Problem with VS-300, deflected nozzle and banding issues. Cant seem to fix it :(

Hi everyone, i'm having some issues with my Roland VS-300. I started a print and realized the head rubbed slightly on the edge of the vinyl. I did a manual cleaning and a few normal cleaning to make sure everything was ok. However I have some nozzle deflection in my black. I'm running a double CMYK setup. I did several medium cleaning, normal cleaning, changed the wiper, felt, capping station, head soak for 4 hours, head soak for 12 hours, printed solid black 100%K hoping to unclog the nozzle but I have had no luck so far. The big problem is whenever I print something fully black, im getting banding because of this nozzle deflection. I tried different settings such as using Max Density and other profiles in Versaworks which makes it a bit better but its still noticeable up close. The print head if pretty new, I ran about 2-3 cartridges of each color since I changed it 2 years ago or so.
 
I'm really hoping to find a solution because im not planning to spend another 3500$ on another head. I find the VS print heads really finicky and expensive to replace. Would appreciate if anyone can give me recommendations or things to try. Thanks
Pat

That test print looks pretty good except for that little deflection, however I wouldn't think that just the one nozzle would cause that much problem. Did you check your head alignment to make sure all was in line.
