@WolfHD, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
I understand you're experiencing an issue where your HP DeskJet 3750 is printing only in black and white, even though a new color ink cartridge has been installed and shows as full. Let's walk through some steps to resolve this:

Check Print Settings

Sometimes, the print settings may be set to "Black & White" or "Grayscale" by default.

On Windows:

• Open the document you want to print.
• Click File > Print > Printer Properties.
• Look for a Color or Advanced tab.
• Ensure Color is selected instead of Black & White or Grayscale.
• Click OK and try printing again.

On macOS:

• Open the document and click File > Print.
• Click Show Details (if available).
• Look for a Color Options or Media & Quality section.
• Make sure Print in Color is selected.

Run Printhead Cleaning

Even though the cartridge is new, the printhead might be clogged.

• Open the HP Smart app.
• Select your printer > Printer Settings > Tools > Clean Printheads.
• Follow the on-screen instructions and print a test page.

If the issue persists, try a second-level cleaning from the same menu.

Check Cartridge Installation

Make sure the color cartridge is properly seated:

• Open the cartridge access door.
• Remove and reinsert the color cartridge.
• Ensure it clicks into place securely.

Print a Diagnostic Page

This helps verify if the printer is detecting and using the color cartridge.

• Press and hold the Start Copy Color and Cancel buttons together for 3 seconds.
• A Printer Status Report should print.
• Check if any color appears on the page.

If the diagnostic page prints in color, the issue is likely with the software settings.
