Cleaning the MFP To maintain print quality, clean the MFP thoroughly whenever print-quality problems occur and every time you replace the print cartridge. WARNING! Avoid touching the fusing area when cleaning the MFP. It can be hot. CAUTION To avoid permanent damage to the print cartridge, do not use ammonia-based cleaners on or around the MFP except as directed. Cleaning the outside of the MFP ● Clean the outside of the MFP if it is visibly marked. ● Use a soft, lint-free cloth dampened with water, or water and a mild detergent. Cleaning the touchscreen Clean the touchscreen whenever it is necessary to remove fingerprints or dust. Wipe the touchscreen gently with a clean, water-dampened, lint-free cloth. CAUTION Use water only. Solvents or cleaners can damage the touchscreen. Do not pour or spray water directly onto the touchscreen. To clean the scanner glass ● Clean the scanner glass only if dirt is visible, or if you are experiencing a decrease in copy quality, such as streaking. ● Clean the scanner glass by wiping it gently with a clean, slightly damp, lint-free cloth. Use an ammonia-based surface cleaner only when a water-dampened cloth does not clean the scanner glass. CAUTION Do not pour or spray liquids directly onto the scanner glass. Do not press hard on the glass surface. (You could break the glass). 230 Chapter 11 Managing and maintaining the MFP ENWW
