Cleaning/Preventive Maintenance
To clean the lenses, use a lint-free cloth and a mild non-abrasive detergent such as liquid dish soap mixed with water. It is important to keep the bill path, rollers, and belts clean. Use a soft lint-free cloth or a cotton swab to wipe dirt and stains from the surfaces of the magnetic and optical sensors, rollers and belts. The sensor lenses are transparent, and made of a polymer material. Handle them with care. Repeat the cleaning process as needed until the Transport path id free of contaminants (See Figure 2-16).
