After replacing OEM Toner and Fuser Unit including a new Transfer Roller print quality is still Faded or Light Prints, not vibrant BLACK as I am use to getting from my printer. It seems that another internal component has failed. It seems enough negative charge from the Transfer Roller is not passing to the paper to allow toner to JUMP or attract from OPC drum to paper. Please can anyone say what I need to replace or check to fix this issue.. Test Print - Faded_HP Forum.jpg

Try cleaning laser and mirror optics inside, if dirty the print can get light.
