HP Designjet T530 prints white lines every 5.5 cm

My Designjet T530 will start printing a faint horizontal white line every 5.5 cm when I print a picture. It starts out fine but the line becomes more and more obvious as the print continues. I have aligned and cleaned the print heads, changed two of the ink cartridges (other two were full) and run the diagnostic. Printing picture on best quality helps but does not remove the problem entirely. Attached picture shows example, left side the beginning of the print, so you can see how it gets worse.

Have you performed a paper advance calibration using the your current media?

No luck with re-calibrating. =(
