I have an alignment failed problem on my HP Officejet Pro 8500a.
At first, I throughout I ran out of ink so I got new ink and it still didn't work
I tried cleaning the alignment sensor by taking it out and I am not sure I placed it back the right way.
The alignment still fails but I get slightly better results now.
I am adding a scane of my best alignment results and printheads cleaning results
Do you know where I can buy a new alignment sensor or maybe have any ideas on how to fix my problem?

Hi,
The problem is not with the alignment itself, but with the print quality which causes the alignment process to fail.
By your pictures, I can identify an issue with both Black and Magenta, assuming the ink levels are full it likely requires to replace both printheads:

Keep in mind that it could be faulty printheads and could be the printer hardware too, please consider it prior to spending any money on replacement parts, check if it worth the money invested or may better to replace a printer with a provided warranty and starter inks.

I changed both printheads and I can finally see a big improvement!
The black, blue and purple color works great but the yellow isn't
I added a scene of my printheads cleaning and alingment results.

Indeed there seems to be a big improvement.
One option would be a defective Black/Yellow printhead, another option would be a faulty Yello cartridge.
What is the printhead warranty end date? you may contact the retailer and try to replace it as part of its warranty, also trying another Yellow cartridge worth a try.
Other than that, the printer will likely require servicing:

Indeed this is likely, as the previous printhead have printed yellow but not black, while current one shows the opposite results.
