Sp300V/Versa - Black streaking problem.

Greetings Folks,

I am having an issue with printing large areas of black on my SP300.

I am using the Versa Settings of:

Quality:
standard
Standard, Generic Vinyl II-B
Preset: Sign & Display

Color Management:
Set Black Leve: +5

Test Print shows no issues with black printhead.

My black prints show streaking as in the photo.

the bottom 3/4'ths was printed via Versaworks using the above settings.

the top 1/4 of the photo (nice dark black) I printed using flexi (ignore the finger streak at the top right of the flexi print



Any suggestions of where I need to be looking to address this issue?

As Usual, thanks in advance.
