Why is my printer making a loud clicking noise?

Needed to replace black ink cartridge, opened front door and removed cartridge. Left door open while I went to store to buy new cartridge. Wife said when I was gone, printer made a loud banging noise then stopped. Came home, replaced cartridge and now printer makes a loud rat-a-tat banging noise each time it prints something new. Have removed and re-installed both cartridges several times but still have loud banging noise. What’s up?
