Cleaning the Machine Note the following before cleaning your machine: - Make sure no document is stored in memory, then turn off the main power switch and disconnect the power cord. - Use a soft cloth to avoid scratching the components. - Do not use tissue paper, paper towels, or similar materials for cleaning; they can stick to the components or generate static charges. Never use volatile liquids such as thinners, benzene, acetone, or any other chemical cleaner to clean the machine. These can damage the machine components.
