Epson R380 losing Print DVD settings?

Bought an Epson R380 last month, I use it only for the CD\DVD printing. I have noticed that the alignment of the DVD printing will go off slightly after a few (3 or more) printings of a DVD. Has anyone else noticed this?

I have the alignment in the printer set to 0.0 & 0.0, I use the PrintCd software that it came with and have set that to Horizontal 0.1 & Vertical 0.4

No matter the changes I make to the settings the first two or so will come out fine after that it will shift slightly down & get progressively worse with each additional DVD printed like it is losing the original setting or is not lining up correctly inside.

PS: I do ensure that the tray is lined up correctly to the white arrow.
