@Lucy251,

Welcome to HP Support Community.

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

If you've already gone through all the usual troubleshooting steps and are down to cleaning or replacing the printhead, here’s what I suggest:

1. Deep Clean the Printhead

Since the Photosmart 7520 has a built-in, non-removable printhead, you’ll need to clean it manually:

Use the printer’s built-in cleaning tool:

• On the printer’s control panel, go to Setup > Tools > Clean Printhead and run multiple cleaning cycles if necessary.
• Print a Print Quality Diagnostic Report to check if black ink improves.

Manual Cleaning (if automated cleaning fails):

• Remove the ink cartridges and set them aside.
• Use a lint-free cloth lightly dampened with distilled water or isopropyl alcohol (91%+ purity) to gently wipe the printhead's ink nozzles.
• Let it dry completely before reinserting the cartridges.
• Run another printhead cleaning cycle.

2. Try a Different Cartridge

Sometimes a bad ink cartridge (even if new) can cause this. Try:

• A brand-new, genuine HP 564XL black cartridge.
• Shaking the cartridge slightly to mix the ink.
• Checking for proper venting—ensure the small vent hole on top of the cartridge is open and not clogged.

3. Hard Reset

• Remove the power cord while the printer is on.
• Wait 2-3 minutes, then reconnect and turn it on.
• This can help reset internal ink system errors.

I hope this helps.

Take care and have a good day.
