[Ray8227]

I'm printing on a Color Laser Jet Pro MFP M477 and every time I print for the last month the printer makes a very loud moaning sound like it needs oil or something.

Hi @Ray8227 

Welcome to HP Support Community.

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

A loud moaning sound from your HP Color LaserJet Pro MFP M477 could indicate a few potential issues. Here are some steps to help troubleshoot the noise:

1. Check for Obstructions

• Inspect Inside the Printer: Open the printer and check for any paper jams or foreign objects that might be causing the noise. Remove any debris you find.

2. Clean the Printer

• Dust and Debris: Dust buildup can cause operational noise. Use a soft, lint-free cloth to clean the inside of the printer, especially around the rollers and gears.

3. Examine the Toner Cartridges

• Reseat Cartridges: Remove and reseat the toner cartridges to ensure they are properly installed. Sometimes, improper seating can cause noise.
• Check for Damage: Inspect the cartridges for any signs of damage or wear.

4. Listen for Mechanical Issues

• Check Rollers and Gears: If the noise is coming from the rollers or gears, there might be a mechanical issue. Look for any signs of wear or misalignment.

5. Update Firmware

• Ensure your printer's firmware is up to date. Sometimes, updates can resolve mechanical issues or improve performance.

6. Run Maintenance

• Use the printer's built-in maintenance options to perform any recommended maintenance tasks. This can sometimes resolve noise issues.

I hope this helps.

Take care and have a good day.
