    GR 3750 horizontal print position issues

    Howdy, this is my first post I've been lurking for a while soaking up some knowledge.

    I just got a Riso gr3750 and am having trouble with print position. I fixed the vertical position by adjusting the timing - that is fine. My problem is the horizontal position - the machine is printing everything about a quarter inch to the left consistently. I made a few masters and double checked that the original was dead center every time. Is there a way to adjust this easily? I considered just marking a different center point in the scanning bed as a workaround but I would like to figure out how to fix it the right way.

    Adjustment knob on paper feed tray to move horizontal position of the paper.
