Since job is 1 sided you could tell it uncollated pads of 25 and then enter amount 425 or under the Copy Output Tab go to unollated then choose stacker tray or high Cap then the option for offset stacking should reveal iteself at that point enter offset number, in your case it would be 25.
Good Luck
I need 425 copies of a single page document, but I want to it print out in "sets" of 25 so I can put them in inner office mailboxes (for teachers). When I say "sets", I mean when it prints, it offsets the printed pieces 1/4" to the left in the output tray. How can I change the default "set" to a specific number? My eyes are crosseyed from standing over the machine, watching the counter, and grabbing a set of 25 as it stacks up.
