Error message supply system problem

[KT1969]

my HP OfficeJet Pro 9015 is showing error. Message: supply system, problem with the magenta and black cartridges. I just replaced these with brand new HP ink cartridges, 962. I have done all the troubleshooting suggestions I’ve turned off my printer and turned it back on, I’ve cleaned the contacts, I’ve reinserted the cartridges, nothing is changing the error, message .

Hi @KT1969,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I know how frustrating it can be when your HP OfficeJet Pro 9015 printer doesn’t recognize brand-new cartridges, especially when you've already done everything right. I’m here to help you get this sorted.
 

You've done a great job trying the right steps — powering the printer off and on, cleaning the contacts, and reinserting the cartridges. Since you're still seeing the "Supply System Problem – with the Magenta and Black cartridges" even after installing genuine HP 962 ink, we’ll take the next steps together.

1. Double-check the ink cartridge contacts

Even though you've cleaned the contacts, here's a quick refresher:

• Use a lint-free cloth slightly dampened with distilled water.
• Gently wipe the copper-colored contacts on the cartridges and the corresponding contacts inside the printer.
• Let everything dry fully before reinserting the cartridges.

2. Reset the printer (a full power reset)

Sometimes a deeper reset helps clear supply system errors:

1. Turn off the printer and unplug the power cord from the wall.
2. Wait at least 60 seconds.
3. Plug it back in directly to a wall outlet (not a power strip), and power the printer back on.
4. Reinsert the cartridges once prompted.

3. Try a different set of cartridges (if available)

If you have access to another set of HP 962 ink cartridges, even if they’re partially used, try inserting them to see if the error clears. This helps confirm whether the issue is with the cartridges or the internal supply system.

I hope this helps.

Take care and have a good day.
