Need Help Vertical Axis issue (Mimaki CG-130FX)


New Member
Our Mimaki CG-130FX has been coming up short on the vertical axis. For instance, If I were to plot a rectangle that is (1" x 90") it actually plots approx. (1" x 85.5"). This problem is mathematically consistent and increases the further the distance of the plot is. I've been able to account for this and achieve correct distances assuming that all vertical plots/cuts will be short by 1/180th of total distance. I'm worried that this may be a mechanical issue but am uncertain if there is a way to calibrate the machine. Thoughts?
