Epson ET-3850 - Alignment issues

[Moon_Man_3]

I just purchased an Epson ET-3850. I set it up very carefully and did an alignment check, even using magnification to ensure I got it right. However, when I print spreadsheets in landscape orientation, the horizontal lines have small jogs in them. It affects the letters too, in the same spots. I ran the alignment four more times, but with the same results.

It's just a small alignment issue. Nothing terrible, but still noticeable. Is something wrong with my new printer, or is this just life with an ink jet? Thanks!
