HP Designjet T120 uneven printing

HP Recommended
Designjet T120
Microsoft Windows 10 (64-bit)

Our designjet T120 prints unevenly.  It prints in "bands".  Here is a picture of what it does.  I've cleaned the ink heads AND replaced the printhead and it still does it.  What else can I do?FullSizeRender.jpg

I have exactly the same concern.  It appears to be software related, i.e. the printer driver.  I have been unable to resolve the issue.  The troubleshooting guide doesn't address this consistent, software problem.
