Change the type of paper you use if the pages come out with a gray background. The cotton fibers inside the paper can cause a buildup of static electricity, which can in turn cause the gray tint on the paper. If the paper prints all or mostly black, the imaging drum should be replaced.

Fix pockmarks on the paper by changing the fuser cleaning pad. Open the top cover of the printer and locate the blue fuser cleaning pad. Move the right hand tab slightly to the left and lift the used pad out of the printer. Insert the new fuser cleaning pad, being careful not to get the ink on your hands. Slide it in place, then move the tab over to lock it in place. Replacing the fuser cleaning pad can also resolve problems with streaks or spots on the paper.
