Chapter 6 Handling Cleaning the Case Turn off the printer before cleaning the case, and wipe the dirt off the case with a dry or slightly damp cloth. If it is very dirty, soak a cloth in a neutral liquid detergent, tightly wring it out, and wipe the dirt away. Never clean the product with alcohol, benzine, thinner, or other such solvents.
