Oddly enough, we hated those presses, they seemed to be an overthought PIA. It does hold 23 x 31's pretty well though. All of our folks can "see how it works" print wise, I've always thought it was pretty obvious, but yeah, some people don't want to think, just jam it through. To be fair, before I started printing, I had very little mechanical experience, but picked it up quickly once it was part of the job. I was a guitar teacher before that and mechanical knowledge didn't play a big part. I would rather print than teach guitar any day...
