What could be causing toner smudges in my printout?

• Your paper may be moist or damp. Do not store your paper in a humid or damp environment. You may not be using the correct type of paper for your printer. If the surface of your paper is too rough, printed characters may appear distorted or broken. Smooth, high-quality copier paper is recommended for best results. See "Specifications" in your user's manual for information on choosing paper. Turn off the printer. Remove the developer cartridge, shake it from side to side to distribute the toner, and wipe the cartridge's bottom with a clean, dry, lint-free cloth. Clean the paper path inside the printer using a clean, soft, dry, lint-free cloth. Clean internal printer components by printing three pages with only one character per page. If the problem remains, replace the developer cartridge.
