@aoprych,

Good Day.  Thank you for posting your query in the HP community.  I read the post regarding issues with print quality as magenta is not printing. I will be delighted to assist you here.

Superb description and spectacular troubleshooting and commendable diagnosis of the issue before posting. Kudos to you for that. 🙂

For better clarity and to assist you better I would require more information regarding this:

• Did this happen after a recent power outage or surge?
• Did you make copies directly from the printer and check if Magenta prints?

For now, please try these steps:

Please perform a hard reset on the printer from this link: https://hp.care/2wzgpF5 and follow instructions from the section “Step 1: Reset the printer”

Then perform all the prescribed steps from this link: https://hp.care/2KfbpHM (Fixing Print Quality Problems for the HP Officejet 7500A (E910a and E910c) Wide Format e-All-in-One Printer Series) if it has not been done already.

• Solution one: Use genuine HP cartridges
• Solution two: Check the paper
• Solution three: Check the print settings
• Solution four: Check ink levels, and then replace low or empty cartridges
• Solution five: Print and evaluate a print quality report and troubleshoot defects
• Solution six: Update the printer firmware
• Solution seven: Replace the printhead (here reseat the printhead 3 times) you don’t need to replace it as it is new.

If the issue continues, then contact HP phone support to get the printer replaced. I am being honest about it by keeping your best interest in mind without beating around the bush.
