Hazy or "wobbled" black print - PIXMA iX6820

[ritnwu47]

My PIXMA iX6820 has issues with printing blacks - they seem hazy or "wobbled," and gray rather than black.

It seems to mostly/just be an issue with the color black.I've done deep cleaning using the printer utility several times. I've replaced the ink with brand new ink. I've cleaned the timing strip carefully with alcohol.

The images below are printed at "Fine" quality on regular printing paper.

I'd be really grateful for any thoughts or help.

No dice. Did not work. Strip looks perfectly clean and brushed with alcohol and q-tip. No change. Any other ideas?
