Horizontal banding issue - White line in all colors

HP Recommended
HP L330
Microsoft Windows 10 (64-bit)

Hi, I've been having some banding issue with my wide format latex 330. I've change all (literally all) printheads, updated the firmware, updated the HP Flexi RIP to the lattest version, I did an automatic and a manual printhead alignment, I did the sustrate advance calibration (manually, cause the L330 doesn't has OMAS)... but nothing change. All colors have an strange white banding, and its the same for all colors.
I need help please, I don't know what more I can do.

Have you tried cleaning carriage and printhead's contacts with ethyl alcohol?
