Unfortunately inaccuracies that far off can only be fixed by formlabs. I would open up a support ticket. Based upon my experiences, you will have to have the unit shipped back for repairs and recalibration.

I wish I was able to tell you how to do it. We can’t calibrate the machine beyond the 4%. It has to be done by Formlabs.

I would open a support ticket for FL. They are the only ones who can fix your printers problem.
