Cleaning the machine If printing quality problems occur or if you use your machine in a dusty environment, you need to clean your machine regularly to keep the best printing condition and use your machine longer. Read the following precautions before cleaning the machine: any damages due to user's mis-handling is not covered by the warranty: 8 Cleaning the outside or display screen Clean the machine cabinet or the display screen with a soft, lint-free cloth. Dampen the cloth slightly with water, but be careful not to let any water drip onto or into the machine. • Turn the machine's power off and unplug all the power cords. • Do not disassemble the machine without following the instructions in this guide. • Do not clean the machine with cleaning materials containing large amounts of alcohol, solvent, or other strong substances. They can discolor or distort the cabinet. • Do not use a vacuum cleaner to clean the toner dust, we recommend you use a cloth or tissue dampened with water to clean it. If you use a vacuum cleaner, toner blows into the air and might be harmful to you. • When using a dampened cloth, be careful not to drip any water into the machine: it might cause an electric shock. • For more safety issues, refer to the safety information chapter in the User's Guide. 9 Cleaning the inside During the printing process, paper, toner, and dust particles can accumulate inside the machine. These accumulations can cause print quality problems, such as toner specks or smearing. Cleaning the inside of the machine clears and reduces printing quality problems. 4. Maintenance 392
