Cleaning procedures Cleaning the toner cartridge area With a dry, lint-free cloth, wipe any residue from the paper path area and the toner cartridge cavity. NOTE: NOTE: Cleaning the toner cartridge area is not necessary on a regular basis. Before cleaning, look for excessive toner in the compartment. Cleaning the printer paper path This process uses copier-grade paper to remove dust and toner from the paper path. Do not use bond or rough paper.

This process will produce a page with toner debris, which should be discarded. 1 Ensure the printer is loaded with paper. 2 Ensure the printer is in the Ready state. 3 Press and hold the GO key for 20 seconds (if released before 20 seconds the printer will perform a reset). Paper will feed through the printer. After holding the GO key for 20 seconds, each of the three printer lights will blink until the cleaning process is complete.
