How do I fix blurry printing, already tried all the basic diagnostics?

HP Officejet Pro 8600Plus printing is blurry and light for all colors but blue. Was printing fine with refilled cartridges until a few weeks ago. Black ink got low and replaced with brand new HP black ink. Here's what I've tried multiple times that didn't help. What else can I try please?

-Clean printhead

-Align printhead

-Reset printer by unplugging several minutes

-Printing test page: blue boxes look fine. Yellow, red and blackall have vertical lines and faded colors. Black text is blurry and faded. Test pattern lines do not connect fully.

-Printing 20 black text pages to see if problem "resolved itself" as HP site says!!

Wear gloves.

Put print head in plastic dish with warm water and then put print head in plastic dish with alcohol. Do it over again one time. Put little amount of liquids to cover the head. Don't cover the board. Clean the board with alcohol.

Then dry it out and insert it on printer.and then rerun all checks.

If not work change the print head.
