Print bed not parallel to horizontal shaft suspended over bed that supports the print head.

I just received my Prusa Mini+ pre-assembled model and just set it up.  All the tests were run and completed successfully. When I ran First Layer Calibration I noticed that prints were OK on the right side of the bed but terrible on the left side.  It appeared to me that the nozzle was further away from bed on the left side.  Yet the mesh bed leveling routine was automatically run before the First Layer Calibration was performed.  

So I moved the print head to the center of the bed and using calipers took measurements of the distance between the print bed and lower horizontal arm that supports the print arm. The distance on the left side was 68mm and the distance between the bed and horizontal shaft on the right side was 58mm.  Any ideas on why that would be so far off?

This is my first attempt at 3D printing but I thought I had followed the directions precisely. 

Any help would be appreciated.

Was the same on my pre-assembled.

If you loosen these screws at the front and back, you can move the aluminum profile on which the Z-axis sits in the front&back plates slightly and thus align the Z-axis at perpendicular to the print bed.

@glowin

Thanks Glowin!  That worked for me!

I'm still working on getting good bed adhesion and an accurate calibrated first layer but I'm making slow and steady progress.
