Hey,

Have an Iradv4225 with booklet finisher, everything works fine, duplex, stapling etc, until the customer wants to do booklets with saddle stich, the booklet is done but when it comes to staple, the front staple comes out perfectly, the 2nd staple (rear) doesnt come out at all, not even perferations where the staple should be, then it would jam. However, if i do the booklet without the saddle stich, it will fold and come out perfectly.

I replaced the staple assembly, but still does exactly the same. I am looking at replacing the finisher controller pcb , any ideas?
