Hello Sandi49,
Welcome to the HP Forums!
I understand your Photosmart C6280 is printing slow and making a "Clacking Noise". Please make sure this printer is plugged into a direct wall, not surge protector. Have you ever experienced a paper jam within this printer?
How is this printer connected? Wireless or USB?
What is your operating system on your computer? Windows or Mac?
Please verify this information and I will assist you further. :smileyhappy:
