One color is missing from my prints

[Bloomsbury]

Hi--I have an HP Deskjet 3636, used with a Windows 10 laptop. I just inserted brand-new YP ink cartridges. Black, yellow, and cyan print fine, but magenta doesn't print at all. In a color print, everything that should be red is yellow.

I tried looking up "clean ink cartridges" and "clean printhead," but was told to look in my HP folder, click on this printer model, and go to Print Assistant. My HP folder shows another HP printer I've used, but not this one--even though this printer is visible elsewhere, under "Printers & scanners." 

So, two related questions: 1) How do I get this particular printer into the HP folder? 2) How do I fix the magenta printing problem? Thanks!

You’ve done an excellent job of diagnosing the issue from your end. Superb effort and spectacular research were done as well.  Kudos to you on that score.  I take it as a privilege to share this platform with you.

To assist you with accurate information I would require more information regarding this:

• Did this happen after a software or Window update?
• Is it a wireless or USB connection?

Update Firmware if not done already by selecting the current OS.
