As much as possible, keep the printer free from dust and debris. Clean the outside of the printer with a lightly water-dampened cloth. Clean the inside with a dry, lint-free cloth. CAUTION Do not use ammonia-based cleaners on or around the printer. While cleaning the printer, be careful not to touch the transfer roller (located underneath the toner cartridge). Skin oils on the roller can cause print quality problems. Using the Printer Cleaning Processes During the printing process, paper, toner and dust particles can accumulate inside the printer. Over time, this buildup can cause print quality problems such as toner specks or smearing. This printer has two cleaning modes that can correct and prevent these types of problems. Note In order for the engine cleaning page to work properly, print the page on copier-grade paper, not bond or rough paper. Engine Cleaning This process uses copier-grade paper from Tray 2 to remove dust and toner from the paper path. Use this process if you are experiencing toner specks or dots on printouts. This process will provide a blank page which should be discarded.
