A4 can be folded)
I attached the CEIG for reference. (Page 21)
And here is where I put in my guess as to why the answer is no to the "Can it fold SRA4" question.
SRAX sizes tend to have 2 decimal places in their sizes, and the hardware in the Finisher is simply not accurate enough to reliably find dead center.
